Wonderland

Wonderland is an early world from Kingdom Hearts and Kingdom Hearts: Chain of Memories. It is based on Walt Disney's 1951 feature film Alice in Wonderland. Bearing a close resemblance to the Wonderland seen in the movie it is based on, this world is nonsensical 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.

Setting
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, called the Bizarre Room, has a table which has "Eat Me" or "Drink Me" bottles which cause the consumed to grow or shrink in size. The Rabbit's furniture can be folded up into the walls or flattened to change the room's structure, reveal treasures, or open new doors. Different doors into the Bizarre Room cause the gravity to shift, allowing you to explore the walls and ceiling of the room.

Entering the door behind the bed leads to the Queen's Court, outside of her castle in a hedge maze. Here she runs her pointless court sessions, and is where the boss battle against the Card Soldiers is fought. The Lotus Forest through the opening to the left is a large wood full of giant mushrooms and flowers which ask for potions and other items; one flower can be given a potion to make Sora grow larger. Various items that can be manipulated, depending on Sora's size, such as the stump, the boulder, and the tree in the center of the wood; knocking the nut from the tree and consuming it returns Sora to a shrunken state.

Finally, there is a small area that is the location of the Tea Party Garden, where the Mad Hatter and March Hare's tea party is laid out; the hosts themselves are imprisoned in a portrait on the wall, but sitting the in chairs around the table can grant prizes or penalties.

Kingdom Hearts
Wonderland is the first world Sora, Donald and Goofy travel to together. They arrive just in time to witness poor Alice be put on trial for apparently trying to steal the Queen of Hearts's heart. Alice is sentenced to beheading, but Sora intervenes, promising the tyrannical queen he shall bring evidence to prove Alice is innocent. While searching for evidence, Sora is helped by the Cheshire Cat who gives him the Blizzard element. 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 and lighting candles in the upside-down Bizzare Room, they return to the normal Bizzare Room and face off against the Trickmaster Heartless, which they destroy. They then discover the world's Keyhole in the sleeping Doorknob's mouth and seal it. Later we find out that Alice was kidnapped, because she was a Princess of Heart. If you return after learning the White Trinity Mark, you can get Wonderland's Keyblade, Lady Luck.

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

Trivia

 * Wonderland is one (and the first you encounter) of the three Disney-based worlds in which you never fight alongside a character from the Disney production it's based off of (either as a party member or an assist character). This is because there is no protagonist suitable for combat, as the only Alice in Wonderland protagonist is Alice herself, who is both incapable of fighting and a Princess of Heart.
