Hint: Boss time attack mode:
Successfully complete either side story to see all the scenes from the side of the story that you chose or you can play the Bosses that you fought in a time attack mode. To get both the Hero and the Dark modes you have to complete both sides of the game.

Hint: Last stage:
Successfully complete both Hero and Dark side story modes. Enter story mode to access the "Last Stage?" option.

Hint: Extra Island level:
To get an extra Island level, you must get all the Emblems, including Kart, Timed Boss, and the emblems for all A rating. Once you have them all, which should total 180, the island next to the Green Forest level will have the face of Sonic on it. The new level is a 3D version of the Green Hills Zone, from Sonic The Hedgehog. This level has no missions, is very simple, and has many varying routes.

Hint: Extra costumes:
Get "A" ranks on every mission with the character you wish to get the costume for in two-player mode.
Cher Hung, Alex Wong, and UGUMAN.

If you get all "A" ranks for a character you will get that character with a new costume in two player mode. This changes what they do. For example, Eggman gets a power up every 10 rings instead of 20, and it is always the power laser. Tails on the other hand gets no power-ups, but he can move very fast.

Hint: Duplicate money:
This trick requires two memory cards. The Chao Garden and the adventure mode are stored as two separate files. You spend the money in the Chao Garden, but the money tracked on the adventures file. To duplicate money, copy the adventures file from memory card one to memory card two. Then, play the game. Use all the money to raise your Chaos. Once you have run out, delete the adventures file from memory card one and copy the file from memory card two. All the money you spent will be back, and everything you have done in the garden will still be present. For easy money, spend all the money on the most expensive items you can obtain and throw them into a Garden. Delete the adventures file from memory card one and copy the adventures file from memory card two to memory card one. Play the game, go to the Chao Garden, and sell all the items.
MDGLegends.

Hint: Duplicate rings:
In the Chao Garden, sell all you items (bucket, watermelon, pumpkin, eggshells, etc.). Do not sell items like Amy's Theme, Omachao's Theme or any other theme. All other items are fine. After selling all your items, or just the ones that will sell for the most rings, reset the game. You will have all your items back, plus all the rings obtained from selling your Items. Continue to do this repeatedly. By selling more than one item you will gain more rings faster. Also, if you had already reset the game and accidentally spent rings you meant to spend on something else, take it to the Garden to drop it off, save the game, then sell the item and reset. You will still have the item and get back most of the rings you spent. Do not try to experiment with this trick, for example buying an item then resetting the game in attempt to still have the item. It will not work.

Hint: Duplicating Chao:
This trick requires two memory cards (with another Sonic Adventure 2 Battle file on the second card), a link cable, and a Game Boy Advance. Put the Chao to be duplicated onto the Chao Transporter. Drop off your Chao to the Game Boy Advance. Then, go to "Move" on the Chao Transporter and transfer your real Chao (not the one in the Game Boy Advance) to a Sonic Adventure 2 Battle file on the second memory card. Next, pick up your Chao copy from the Game Boy Advance and transfer it to the Gamecube. You can now move back your real Chao from the other memory card to the first file you were working with.
Eric Padua.

This trick requires two memory cards. To get two free normal Chaos at one time, put two memory cards in the slots. Transfer all your Chao into one memory card (through the GBA Station). Erase Chao data on the first memory card, transfer the Chaos back, and then you will find two Chao eggs. Note: If you have acquired the Dark and Hero gardens, they will be lost. You have to earn them back again with babies. Also, If all your Chao do not fit on the memory card, either get another memory card, or you will lose them.
equinn1 and BlueDevil8945.

Use the following trick to copying a Chao with two memory cards and no Game Boy Advance. Put two memory cards into the Gamecube. Next, copy your Sonic Adventure Battle 2 file from the first memory card over to the second memory card. This will delete your Sonic Adventure Battle 2 file on the second memory card if you had one. Next, go to the Chao Garden (it does not matter which one, on which card) and go to the transporter (the big Game Boy Advance), select "Move Chao", and transfer whichever Chao you want from the second memory card to the first. If you do not want the file on the second, delete it. You can do this as many times as needed.
Avi.

This trick requires two memory cards and a Game Boy Advance with link cable. Take a Chao to the Chao transporter. Drop off the Chao in the Game Boy Advance. Then, go back in and pick it up. Immediately after you select "pick up", disconnect the link cable. If done correctly, you will have the Chao both in the Game Boy Advance and the Chao Garden. Move the Chao in the garden to the other memory card. Then, move the one in the Game Boy Advance to the first memory card. Note: If you do not move the one in the first memory card to the second memory card and try to pick up the Chao on the Game Boy Advance, it will erase the Chao in the garden, leaving only one Chao.
Jon K.

To copy a Chao with only one memory card, you need a Game Boy Advance and a link cable. First, put a copy of the desired Chao into the Game Boy Advance and unplug it. Save the game and turn off the Game Cube. Remove the memory card and plug in the Game Boy Advance. Then, go to the Chao Garden by entering the Emblem Results screen and selecting either "Chao Race" or "Chao Karate". Pick up your Chao, then insert the memory card into slot B. Then, simply move the Chao into the memory card.
TheAlmightyChaoGod.

This trick requires two memory cards. Enter the Chao garden then, pick up the Chao to be duplicated. Remove your memory card. Walk to the Chao Transporter and select "Move". Then, try to move the Chao you wish to duplicate to the other memory card. The message "No memory card detected in slot 1. Continue without saving?" will appear. Select "Yes". Once it has transferred, turn off the Gamecube. You should now have the Chao on two memory cards. Note: If you try to move one of the duplicated Chaos to another memory card with the same Chao already on it, there is a chance it will delete that Chao. This will also work with eggs.
Stan Dellinger.

This trick requires two memory cards with Sonic Adventure 2 Battle saved games. Have both memory cards in the Gamecube. Then, go to any Chao Garden. Go to the Game Boy Advance. Then, select "Move". Before choosing the desired the Chao, switch the memory cards in each other's place. Then, choose the Chao you want to trade or move. Save by choosing the orange arrow. It will automatically take you out of the Game Boy Advance. Then, switch the memory cards back to their original positions and save. Go back in the Chao Garden where you moved the chao. You should put it in the same one of which you have the one you copied. Look around and you will see the two of them.

Hint: Hero Garden for Chao:
Take a Chao and raise it with a Hero so that it will resemble a Hero. Wait until it cocoons into an angel-like Chao (it will have a halo). Then, take the stairs going up at the Chao Lobby to reach the Hero Garden.
Jenni.

Hint: Dark Garden for Chao:
Take a Chao and raise it with a Dark character. Feed and train it until it cocoons. After it evolves, stairs will appear at the Chao Lobby. Follow them to reach the Dark Garden.

Go to Pumpkin Hill and find the Skeleton Dog. Exit and do it again until you have maxed the line. Go to the Garden with Knuckles and drop off the Dogs. Exit the garden than go back in with a Dark character. The dogs should still be in there. Keep doing this.

Hint: Tiny Chao Garden flipping card game:
If you play the flipping card game, when the Chao walks by and pushes the card, quickly press A + B. It will automatically stumble and the card will flip. You will see an answer Note: You can only do this once with every card game that you start.
Fabian Russ.

Hint: Chao expressions:
Your Chao's expressions depend on how many seconds you shake the egg before it hatches. About six seconds results in the V face and ten seconds for no expression face. To get the very wide smile you may have to experiment.
cher hung.

Hint: Soon to evolve Chao:
Your Chao is close to transforming if it starts to sleep often.
Lolyshot64.

Hint: Faster evolution:
To make your Chao evolve faster, feed it a lot of fruit, animals, and Chaos Drives. Wait a half hour. If they did not evolve yet, do it again. Note: You may miss seeing that Chao evolve.
Kevin.

To have a Chao evolve immediately, raise its Stamina to level 15 or 16. Note: By raising it to level 16, as soon as you walk into the garden it will evolve unless it is drowning or swimming.
Ansy Francois.

To very quickly evolve your Chao follow these steps. First, get any Chao of your choice. You can buy one or just use a spotted one. Select what type you want to evolve your Chao into (Hero, Dark, Running, Fly, Swim, or Power). For Run, Fly, Swim, or Power, get that skill to level 4 by using Chaos Drives (yellow for Swim, green for Run, red for Power, and purple for Fly). If you want to get it to be a Hero, pet it with Sonic, Tails, or Knuckles until it has two little ball things coming out of his head. For a Dark Chao, pet it with Shadow, Eggman, or Rouge until it has a pointed tail and head. Once you get your Chao to your chosen type, go into the garden where your Chao is located, stand there, and allow the game to idle for about two hour. Make sure your character is in the same garden as your Chao. When you return, your Chao should be very close to evolving if it already has not. Its stamina will also have risen by two to four levels.

Hint: Advanced evolutions:
Note: the first stat is the type you should make it and the second is the stat that you should raise very high after it evolves. This works best with Spotted Egg Chao.

Full Red Chao: Power + Power
Hydralisk Chao: Power + Swim
Volcano Chao: Power + Fly
Can Opener Chao: Power + Run
Sumo Chao: Swim + Power
Slicing Chao: Swim + Swim
Sea Monster Chao: Swim + Fly
Scorpion Chao: Fly + Power
Armor Chao: Fly + Swim
Nights Chao: Fly + Fly
Ram Chao: Fly + Run
Boxing Chao: Run + Power
Life Form Chao: Run + Swim
Elf Chao: Run + Fly
Sonic Chao: Run + Run
Tough Curl Chao: Stamina + Power
Shark Chao: Stamina + Swim
Tall Chao: Stamina + Stamina

Hint: Different Chao types:
You can make your Chao different types (for example, Running, Power, etc.) by giving your Chao a large amount of the same colored Chaos Drives. Pet your Chao with the either a Hero or Dark character. If you give your Chao green Chao Drives, then it will be a Running type. If yellow, it will be a Swimming type. If red, it will be a Power type. If purple, it will be a Flying type.

Hint: Different Chao head:
If you want your Chao to have an item on his head, such as a skull or a pumpkin, get a Skeleton Dog (small animal) which can be found on Church Mountain in Pumpkin Hill, as well as some other levels. Go to the Chao Garden and give a Chao the Skeleton Dog. Then, give it the item you want placed on his head. Skulls can be found by digging with Knuckles or Rouge in the Dark Garden; Pumpkins can be found by digging in the Chao or Hero gardens; and other items such as a Cardboard Box can be purchased in the Black Market in the Chao Kindergarten.

Hint: Big Chao smile:
When you get an egg, pick it up and swing it for ten seconds. When it hatches the Chao will have a big smile.
Austin Dave.

Hint: Free toys for Chao:
Take your Chao to school. Whatever the lesson is, they should bring something related back. For example, if the lesson is tambourine they will bring one back with a star on it; if the lesson is flute, they will bring one back.
kbrockman1.

Hint: Free fruits for Chao:
Note: Sonic Advance and the Game Boy Advance link cable are required for this trick. Buy the fruits on Sonic Advance. Go to any Chao Garden and enter the Chao Transporter. Link to Sonic Advance and transfer the fruits for free.
Jake Gardner.

Hint: Attack Chao while flying:
In order to do this, you must be in either the Neutral or Hero Garden. As Tails, get a Chao to fly. When it is flying, have Tails also fly. Move directly underneath it when you are flying. The Chao will get hurt by the tails. Note: This may make your Chao dislike you.
Kevin.

Hint: Chao swimming or flying:
To get your Chao to swim, give it lots of animals that can swim. To make them fly, give them some flying type animals and bring them to the tallest cliff. Set it by the edge and he/she will walk off and start flying. Note: It may not fly the first time -- keep trying.
cher hung.

For a swimming type, give a Chao a lot of animals that can swim and yellow Chaos Drives. Note: Swim type animals may decrease other abilities, such as running, power, or flying. At level 3, your Chao will be able to swim. You will soon notice that your Chao swims on its belly.
chaomaster.

Hint: Wide smile on Chao:
When it is in the egg form, whistle to it five times then throw it at the wall. It should appear with a wide smile on its face.
SkyGlower.

Hint: Chao band or choir:
When one Chao starts to play an instrument or sing, pick up other Chaos and put them next to the singing/playing Chao. It will also start playing. Continue doing this and you will have a band/choir. Note: This works with all activities except for drawing. Some Chao may just sit down to watch and shake their heads to the beat.
cher hung.

Hint: Neutral Chao:
To make a Neutral Chao, you must have a Chao Garden with all six players. Bring each player in and hit the Chao, either by pressing Y until you get the attack option or by jumping on it. When it is starting to become black, start hitting it with evil characters, and vice versa. After awhile, the Chao turn a pinkish color. Soon afterwards it will evolve into an orange color. The Neutral Chaos are a lot better because you can enter them in the Hero and Dark races. Note: It is best to have the Chao with 7 to 14 stamina so that it is ready to evolve before starting this, and make sure you have it ready to transform in to the correct skill type.

Hint: Chaos Chao:
In order to acquire the immortal Chaos Chao reincarnate a Chao at least two times. A reincarnation consists of two transformations (or at least their definition of a transformation). This means that your Chao must create a tear-shaped cocoon around it self twice. After this has been accomplished, give your Chao (hero, neutral, or dark) one of each animal. On the third transformation, your Chao will become a Chaos Chao. Note: This will not work if your Chao dislikes you.
DrEggman7.

To get the Hero Chaos Chao, you must have your Chao transform at least two times and already have it a Hero Chao before it transforms. This means that your Chao (after it has evolved into Hero, Neutral, or Dark) gets in a pink cocoon twice. To do this, you must make you Chao like you by petting it, feeding it with only Sonic, Knuckles, and Tails, and not throwing it. If after you make your Chao a Hero, Neutral, or Dark Chao and it goes into another cocoon and the cocoon is gray, get out of the garden or turn off your game. A gray color means it will die instead of rebirthing. If it is pink, then stay in the garden. After you have it transformed twice, give it one of all 21 animals in no particular order. Do not give it any animals before this. After you find and feed all the animals to your Chao, feed it fruit. If it does not want the fruit and keeps going to sleep or throws it away, keep waking it up and giving it fruit until it starts to cocoon. After your Chao comes out of the cocoon and it is a Hero Chaos Chao, it will have big wing-looking things coming out of its head, a gold halo, and its hands, feet, and the end of the things coming out of its head will be translucent pink. Its body will be white.
Chaoschaomaster.

To get the Dark Chaos Chao, your Chao must be a Dark Chao. Repeat the process described above for the Hero Chaos Chao, except use Dr. Eggman, Shadow, and Rouge. If it is a Dark Chaos Chao, it will have horns coming out of its head, a blue flame instead of a dot floating above its head, a wing-looking thing coming out of the bottom of the back of its head, a red back, a black body, hands that look like flames, and it will have the pointed tail.
Chaoschaomaster.

To get the Neutral Chaos Chao, your Chao must be a Neutral Chao. Repeat the process described above for the Hero Chaos Chao above, except use all the characters equally.
Chaoschaomaster.

Hint: Chaos 0 Chao:
This trick requires a Game Boy Advance, Sonic Advance, and a link cable. Play the first stage on Sonic Advance until you have 14,000 rings. Then, buy an aquamarine egg. Transfer it to the Gamecube. Do the same as you would for a light chaos Chao. When it evolves, it will look like Chaos 0 from Sonic.
Bacon.

This trick requires a Game Boy Advance, Sonic Advance, and a link cable. Go to the Tiny Chao Garden on Sonic Advance and buy an aquamarine egg. Transfer it to the GameCube, and hatch it. Next, give it Yellow Drives with both Hero and Dark characters. Finally, feed it some nuts and it will make a blue cocoon. If done correctly, you should have a Neutral Swimming type that looks a lot like Chaos 0.

Hint: Black and blue Chao:
Note: This trick requires have Sonic Adventure DX with Amy's missions completed, a Game Boy Advance, and link cable. First go to the Egg Carrier with Amy. Go to the prison she was locked in and where the scene with E-102 and her took place. Go to the cage next to where Amy was and pick up the egg. Take the egg to a Chao Garden and hatch it. Send the Chao to the Sonic Advance or Sonic Advance 2 Tiny Chao Garden. From there, put it in Sonic Adventure 2 Battle. Go to the Chao Garden to retrieve your new black and blue Chao from the Game Boy Advance.
simplycherry.

This trick requires a Sonic Chao and a Shadow Chao. Feed them an egg fertile fruit. They should show flowers around them. Bring the other Chao in front of them and they should mate. Note: When the newborn Chao is born, it will have ranks depending on its parents.

Hint: Blood red Chao:
To get a blood red Chao with bright red hands and feet, breed a regularly colored Shadow Chao and a red Chao.
Phoenix K..

Hint: Cream the rabbit Chao:
Get an orange Chao then transform it into a water Hero. Do this repeatedly until its ears are long. When it is an adult, give it about five Rabbits, or until it is a full rabbit. Then, give it Skeleton Dogs until the ears are gone, and all that remains are the arms, legs, and tail. If you can get a two-toned orange and yellow Chao, use it instead.
lcardenas.

Hint: Devil Chao:
Have a Chao reincarnate (the thing with the pink cocoon) twice. Then, give one of every animal once, and make sure it is a Dark Chao. Then, make it reincarnate again. It may hatch as a Devil Chao or turn into one once it cocoons (blue). Note: To make an Angel Chao, follow all the steps for a Devil Chao, except the Chao must be a Hero Chao for its second reincarnation.
Vicki Carey.

Hint: Dragon Chao:
Buy a purple Chao from the Black Market and feed it plenty of Dragon animals.
Bnb4mj.

Hint: Flame head Chao:
To get a blue flame Chao, raise a red Chao with Knuckles until it grows two spikes on it head. Then, go into Chao World and pet that Chao repeatedly for a long time. It should grow two ears on the top of its head. After that, pet it again repeatedly. A blue flame will appear on top of its head.
InflateAPal.

To get a blue flame Chao, go to the Black Market with a hero character and buy a lime green egg (requires 125 or more emblems). Bring the egg into the Hero garden and hatch it by rocking it (pick it up and hold B). Once hatched, feed it a Sea Monster (from the Hidden Base maze). Then, go back into the Black Market and buy a Chao Fruit. Feed it the fruit, then feed it a Hero Chao Nut. After it finishes, the ball above its head should be a blue and orange flame.
Buzz Loftus.

To get any type of flame head Chao, raise your Chao to be a Hero, Dark, or Neutral type. When it evolves into one, give it three Green Lagoon Monsters, which can be found as Tails when you have to infiltrate Eggman's base.
Sergioneed4spd.

Give a Chao at least three Half Fish or a sea monster. You can find them in the Jungle level as Sonic.
AJ and Scott Thomas.

Get a green lizard and feed it to your Chao. If it does not get a flame, do it several times again until it does.
metsrock62.

Hint: Ghost Chao:
Get a transparent Chao of any color. Breed it with a shiny white Chao. Save the shiny white's egg shell. The Chao should appear from the egg invisible. If it is invisible (except for the eyes, mouth, wings, and ball), give it some Skele-Dogs and put the egg shell from the shiny white on its head. Then, give it bats so that its wings disappear and use only Chao Drives to make it fly (recommended that it be higher than the rest), swim (needs at least 100 experience to learn), and walk (needs at least 50 experience to learn). , Make the fly stat very high. When done with the stats, give it some Half-Fishes to make its ball a flame. You now have a ghost Chao that floats and flies around your garden.
alien.creatures.

Hint: Jack O'Lantern Chao:
Buy an orange Chao egg. Hatch the egg. Raise it Dark. When it evolves it will have bat wings if you raised it with Shadow. Give it Skeleton Dogs until it loses all its animal parts. Then, dig in the Neutral Garden to find a pumpkin. Give it to your Chao. It will look like it has a jack o' lantern on its head. Add the final touches by giving it Half Fish until it gets a flame over its head.
ryan.

Hint: Link Chao:
Get a lime green Chao egg and raise it to a neutral/swimming type. Then, raise its stats to something around the following:

Swim level 10 to 30
Fly level 30 (in case if you give it "Roc's Cape")
Run level 30 (for the speed boots from "Link to the Past")
Power level. 20 (to represent the power from the Master Sword)
Stamina level 7 to 15 (due to stamina requirements for evolving)

For the final touches you can add the following:

Condor Wings: "Roc's Cape"
Boar Feet: "Speed Boots"
and a Shovel

These things are optional and if included, might require some tweaking to get it correct. You have a Link Chao, and if you do the same for a red, blue, and a purple Chao you can have the Four Swords gang.
Steeveeo3000.

Hint: Sonic Chao:
Feed this Chao nothing but green animals/chaos drives and some fruits with a Hero and Dark character so you will have a neutral Chao. When the Chao evolves, you will have a Sonic Chao. After it evolves, feed it more green animals/chaos drive with Sonic only to make the spikes more like him.
Maurquice Straughter.

Hint: Hyper Shadow Chao:
Breed a Shiny Black Chao and raise it in mainly Running and minimal everything else. Evolve it Dark.
SegaDragon.

Hint: Super Sonic Chao:

Hatch a Shiny Yellow Egg and feed this Chao nothing but green animals/chaos drives and some fruits with Hero and Dark characters so you will have a neutral Chao. When the Chao evolves, you will have a Super Sonic Chao. After it evolves, feed it more green animals/chaos drives with Sonic only to make the spikes more like him.
TMCC.

Get a Gold Chao. Raise it with both sides. Give it lots of Green Chao Drives with both sides nicely and it will eventually evolve.
Marius_555.

Get a shiny yellow egg, then make it a Sonic Chao. Once completed, give it Power animals and Chaos Drives. It should look like Super Sonic. Note: Make it dark first so that it will get mean looking eyes.
Shadowlegend77.

Hint: Sparkly normal Chao:
At the Black Market, buy a white sparkly Egg. Buy two Chao Fruits. Give the Chao Fruits to the sparkly Chao and any kind of non-sparkly adult Chao about the same time. As soon as they have an egg, throw it against the wall to hatch it. Note: This trick will only work rarely. It should be born white with blue patches. It looks even better if you evolve it Dark.
Adam O.

Hint: Platinum Chao:
To get a cheap platinum Chao without a Game Boy Advance, buy a shiny yellow egg and a shiny white egg. Raise them to adults and breed them until you get a shiny green egg. Note: It will be almost lime green. Then, raise it dark.
thewitzkes.

Hint: Rainbow Chao:
Go to Chao Karate and select "Expert". Once you get to the semifinal, you will see a Chao named Rainbow. If you wish to have a Chao like Rainbow, raise a Chao from a blue and yellow egg as a Dark character. Give it red Chaos Drives until its power is at level 4. Next, give your Chao some nuts until it makes a blue cocoon. When the cocoon disappears, it should look like Rainbow.

Hint: Turquoise Chao:
Get an regular egg and hatch it with Tails. Only give it regular fruit, but before that only give it Swim drives. Then, just keep giving it fruit in the Hero Garden. If done correctly, it will start to turn green. Then, get its stamina up to 14 or less. When it evolves it should have greenish arms and flipper like feet, plus green rabbit-like floppy ears on its head.
cjsuner.

Hint: Ultimate Hero or Ultimate Dark Chao:
Raise a neutral Chao to become a Hero or Dark Chao. Have it evolve two times and give it all 21 animals for it to evolve into an Ultimate Hero Chao or Ultimate Dark Chao. This will not work if the Chao dislikes you.
ZacComicMan.

Hint: Ultimate Light Chao:
Raise a neutral Chao without having it evolve into a hero Or a Dark Chao. Instead, give it all 21 animals. Have it evolve two times and it will become an Ultimate Light Chao. This will not work if the Chao dislikes you.
ZacComicMan.

Hint: Unicorn Chao:
Buy a White Egg from the Black Market. Raise it with both Hero and Dark characters. Pick up the egg and nudge it for a while. Note: If you throw the egg against the wall to hatch it, this trick will not work. Once it hatches, feed it coconuts until its stamina reaches level 4. Then, give it two Unicorns to play with. Keep petting it with both Hero and Dark characters so the ball above its head stays the same color, but the Chao gets happier. Soon it will start cocooning. When it gets out, it will be a unicorn Chao. If you abuse the chao in any way this will not work.
Nikhil Sen-Gupta.

Hint: Chaos with items on their head:
Give your Chao a skeleton dog. Then, give your Chao a skull, trash bag, pumpkin, etc. After a little while, a "!" will appear above its head and it will put it on. To take it off, attack or jump on your Chao.

To make a Shadow Chao, keep feeding it Green Chaos Drives and care for it with Dr. Egg-Man.
john lawerence.

Only feed your Chao Red Fruits, and Red Chaos Drives. Do not give your Chao any animals. Your Chao must be a Hero Chao for this to work. Your Chao will have a stem on its head, but when it transforms its sixth time, its head will look like Knuckles.
connor r.

To get a Knuckles Chao, buy a Red egg at the Black Market. Do the various steps to turn it into a Sonic Chao. However, because it is red, it will look like Knuckles. Also, to make it look like the spikes on his hands, feed it a Purple Bear, which gives it claws. Note: Do not feed it two bears or it will also grow ears. To make the spikes larger, only feed, pet, and interact with it as Knuckles.
Gavin Bridge.

Hint: Green Sonic Chao:
Get a blue egg from the Black Market. Give that Chao at least 15 Green Chaos Drives. As Sonic or Shadow, keep petting the Chao. Give that Chao the hog at least two times. You can also get a regular color Chao and give the 15 Green Chaos Drives. Then, when it evolves, spend a lot of time with the Chao as Sonic and it will be blue.
DinoEvan, Snkcc, and sonicmaster.

Hint: Super Sonic Chao:
Raise a Gold Chao from Sonic Advanced or Sonic Adventure 2 Battle with Shadow. Do not give anything to the Chao besides fruits (Hero, Dark, Round, etc.). When your Chao transforms it, will be a Super Sonic Chao.
Phuocanhdinh.

Hint: Hyper Shadow Chao:
Raise a Silver Chao with Shadow. Feed it only fruit and chaos drives (red recommended). When it transforms, it will be a Hyper Shadow Chao.
Phuocanhdinh.

Hint: Tails Chao:
Note: This trick requires a link cable, a Game Boy Advance, Sonic Advance, and a memory card with a saved game from Phantasy Star Online Episode 1 And 2. To get a real Tails Chao, play Phantasy Star Online Episode 1 And 2. Go to the Hunters guild. Select the mission "Fake In Yellow". If it is not there the first time, then play some missions to unlock it. Find the Rappy that used to be a human. Talk to it, and it will make a Telepipe. Enter the Telepipe. You will go to the city. Re-enter the Telepipe. You will see 3 Rappys staring at something. Talk to all three of them and walk over to place they where staring at. A Chao will appear. It will talk to you and give you the Key item "Chao Key". Get off Regol. In the city, by the Hunters guild, you will see a GBA machine similar to the one in Sonic Adventure 2 Battle's Chao Garden. Step on it and transport the data to the Game Boy Advance. A Chao will appear in the Game Boy Advance's Tiny Chao Garden. The Chao's name will be Tails with a ??? under it (its type is unknown). Transport the Chao to the Sonic Adventure 2 Battle Chao Garden. You will now have a Chao that resembles Tails with two tails, his ears, and the hair.
supersonic.

Hint: Tails-like Chao:
Get a Purple Chao and raise it with Eggman until it gets a Dragon head (pet it frequently). Then, give it nothing except Purple Chaos Drives and only feed it five Fruits.
connor r.

Hint: Dark Chao:
Get every animal two times with a Dark character. It can be either be Rouge, Shadow, or Dr. Eggman. Give every animal two times to the Chao, and when his stamina level is at 7, put him on the flowers. The Chao should be in a Chao head-like cocoon and in a few seconds it should hatch into a Dark Chao.
sstark.

If the Chao does not like the fruits it will begin to change gray.
James Hill.

Hint: Crazy Chao:
Have a Dark Chao. When in the Dark Garden give it five Dark Fruits. After that, your Chao will sleep once you whistle. When he gets up, he will have a strange smile and start running around. He will hit other Chaos and knock them down.
Lasrugrat.

Hint: Magic Chao:
When you enter Chao Karate, if you go to Expert you will see a Chao named Magic. First, pet a Chao frequently with Sonic, then get one of each animal and give it to the Chao. Then, get about eight Skeleton Dogs and give it to the Chao. All the animals should be gone. If not, keep giving him the Skeleton Dog then give it lots of Green Chaos Drives. This requires patience -- it should evolve when its level reaches 32. Note. If you leave the Gamecube on overnight, the spike on its head will get longer.
Luis Garcia.

Hint: Chappy Chao:
If you enter Chao Karate expert mode you will see either a Choa named Magic or a Chao named Chappy. To get a Chappy Chao, get a blue spotted egg. The ones from Sonic Advanced are recommended. As Shadow, feed a Chao all normal coconuts (the ones from the neutral Chao Garden) and one of their favorite fruits (Triangle recommended). Make sure it is not asleep for a long period of time. When it evolves, give it a Skeleton Dog, then a Cardboard Box. It should put it on its head.
TaketheStares.

Hint: Happy Chao:
On beginners Chao Karate, the "final" Chao will be named Happy. Use the following trick to create a Chao that resembles Happy. Get an average blue chao, like the ones in the two eggs that you start with. Give it one Skeleton Dog. Buy an Apple for 2,000 rings at the Black Market and give it to the newborn. Then give it rabbit feet and arms. And give it lots of Green Chaos Drives so that it can stand up. Then, go to the fortune teller and use the option to name it yourself. Name it Happy. Bring it to school when they are teaching dances (shake dance, dancing, etc.) and never abuse it. Keep it a neutral Chao and it well look and sometimes act like the real Happy.
the king.

Hint: Ghost Chao:
To make your Chao a ghost, feed it lots of Bats.
astark.

Hint: Transparent Chao:
Breed a Shiny Chao with a Jewel Chao. Jewel chaos are the ones from Sonic Advanced. The normal egg is not a Jewel Chao, but silver and gold Chao eggs are. When the egg hatches, it will be light green and transparent. Try using the egg that costs 5000 rings and the shiny red Chao.
Dogruler28.

Get a Sapphire Chao from Sonic Advance and mate it with a Shiny White Chao. When the new Chao hatches, it will be a Clear Normal Chao. Note: When you change it Dark, it will be a Clear Black Chao, and Hero, it will be a White Clear Chao.

To get a totally transparent Chao, breed a clear Chao (mate a Jewel from Sonic Advance and a Shiny) and a Shiny Lime Green. If you do not get it, reset and try again. You will only be able see its wings, face, and the ball on its head.
Juan Carlos Garza Escamilla.

Mate a Ghost Chao (a Chao that has no legs) and a plain normal Chao. They should have a egg. When you hatch it, it will be a transparent Chao.
Bill Page.

Hint: White Dragon Chao:
Raise a Chao in the Sonic Advance Tiny Chao Garden. Then, raise everything to about 40 and put it in Sonic Adventure 2 Battle. Next, give it only Dragons until every part of it is dragon-like. Then, raise it with a Hero side character and it eventually will evolve into a Hero Chao. Give it mostly Green Chaos Drives. Give it some of the others. Do this until its Run is at 99, Swim is at 94, Fly at 87, Power is at 71, and Stamina is at 69. It should now be able to defeat everything in the Chao Race and Karate, except for the last match in Super Chao Karate.
MP.

Hint: Get higher Chao ranks:
Get the required Animal or Chaos Drive for the type of Chao you want. For example, the Yellow drive or Sea Otter for swim. Then, give them mostly that color of Drive or Animal. Eventually they will evolve into an adult. When this happens, if you gave them mostly yellow for example, the adult Chao will be a swimming type and if your rank in swim was, for example an "A" rank, it will go up to "S". To improve the letter rank in Stamina, make the Chao a normal type.
Kyle Tallaire.

An ability rank are the letters S, A, B, C, D, or E (from best to worse) next to your Chao's ability when you see the doctor in the Health Center in the Chao Kindergarten. To raise the letter up one rank, have your Chao evolve into the type of ability you would like to raise. For example, if the ability rank in flying was A, raise your Chao until it evolves into a Flying Type and the A will turn into an S.
Scott Thomas.

Get a stat increasing item (animals or colored vials). Pick one up and stand directly in front of your Chao, but not so close that he takes it. Drop the item in front of him. He should grab it and get the stats, but the item can be reused.
JackDirt5.

Hint: "S" rank Chao:
Use heart fruits on two Chaos until they want to lay an egg. Repeat with the hatched Chao until you have an "S" ranked Chao at one or more stats. Note: You can speed it up slightly by using more heart fruits at a time.
John MacMillan.

Hint: Stronger and faster Chao:
This trick requires Sonic Advance 2's Tiny Chao Garden and a link cable. When you enter the Tiny Chao Garden, buy a Vitamin (the fruit which that resembles a square apple for 70 rings). Attach the link cable and transfer the Vitamin to the Neutral Chao Garden. Give the Vitamin to a Chao. Keep giving the Chao Vitamins. Enter Chao Karate or Race. In Karate, hits from your Chao will be stronger. In Chao Race, Chao will run faster. Repeat until the Chao's Swim, Fly, Power, and Run is level 40 to 99. This will not raise stamina.
kandy.rayner.

To get a stronger Chao, go to Metal Harbor with Sonic and get the Phoenix. Go to the Chao Garden with Sonic and use the Phoenix on desired Chao. It should raise all the stats except for Stamina. Use the "Unlimited use of animals" trick and your Chao should become strong very quickly.
DABEST12323432.

Hint: Faster Chao leveling:
Note: This trick requires a turbo controller. Walk up to the Chao that you want to level up. Set the turbo feature to B and you will start to pet it. Keep that button pressed and allow the game to idle like that.
james leyba and JXN3993.

Hint: Get two Chaos to breed easily:
Get two heart fruits. Give one to each of the Chaos and flowers will instantly bloom around them. Grab one and put it right next to the other. Note: To breed baby Chao, you need five to ten heart fruits.
CheesyPoofs977.

You must have at least two Chao, one male and the other female. When a Chao has flowers around it, take a Chao and put it in front of it. If it does not work, do the same thing with another Chao. If it works, your Chao will kiss and a song will begin. They will then dance, and an egg will appear.
anthony.

Hint: Rock Chao:
When you pick up your Chao, immediately hold the Analog-stick in one direction while still holding B. You can release B when your Chao starts to rock.
Eleazar Yambao.

Hint: Remove the Chao helmet skull:
Take your Chao and throw it against a wall. It should just come off its head.
Jesse Smith.

Hint: Chao status:
If your Chao has already evolved and has another tear shaped cocoon around it, it is either being reborn or going to die. If the tear shaped cocoon is gray, the Chao is going to die. If the cocoon is pink, your Chao will be reborn and all stats will be divided by 10.
Stuart Converse.

Hint: Fast light or dark Chao:
Hatch an egg in the garden with any desired character. Use a Hero character for a light Chao or a Dark character for a dark Chao.. Pet the Chao so that it becomes either black or white. Keep feeding the Chao nuts. Once its stamina is at level 7 to 15, it will go into a blue cocoon and evolve.
EdCool93.

Hint: Change Chao color to white or black with normal egg:
After your normal egg hatches, decide if you want the Chao to be white or black. If you want it to be black, get either Sonic, Tails, or Knuckles and use that character to abuse your Chao. It will eventually turn black. If you want it to be white, use Rouge, Shadow, or Eggman and abuse it. Note: Chao will be extremely sad, scream, and run.
roadkill.

Hint: Get a Chao Garden through abuse:
If you want a special Chao Garden but do not want to spend a long time petting your Chao, just abuse it. For example, if you want your Chao to be a Hero and get the Hero Garden, use Dr. Eggman, Shadow, or Rouge in the Chao Garden and abuse your Chao with that character. If you attack a Chao enough times with a character, the Chao will become the opposite of what your character is. In the example, your Chao will turn very white and become a Hero. If you abuse your Chao with Sonic, Tails, or Knuckles, it will turn black and become a dark Chao. Note: It will take awhile for them to cocoon themselves.
Scott Burbank.

Hint: Bury your Chao or items:
In the Dark Garden, in front of the fence that is on the right of the tree that does not grow fruits, place items (including Chao) as close as you can right in the center of the fence. The item or Chao should now be buried.
Brett.

Hint: Open Chao egg easily:
Throw a Chao egg against a wall.
Jim Pelyhes.

Hint: Unlimited eggs:
Note: This trick requires two memory cards. On memory card two, you must have less than the required amount of blocks. Play the first level and get the Chao box when you finish the level. Go to the Chao Garden. You will see two eggs. You can hatch them if desired. Walk over to the computer and trade them to memory card one. After that, select a stage and pick the Chao Garden again. It will say the same thing as before, and you will have two new eggs.
jojo_the_monkey.

Hint: Wake up Chao:
If you go to the Chao Garden and your Chao is asleep, pick it up and bring it to the doctor within fifteen seconds from picking it up. Get the doctor to examine him. When you get back, he will be alert.
Scorp7225.

Hint: Keep Chao from going in the water:
In the Hero Garden, put a Chao behind the first fallen pillar to the left where you entered. It should stay there because it will have a question mark above its head, turn around, and keep on thinking and turning around. This is very useful if you have Chaos that cannot swim and you want to leave the game on overnight. Note: This trick will not work if you put the Chao too far back from the pillar. You must put the Chao behind it so that it is almost touching the pillar. It works best if the Chao is in the center.
DarkDragon0009.

Hint: Pet multiple Chao at once:
Raise five Chao that will go to you when you whistle. Make sure that they are all awake. Whistle and when they arrive, press Y until it says "Pet". You should be petting all five Chao, but can pet up to eight at the same time.
Chao Raisers.

Hint: Chao life cycle:

Be nice -> Cocoon (pink) -> Reborn
Child -> Cocoon (blue) -> adult ->
Abuse it always -> Cocoon(gray) -> Dies

If the Chao is an adult and you treat it nicely, it will remember you, turn into a pink cocoon, and appear as an egg. The Chao starts off at level 00 again, but still has its stats. However, if you treat your Chao badly as an adult, it will become a gray cocoon and disappear forever.
Kyle Lowery.

Hint: Raising Chao stats:
This trick requires 15,000 rings for Chao fruit. Give it only free nuts and whatever stat you would like. After that stat is over 5 to 10, give it a strict diet of Chao fruit. When it evolves, bring it to the doctor and check the stats. It will have an "S" under the stat you worked on and say that it is either a Flying, Swimming, Running, or Flying type.
the king.

Hint: Chao aging:
Chaos age about one year every four hours you spend in the garden that they are in. If you were in a garden for 24 hours, every chao would have become a baby for its second time (if it was already an adult).
aj.

Hint: Chao that never die:
This trick requires two or more Gardens. When your Chao begin to transform, if it has a gray cocoon, exit the Garden, not the Chao World, then enter again. Look for your Chao, and if it has a pink cocoon, then it is safe. If not, reenter and look for your Chao quickly, and choose it (try this with Sonic or Shadow) and put it down. Then, pet it faster until your Chao has a heart when you pick it. Put it again until it creates a pink cocoon. If it still has a gray cocoon, reenter the Garden and pick it quickly. Exit that garden with your Chao in hand and enter another garden. Put it down and pet it, and it will create a pink cocoon. If this does not work, keep trying the last step until it does. Note: This does not work all the time, so keep trying.
jorge de jesus pedroza cantu.

If your Chao forms a gray cocoon, reset the game and put your Chao in Kindergarten. Then, go to the Chao Garden and get all of the coconuts in one place. Next, go to the Hero Garden and get all the coconuts in one place there as well. Then, get you Chao, go to the Chao Garden, and put it down where all the coconuts are locted. Quickly give it all the coconuts. Then, pick it up and bring it to the Hero Garden. Make it eat the coconuts there, then wait. It will make a pink cocoon. Note: This will not work if your Chao dislikes you.
Chao505.

Hint: Name Chao yourself:
Go to the fortune teller with your Chao. When she offers a name for your Chao and asks whether you like it, answer "No". She will make another suggestion. Answer "No" again. She will then ask if you would like to name the Chao yourself. Answer "Yes".
V.L..

Hint: Delete animal characteristics from Chao:
If you have a Chao with strange animal characteristics, simply give it a few Skeleton Dogs. Your Chao will return to normal. If you want to give it an animal and you do not like the outcome, repeat the process again.
Carl Nafarrete and Patrick Nafarrete.

Hint: Regular teenage Chao:
To keep your Chao from becoming a Dark or Hero Chao before it evolves, alternate between Hero and dark Characters every visit. If the colors of your chao start to change, simply pet the Chao with the other side until it returns to normal.
CTLinde.

Hint: Unlimited Chaos:
Use a link cable and connect a Game Boy Advance to the Gamecube. Get Sonic Advance and enter the Tiny Chao Garden. Keep transferring Chaos to the big Chao Garden for a free unlimited supply.
cher hung.

Hint: Faster Chao growth:
Transfer the Chao that you want to level up to the Tiny Chao Garden in Sonic Advance. Keep giving it fruits until it is at a good enough level and it will grow faster than in Sonic Adventure 2 Battle. Note: Your Chao will not age in the Tiny Chao Garden.
Michael Sheffield.

Hint: Avoid Chao race losses:
If you are racing your Chao and know you will lose, press Start and select "Exit" and it will not be recorded as a loss.

Hint: Waking Chao up:
Sleeping Chao are annoying because you cannot feed them. To wake them up, stand next to it and whistle. You do not have to anger them by picking them up during a little nap.
cher hung.

Hint: Gliding Chao:
In the Chao Garden, pick up your Chao and carry it on top on the entrance of Chao Karate and Race. Leave your Chao there, then go in front of the water, facing your Chao that is on top. Whistle, and it will fall and glide towards you.
GERARDO ACEVEDO.

Hint: Not worrying about Chao aging:
Note: This trick requires a Game Boy Advance, Sonic Advance, and a link cable. If you raise your Chao on the Game Boy Advance, you do not have to worry about it aging. If you are trying to save time, the Chao does not age at all. This is a good way to level up your Chao if it is at its third life (two transformations).
projectshadow316.

Hint: Chao sleeping sitting up:
Let a Chao run up to get a fruit. As soon as you hear the sound of it grabbing the fruit, take the fruit away. The Chao should still be eating and after a while a fruit will appear.
PLHunst.

Hint: Chao in a cage:
In the Dark Garden, keep throwing a Chao at the cage and it will eventually go in.
Gcnthunderbird.

Alternately, jump on the tombstone to the left, then jump into the cage from there. To put a Chao in it, you have to be at the very edge of the cage.
Brian Young and james ranado.

Go into the Dark Chao garden as Tails. Pick up a Chao. Next, jump up on to the gravestone by the cage. Jump into it holding the Chao. Place the Chao down. It should sty in the cage for awhile. This may require a few attempts. If you try to push it into the cage more than it is, it has a higher risk of falling off. Note: You should try this with a Dark Chao or a Chao that does not like you very much.

Hint: Alternate view in Chao Lobby:
Enter the Hero Garden then go back out. Walk off the side and control your fall so it looks like you are under the entrance when you land. You can go to the Kindergarten and Dark Garden, but the camera will remain on top of the stairs.
chillpaw.

Hint: Land in cage:
As Shadow, enter the Dark Garden and go to the big tree on the right. A cage is hanging on the side that is facing the pool of blood. Jump up and you will land inside it.
Jimmy and Bradley.

Hint: Eggman in a cage:
Go to the Dark Chao Garden with Eggman and stand on the tomb near the small cage hanging on a tree. From the tomb, jump into the cage and Eggman will be caged. If you then jump, his head will be a skull.
X-Yoshi.

Hint: Quick Chao transformation:
Keep petting your Chao and it will eventually transform.
cher hung.

To do this trick, you must not care if you abuse your Chao. To get a Hero Chao, abuse your Chao with a Villain. To get a Dark Chao abuse, your Chao with a Hero. You can tell if your Chao is turning good if it is mostly white and has a blue ball over its head. You will know its turning bad when it is black and most likely has a red collar or a point on its tail. Get the stamina to level 7. Note: If you are transforming a different color Chao (for example, blue, red, shiny blue), its body may not change color, so look at its wings (bat or not), tail (pointed or not), and the ball (red or blue) on its head.
Seamard.

For your Chao to evolve fairly quickly, you must feed it Coconuts until its stamina is above level 10. For a Dark Chao or Hero or Neutral Chao with their head on fire, just give them only Half Fishes. For a Chao with a drill-like head, give it lots of Gorillas and Tigers. For a Dark Jester Chao, give it mostly Peacocks and Condors. For a Shark Chao, give it only Sea Otters, Half Fishes, and Seals. For a Chao with green streaks such as Shadow, mostly raise it on Cheetahs and Unicorns. After its head starts to part differently, feed it until its stamina is at level 11 or higher. Note: If you are looking for a Chao that is good in races, raise a Dark Running Chao with mostly Cheetahs and Unicorns. For a Chao that is good in Power Karate, raise a Chao heavily on Gorillas and Tigers. Robotnik's first level, Iron Gate, is the best place to raise a Power Chao.
Brent Bigelow and mewtwo-master2002.

If you have the Dark Chao Garden, throw a newly hatched Chao into the blood-like water. Watch it for a while and it will transform. If your Chao comes out, throw it back in.
dragonfly_ryder.xl.

Evolve at least one Chao to make it a hero (in the Hero Garden).Then, take a "baby Chao" that has only a few stats (for example, level 1 for swim, level 3 for flying, level 0 for power) and has a hearty appetite (or is hungry). Pick up the Chao and bring it to the Hero Garden. The white pillar on the left hand side of the garden is knocked down. Take the chao and put it directly next to the pillar on the side that is facing the rock wall. If you placed it correctly, it cannot leave that space, can only be behind the pillar. Get a fruit and feed it to the hungry Chao. If it eats it all, it may evolve. This may not happen, and the process may need to be repeated. Make sure you hear the "grum grum" sound that they make when they are hungry and eating a fruit. Watch and they might evolve. Your Chao may need to be out of its egg for a little while before you do this.

Hint: Transformation signs:
The following signs indicate that your Chao is close to transforming. If you have a Dark Chao, it will sleep a lot and have a spear-like tail. If you have a Hero Chao, it turns white (if not already white).
Tiana Chaos Expert.

Hint: Hidden Chao transportation:
Walk up to the Chao Kindergarten when an item is in your hands and your Chao is at a classroom. When selecting "Pick-Up Chao", if you still have the item in your hands, your Chao will not be in your hands. It will be in the Chao Garden (if your cocoon has hatched -- go to either the Hero or Dark garden).
RKB22NOW.

Hint: Hatching your Chao:
If you are having trouble hatching your Chao, hold it for about ten seconds then whistle. It should pop out.
werewolf.

For a quick hatching Chao, pick up a Chao egg and throw it against the wall. Note: This may affect your Chao's appearance.
Lilc456.

If you want a Chao egg to hatch faster, rock it for about three to five seconds, then put it down and whistle. Note: This may affect the Chao's smiles.
Raven Wolf.

Hint: Raise Chao's stamina:
To raise your Chao's stamina easily, when you feed your Chao a fruit, stand behind it. When your Chao throws it, you can pick it up and bring it back. You can do this repeatedly.
SkatinJuggalo99.

Use the following trick to get a powerful, young Chao. Either use Chaos Drives, Small Animals, or Chao Fruits. When you raise them, only go in the Chao Garden when you want to raise the Chao and not to play with it. If you still want to play with your other Chaos, put the one you are raising in a separate garden, all by itself. By following this, it is possible to have a two year old Chao with all its stats at level 99 (the highest level).
VideoGamerX01.

Hint: Getting your Chao to like you more:
Treat your Chao with respect. Learn your Chao's personality, favorite food, and how well it does things. Give it a lot of Chaos Drives and any small animals. Let it compete in races and karate matches frequently. This should make your Chao your best friend.
Clayton DuBoce.

Hint: Double Chao petting:
In any Chao garden, put two Chaos next to each other. Start petting one of them and they will both have hearts on their head.
Trevor Heckenast.

Hint: Chaos Drive colors:
Scott Thomas.

Yellow: Swim
Green: Run
Red: Power
Purple: Fly

Hint: Reuse Chaos Drive or animal:
Get a Chaos Drive or animal and go to your garden. Take either one and bring it to your Chao, but do not give it to them. Drop it directly in front of them, very close. They will get the points but they will leave it there to use over and over. Try giving it fruit, then do it so its not moving around.
Mark.

Note: This is very difficult to do. Make sure that you have your Chao secure (do not let it move). Back up slightly away from the Chao you selected and do not let it get the Chao Drive. Put it down and the Chao should not absorb it. Once the Chao gets it, it will then bounce further back.
Quiksilver88guy.

Fill your Chaos Drive slots with small animals. Go to the Hero Garden as Sonic and feed the animals to a Chao. Wait three minutes and move around randomly, while still in the garden. Uou can feed the animals to a Chao again. Note: This works best with Bats.
Frank Phillips.

Hint: Easy Chaos Drives:
There are two very good places to get easy Chaos Drives for your Chao, The first is Tails' level, "Prison Lane". You can get through this level very easily, and it has a lot of enemies for drives. You can use this level to get a Chao more acquainted with Sonic, Tails or Knuckles by selecting them when entering the Chao Garden after collecting the desired drives, then exiting the level. The second location is Eggman's level, "Iron Gate". Use the same procedure as above for Shadow, Rouge or Eggman.
manderlay.

Play the "Mission Street" level. There are plenty of Chao drives there that are easy to get. Most of the time they are of the same type. It might take awhile to find the desired drive for your Chao.

Hint: Unlimited Chaos Drives/Animals:
This trick is used to get several Chaos Drives or Animals of the same type. Go to the stage selection screen and choose the second mission (collect 100 Rings) with any character. Collect one ring at the start of the level. Collecting more is not necessary; you must have less than 100 Rings. If you are looking for Chao Drives, kill the enemies searching for the desired color. Leave one enemy at the end of the level. Let it hit you. You will lose all of your Rings. Pick up a Ring and kill the enemy. At the end of the level there will be a Ring that reads "Back". When you touch this Ring, you will be back at the start of the level, but you will still have your Chao Drives. Repeat this until your inventory is full of the desired Chaos Drive. Note: The "Back" ring for Knuckles' and Rouge's stages is at the starting point. If you are looking for Animals, go through the level, searching for the desired Animal (avoiding enemies if possible, if you are not also looking for Chaos Drives). Once you find the Animals you want, remember where they are located. Then, let an enemy hit you. This causes you to lose your Rings. Pick up a Ring and kill the enemy. At the end of the level (or starting point for Knuckles and Rouge) there will be a ring that reads "Back". When you touch this ring, you will start the level over, but still have your Animals. Repeat this until your inventory is full of the desired Animal. Note: This trick works best in Knuckles' or Rouge's level.
Typo Number 9.

Have the desired Chao to stand still. Grab a Chaos Drive. Do not give to him. Stand far away enough so that if you dropped it, the Chaos Drive would land in between you and the Chao. Drop it, and he should take it and shoot it back up. If this did not work, grab it again and keep getting closer and dropping it until he takes it and shoots it back up.
XHAXCHEATER.

Hint: Make a Chao follow you:
If a Chao is in its flowers, pick it up and it will follow you for a while. Also, if you whistle now, it comes to you.

Jmc4akahp.

Buy a box, bag, pot, or any other expensive item in the Kindergarten. Then, save the Chao data, then re-enter Chao World. Sell the item, and when the "ca-ching" noise ends, reset your Gamecube. When you enter Chao World. you will have both the item and the rings. Note: You have to save the Chao data after you buy the item, but before you sell it. This works best if you sell expensive items, such as the 50,000 ring gray mask.

Get the Light Dash ability and go to Metal Harbor. Whenever the large rows of rings are ahead of you, use the Light Dash move. This is a very fast and easy way to get rings.
Logan.

Get something that sells for a lot of rings. If you do not have many, get an old pot and use it for this trick. If you have the time, get a Shiny Egg Shell (recommended). You cannot sell the egg -- you can only sell the shell. Go to the Black Market with the egg and you sell it. then. Exit out of the Black Market and while still in the Kindergarten, hold B + Start + X for about two seconds to reset your game (without saving the Chao data but saving the game data). Since the Chao data did not save, the game believes the egg is still there, while the saved game data records that you sold the egg for a couple thousand rings. You will get the egg and the money back. Repeat this (sell the shell, reset game, then go back to the garden) to end up with lots of rings.

Go to the Black Market and buy an item that costs a decent amount of money. It must be an item that you can resell. Put it in any Chao Garden, then leave the Chao Garden, which saves the game. Reenter the Chao Garden, get the item, then sell it at the Black Market. As soon as you sell it, press the restart button. Repeat this as needed. The item will not disappear, but your rings will keep increasing.

Blaine Walters.

Unlock the racing game (just route 101 or 280). If you got a "D" or "E" rank on the first mission, it would be easier for you to do mission 2 (get at least 100 rings). If you got "A", "B", or "C" rank, just do mission 1 (get at least 200 rings and also get 2 extra lives).
