Kingdom Hearts II/100 Acre Wood

Though this world is optional, completing it is recommended to complete Jiminy's Journal. The first visit will happen in the main story. All subsequent visits are unlocked by collecting torn pages.

First visit
The first visit occurs when Merlin summons Sora back to Hollow Bastion. After the scene, approach Donald and use the reaction command to enter the book. Approach the pop-up nearby to enter the 100 Acre Wood, particularly "Pooh Bears Howse". Begin by looking behind the house for some treasures: an AP Boost, a Mythril Stone, and a 100 Acre Wood Map. Speak to Pooh to trigger a scene, only for Sora to be kicked out of the book. Battle the Shadows and Soldiers outside and Sora will return to the book only to find that its been emptied. Return to Pooh's house to find that Pooh has forgotten Sora. With no other choice but to leave, you'll find yourself back in Merlin's house. After another short scene, you'll obtain the Baseball Charm, allowing you to summon Chicken Little. You can now leave the world in search of the torn pages.
