Music box (world)

The Music Box World is the setting of the game Wario Land 3. It is an entire world inside a tiny Music Box. The world is divided into four sections: North (the game starts here), South, East, and West. No one is sure who created this world.

During the events of Wario Land 3, Wario crashes his airplane into a large forest while out flying. He eventually finds the Music Box holding this world inside a nearby cave, continually trying to play it before giving up due to his lack of success. As Wario was complaining over the past events, he was engulfed in a flash of light and soon found himself inside the Music Box World, where he was greeted by a hidden figure who claimed to have once been the world's ruler. According to this figure, a dark spell was placed upon him that had sealed him within the room they conversed in. The power used to seal him away was contained in five small Music Boxes; as such, collecting these Music Boxes could allow the figure to escape his curse and free the Music Box World. Though Wario was initially uninterested in the figure's request to lift the spell over him, his mind was changed when he was told that he could keep any treasure he found on his way and would be brought back to his own world in the end. Wario eventually collected the Music Boxes and assisted the figure, but a terrible truth was revealed to him as he did so: The hidden figure was actually the evil Rudy the Clown, who had previously put a curse on all the Music Box World's native inhabitants, turning them into the monsters Wario had faced on his quest. Rudy and Wario eventually faced off in a fight, which Wario ultimately won. Afterward, Rudy the Clown's curse over the people of the Music Box World was lifted and Wario was not only allowed to exit the Music Box, but he was also given permission to keep all the spoils he had earned in his adventure.

Trivia

 * The Music Box World (or perhaps some sort of replica of it) made two brief cameos in the intro to Wario's stage in WarioWare: Twisted!, where it was shown on top of a piece of furniture in Wario's House.
