At the start of a new game, go to the right until you reach a teddy bear. Now face the wall and jump in that direction. Walk to the next room just to the right of where you are, which will lead you down to a small room. Jump to access a platform, and use this platform to access a playroom where you can turn cheat mode on. Now enter any of the following "Codes" during gameplay using Controller Two:
