The Bugs Bunny Crazy Castle (Game Boy)

's Mickey Mouse was originally developed and published in Japan, and later localized in Western countries as The Bugs Bunny Crazy Castle. It is an action-puzzle game for the original Game Boy. Before the worldwide release of Bugs Bunny in Crazy Castle 4, this game was re-released in Japan as Bugs Bunny Collection.

Gameplay
The game includes a total of 80 stages: 41 stages from Kemco's Roger Rabbit (FDS) (localized as The Bugs Bunny Crazy Castle for NES), plus 39 new stages.

In each stage, Mickey Mouse (or Bugs Bunny) should dodge the enemies and collect 8 hearts (or carrots). The puzzle side of the game consists in dodging the enemies and use the sparse items to defeat just some of them.

The enemies in the original versions are Zeke Wolf, Peg-Leg Pete, March Hare and Vulture. In the localized version, they were replaced by Sylvester, Yosemite Sam, Daffy Duck and Wile E. Coyote. Zeke Wolf (Sylvester) can climb stairs and crawl into pipes, whereas the other three just walk back and forth on platforms.
