One night when Mickey is fast asleep, he falls into a dream where a mischievous ghost traps a dream vision of himself inside a magic mirror. Stuck in an alternate universe that strangely resembles his own house, Mickey yearns to get back through the mirror to his own house and his own bed in order to wake up from this dreamlike state, however the ghost destroys the mirror and the pieces shrink and fly off to different areas around the house which turns the magic mirror into a normal mirror. The player must direct Mickey to outwit and pull gags in order to get past enemies, obstacles, and the aforementioned ghost and recover the twelve broken mirror pieces he needs to go home again and search for twelve magic stars (needed to pull gags) and items needed to help him throughout his quest. Whenever he finds a piece, it will fly back to the mirror and put itself back in place. After repairing the mirror, he prepares to leave but the ghost stops him revealing that it only brought him here so he can have someone to play with. The player could either chose to stay or go. Choosing to stay will make the ghost run off, leaving Mickey stuck in the alternate world until he reenters the mirror room where the player can choose to stay or leave again. If the player chooses to leave, Mickey says goodbye to the ghost and begins to go home, but the ghost decides to go with him (however, if the player has only collected at least eight mirror pieces, the ghost wont be able to go with him at all). After Mickey wakes up, he goes downstairs to get something to eat. A model of the ghost is shown hanging on the ceiling fan and the ghosts laughter is heard.\r

Gameplay\r
The game uses a simple point-and-click mechanic which involves using a cursor to guide Mickey Mouse to various locations. Mickey will react to what the player does and what he encounters in the game by expressing curiosity, getting mad, falling down, running away, standing his ground, or other actions. At certain points, the player is able to have Mickey perform a special move that generally involves having him stomp on an onscreen enemy.\r
\r
Mini-games, such as having Mickey fly an airplane or ski down a mountain, are available throughout the game. Special souvenirs may be uncovered as well, which are displayed in Mickeys room at the end of the game, such as Plutos collar or Minnies bow.\r

Development\r
At Nintendos Space World 2001 show, where it was just beginning to show more Nintendo Gamecube titles, a Disney title was announced which showed some screenshots of this game, which was assumed to be a platformer like much the vein of Disneys Magical Quest on the Super NES. But when Nintendo finally announced the product at the 2002 Electronic Entertainment Expo, this was proved that it was a completely different game instead.\r

This games plot was based on Thru the Mirror, a 1936 Mickey Mouse cartoon. The opening sequence also plays out similar to the beginning of the cartoon, even perfectly replicating Mickeys walk through the mirror animation. One part later in the game, where Mickey grows to a tremendous size then shrinks to a minuscule size, was also replicated exactly as in the cartoon.
