100 Acre Wood, also written as Hundred Acre Wood, is an optional world based on the fictional locale of author A. A. Milne and Disney's twenty-second animated feature, The Many Adventures of Winnie the Pooh. It is special in both Kinect Mickey's Disneyland Adventures and Kinect Mickey's Disneyland Adventures II as a world within a world, because it is entered through a book in Traverse Town and Hollow Bastion/Radiant Garden, respectively. The world is contained within a magical book that Merlin keeps with him, and as Mickey collects Honey, the lost areas of the world are revealed as the story is retold.
When Mickey enters the book, he lands on a version of the flat map of the 100 Acre Wood. Classic locations such as Winnie the Pooh and Piglet's House are accessible, as well as the Muddy Path and Spooky Cave, making this world one of very few to show a change of day. Each location usually harbors a mini-game with prizes which help Mickey, Tidus, and Riku on their journey, although Mickey is the only one that goes into this world.
It is doubtful there is a ruler of this world. Strangely, throughout the entire series so far, not one Heartless has appeared in this world. Because of this downplay of violence, Sora's "Attack" command is changed to "Hit" while in this world.
In Kinect Lumiere, Cogsworth and Fifi's Disneyland Adventures: Birth by Sleep, the 100 Acre Wood is a world that is only available for play through the Command Board, rather than a complete world.
