Riku: This is no ordinary mirror. It is a gateway to another world. A gateway that opens once every thirty moons.
Riku: It has always been kept in the throne room of Disney Castle. But when Ortensia took over the Crystal Empire, we sent it here for her to watch over.
Sora: [sigh] I had always hoped that Mortimor would someday use it to return, to come back to Toontown seeking my guidance. Obviously, this is not what has happened.
Ortensia: Mickey, you must use the mirror to go into this other world and retrieve your crown. Without it, the other Elements of Harmony have no power and Toontown is left without one of its most important means of defense.
Riku: Your crown does not belong in the place Mortimor now calls home. And in his possession, your Element of Harmony will no doubt be used to bring harm to the inhabitants of this other realm. They will not have the power to defend themselves.
Sora: You understand the importance of your task?
Mickey Mouse: Of course.
Sora: Good. Then you must go at once.
Mickey Mouse: [sigh]
Donald Duck: Whoa, whoa, whoa! He's going, we're going with him!
Donald Duck: Right, guys?
Goofy: Oooh! I'm so 'nervicited'!
Minnie Mouse: You do realize that's not a real word, right?
Sora: I'm afraid I can't let you go.
Donald Duck: What?! Why not?!
Sora: Sending all of you could upset the balance of this alternate world, creating havoc that would make it impossible for Mickey to get the crown back from Mortimor. This is something Sorcerer Mickey must do alone.
Riku: Time is of the essence. On the third day, when the moon reaches its peak in the night sky, the gateway will close. And once it does, it will be another thirty moons before you will be able to use it to return.
Rest of main cast: [remarks of encouragement] Pluto, NO!
