Shrek: Extra Large

Inside The Nintendo Gamecube codes:
When you defeat Merlin and unlock the codes in the pause menu, you can go inside the Nintendo Gamecube through these places:
tbuno tlra, vyprh paeosugy, Christian, and joshua addesi.

Prince's Castle: Go inside the window and try to get back, but miss.

Creepy Crpyt: Go on the church, then press R and L a lot to the north.

Mother Goose Land: Go to the farm and press R and L to any direction.

Molasses Sewers: Go to where Frankendrop is located. Go up to the bell then go right. Hump and press L hard and R light repeatedly to go in the inside the Gamecube.

Hint: Defeating Merlin:
Kick all of Merlin's soldiers into the T.N.T. pit. Then, use all of the T.N.T.s to burn down the doors. When you reach Merlin, super punch all of the spells, but do not super punch the T.N.T. Grab the T.N.T., go near the crystal ball, and flame the T.N.T. Go up the stairs and flame Merlin three times. Then, go down and flame Merlin two times. If you defeat Merlin, you will hear him say ''Ohh. never saw that coming''.
Christian.

Hint: Finding the last egg:
The last egg is located in the same place where found find Little Red's basket in the falls.
Christian.

Hint: Three horsemen chase the Big Bad Wolf:
In Mother Goose Land, put any of the three horsemen near the Big Bad Wolf. They will chase the wolf instead of you. Unless you get very close to them, they will not attack you. This can be helpful in completing a few of the quests in Mother Goose Land. For example, if the wolf is getting beat down when you must get the sheep he cannot kick them out of the fence.

Hint: Crossing the bridge:
Get the red pepper when you are in the mine in 'The Enchanted Forest level. When you get the red pepper, go in the river, fart, and blow up the fart near the large brown tree. Be careful -- stay out the ground's shadow or you will bump your head. Kick or punch the tree to make a bridge. Make the kids follow you across the tree, and put them in the gingerbread house.
Christian.

Hint: Defeating Frankendrop:
Find Frankendrop inside the ring. Around him there is a smaller Frankendrop. Do not jump into the ring. Instead, charge your Superpunch by holding X (wait until your fist is red). Before you release X, jump with A and press the Analog-stick Up. Try this out a few times until you get it correct. Approach Frankendrop while you are still outside the ring and punch him with your Superpunch technique. If done correctly, Frankendrop should be knocked out (on the floor with stars around his head). Kick (B) or punch (X) Frankendrop until he is out of the ring. Do this two more times (a total of three times) to defeat Frankendrop.

Hint: Defeating the Ice Queen:
Enter the pipe that leads to the Queen's lair. She will start shooting things at you. Keep going forward. You will see a chili pepper. Get it and jump to the platform where the Queen is located. Expel gas in the Queen's face. Blow up your gas with the pepper. After you get notified that you hit the Queen (by an icon in the corner of your screen), run back to the pipe that you entered in. Replenish your health, etc. Kick any of the things that the Queen threw at you that may have gone in the pipe. Then go back and attack the Queen two more times, going back in the tube to replenish or to take a break between each attack. The Queen's things cannot reach you there. Note: If you fall while you are attacking the Queen, she will not shoot most of the time. Just kick the things to get rid of them. Also, the Queen shoots things at you if she can see you.

Glitch: Fall:
This works best after you have returned the Workers to their Stations. In the Molasses Sewers, there is a section that has a pipe that shoots vapor vertically. At the very end of that section is a faucet with brown stuff coming out of it. There is no way out except for two pipes on either side. Around the pipe that shoots vapor is a Worker Station (gray with a red button). Next to it is a wall. Jump between the Station and the wall and you should see Shrek with his mouth open and his hands in the air.

Glitch: Headless Shrek:
In the Sweetsville Park, jump down the waterfall where you begin. Face the waterfall and press R. If done correctly, it will appear that you have a headless Shrek.
