Sora and the gang appear in this new land of, well… wonder. He and his compatriots are taken by surprise by a well-known rabbit with a severe lack of punctuality. The White Rabbit is late, for some trial apparently, and runs off in the direction you need to go. Battle a few Heartless en route to the only door, located to the left in this room.
After using the correct number Card to unlock the door, take on whatever Heartless the Map Card instigates, then smash some trees and pummel some presents to obtain more Moogle Points and health orbs. The enemies in the world have stronger damage and are harder to dispatch, however you will gain more experience that you can wave a stick at.
Once you proceed through the door, you will be in a room with three doors leading in different directions. The Card to access the door to your right is not in your possession, so this narrows your choices down to the other two. The door in the center provides access to another room that you may enter if you wish, however this way ends abruptly because you will most likely not have the Key to Rewards Card yet to access the special room from there. That narrows it down to the door to your left. Enter this room and find two other doors leading in different directions. The numbered door leads to another room that will be blocked for Sora for the time being, as you do not have the Map Card to open it at this point. For now, the only way to proceed is through the crown door.
This path leads to a sobering sight. You stumble upon a horrified Alice who is about to be put to death by the Queen of Hearts. As one may predict, Sora demands a stay of execution, thus dragging you along for an easy and quite laughable battle with an Army of Cards.
Boss Battle: Army of Cards
While this is technically more of a mid-level boss, it is nothing too difficult to overcome. These Cards are a bit more difficult to defeat than your normal Heartless in that they have quite a bit more HP and defense, so take care and heal when you can. That being said, they are not a major challenge. By this point you should have a pretty decent arsenal of Magic and Summon Cards to help deal with these enemies, so use them as freely as you wish to defeat all the Cards. There are three waves of Cards and each wave has more and more Cards, intent on lopping off your head. The Queen is a bit abrasive in that way.
Just attack, use Summon and Magic Cards, and heal occasionally and the fight will be yours. After the fight, you gain the Card Soldier Enemy Card.
Turns out that while you were defending Alice’s honor, she was able to make her escape. The Queen of Hearts is none too pleased with you dispatching so many of her finest soldiers, and sends another deck of Cards after you. Sometimes, true courage is knowing when to run. A short cutscene shows Sora, Donald, and Goofy sprinting away, with Cards giving chase.
Once outside, you are in the giant courtyard from before. Head through the door to your left and into the next area. This is the room from before with the three doors. This time take the right path, since you now have the correct Map Card to enter here. Use it and proceed through to the next room. Alice is there and seems grateful for what Sora did for her.
While Sora is speaking with Alice, the Cheshire Cat appears. He claims that the Queen will hunt you down until she inevitably catches you and then will undoubtedly lop off your head for everything you have done. The best defense is a good offense it seems, and your only option now is to take the fight to the Queen of Hearts herself. After the rather enlightening conversation with the Cheshire Cat, you receive the Key to Truth Card. A boss battle is coming and there is no way around it. From here head through the door to your right. In the next room, take the next door on your right. Once in the next area, take the door straight ahead of you. Lastly, climb the ladder to your left to access the crown door.
Boss Battle: Trickmaster
The master trick to Trickmaster is to lock on to him, since the area that you lock on to is the only area in which he will receive damage. This boss has an affinity for fire. He will use that element all over the place, so the Dodge Roll will be your best friend through this fight. His first attack is a lot like Sora’s fire attack, so dodging it will be moderately easy. Next, Trickmaster will walk across the room. This may seem odd, but once you catch a glimpse of his razor blades for feet, you will understand. Simply roll out of the way to avoid his sharpened shoes.
The best chance for attack is when Trickmaster gets ready to perform his other powerful two-armed attack where he twirls his staff and bends down for the assault. He will take a break and ready himself, which grants you ample time to run up on him, Keyblade swinging.
After this master of tricks falls for the last time, Sora is given the Trickmaster Card and an exit from Wonderland.
Back in Castle Oblivion, you learn a bit about a blonde girl named Naminé, who Sora suspects is his friend from childhood. The reason she is prying into Sora’s head now is a mystery. It must be Castle Oblivion’s effect on the mind. That being said, there is not much you can do about it for now. While on the fifth floor Entrance Hall, save your progress, and then continue to the door in the back of the room to be transported to Monstro, the next world on our list.
