After you beat the game and come back to your 2-D self, go to level 3-4, the one with Francis's (The Chameleon) castle. Go to the room where you fought Francis. He is taking a picture of a Pixi that looks like Tippi. Francis will offer it to you for...free...no actually 999 coins! After you buy the look a like Tippi, it will act like Tippi and give information to you in every area.
