Sora and company's very first stop is Wonderland, where they start things off by falling down a rabbit hole. Upon landing, they notice a peculiar rabbit in a waistcoat, seemingly in a hurry. They immediately give chase, stumbling upon a tiny room with a sentient doorknob. There, Sora learns that he and the others can follow the rabbit with a shrinking potion.
After shrinking and following the rabbit, Sora and company stumble upon a trial where a girl, Alice, has been accused for supposedly stealing the heart of the Queen of Hearts. Despite Donald and Goofy refusing to meddle in the affairs of other worlds, Sora interrupts the trial, saying that they know who the real culprits are: the Heartless. Alice is imprisoned, but the Queen orders Sora and company to get her enough evidence to prove Alice's innocence.
With the help of the mysterious Cheshire Cat, Sora and company manage to retrieve enough evidence of the Heartless' crimes to present to the Queen. Despite the evidence presented, the Queen hoists Alice's cage with a Crank Tower and sets her minions upon the trio. Sora and company destroy the tower, only to discover that Alice has vanished. They proceed to run through Wonderland and search every nook and cranny for Alice's whereabouts and eventually return to the Bizarre Room, where they run into the Trickmaster, which they promptly defeat.
With the Trickmaster's defeat, the Doorknob complains about the racket, only to reveal that his mouth is a keyhole. Instinctively, Sora's Keyblade appears and seals it, much to his surprise. With that done, the Cheshire Cat appears and explains that Alice has disappeared from the world entirely...
Tropes:
- Alien Non-Interference Clause: Donald and Goofy abide by the rule of not meddling in the affairs of other worlds. Sora, being who he is, ends up breaking this rule to save Alice.
- All for Nothing: It is possible to select evidence claiming Donald and Goofy as the culprits. If that happens, they'll be put in cages before the battle against the Queen's minions, although Sora can bust them out.
- Chest Monster: Sora can stumble upon the Mad Hatter's tea party. Most of the seats he can sit in can yield prizes such as MP and HP orbs but sit in the wrong seat and Heartless will appear.
- Gravity Screw: The Bizarre Room. It's got multiple entrances and exits, each of which will put Sora and company in different areas of gravity.
- Incredible Shrinking Man: The trio ends up getting into Wonderland this way, using a potion to shrink down. Curiously, they start off already shrunk if they show up in the Queen's courtyard via save point.
- Kangaroo Court: The Queen of Hearts accuses Alice of attempting to steal her heart, using only her own word as proof. When Sora, Donald, and Goofy gather the evidence to prove Alice's innocence, the queen forces them to choose one box of evidence to present. If Sora succeeds in proving it was the Heartless, the Queen gets angry about being proven wrong and orders them all executed. If Sora chooses a box that implicates his friends, she will accuse them of being the culprit and order them executed.
