Wonderland

Wonderland is an early world from Kingdom Hearts and Kingdom Hearts: Chain of Memories. It is based on Walt Disney's Alice in Wonderland. The boss of Wonderland is the Trickmaster. Bearing a close resemblance to the Wonderland seen in the animated film it is based on, this world is nonsenscial and bizarre in its own way. Houses that have foldable furniture, a tea party without any guests and a forest of giant flowers are just some of the odd things found here. The world is ruled by the stroppy Queen of Hearts, and her card-like soldiers. Notable residents include Alice, the Queen of Hearts, the White Rabbit, the Cheshire Cat, the Doorknob (which holds the Keyhole) and the Mad Hatter and March Hare (who seem to be trapped inside a portrait).

Kingdom Hearts
Wonderland is the first world Sora, Donald and Goofy travel too together. They arrive just in time to witness poor Alice be put on trial for apparantely trying to steal the Queen's heart. She is sentenced to beheading, but Sora intervenes, promising the tyrannical queen he shall bring evidence to prove Alice is innocent. Upon returning with evidence, the Queen locks Alice in a cage and unleashes her card minions upon Sora, but he defeats them. Sora rushes to save Alice but discovers her cage is empty. Sora and his friends rush off to find Alice but after a confusing search, they are shrunk and face off against a Trickmaster Heartless, which they destroy. They then discover the world's Keyhole in the sleeping Doorknob's mouth and seal it. Alice was actually kidnapped, because she was a Princess of Heart.

Chain of Memories
The characters of Wonderland return in the form of memories of Sora's, during his time in Castle Oblivion.

Kingdom Hearts: 358/2 Days
A screenshot of Kingdom Hearts 358/2 Days shows Roxas, Axel, Xigbar, and Saïx battling Heartless in multiplayer mode in the Lotus Forest, which is a location in Wonderland.

World Structure
Wonderland is an odd world full of bizarre places. Sora, Donald and Goofy fall or "float" down a rabbit hole into the house of the White Rabbit, which is a large room with a hall. The main room has a table which has "Eat Me" or "Drink Me" bottles which cause the consumed to grow or shrink in size. Interestingly, the Rabbit's furniture can be made 2D and folded up into the walls.

The Queen's Court is outside her castle in a hedgemaze. Here she runs pointless court sessions, deciding the punishment before verdict. Her card guards attack on her command. The Lotus Forest is a large wood full of giant mushrooms and flowers which asks for food. There is also a small area where a tea party is laid out, presumably by the Mad Hatter and March Hare, who are imprisoned in a portrait on the wall.
