When you find the fourth torn page, you go to a forest-based section of the world. At first, you find Tigger and Roo bouncing on a teeter-totter, and when you talk to them they start a mini-game, Tigger's Giant Pot.
The next game is the main mini-game in the Giant Pot Area. You can only play it once you complete the Bouncing mini-game.
In Tigger's Giant Pot, the aim of this game is to jump on the same tree stumps in the same order that Tigger and Roo do, without falling off.
In Giant Pot Area, Tigger goes into the giant pot in the middle of the area. Sora's job is to hit the nuts that Tigger throws out of the pot back at it to shatter the pot. If you fall off of the stump you are on, you will lose the game unless you manage to hit the nut and jump back on the stump.
