The Bugs Bunny Crazy Castle

The Bugs Bunny Crazy Castle, known in Japan as Roger Rabbit (ロジャーラビット) for the Famicom Disk System, is a 1989 action-puzzle game developed by Kemco for the NES. It is the first game in Kemco's It is the first game in Kemco's Crazy Castle series and the only one that was released for a home console; the four subsequent games in the series were released on handheld devices.

The North American NES game was a modified version of the Japan-exclusive Family Computer Disk System title, Roger Rabbit. Roger Rabbit is the game's playable character, all the villains are all Who Framed Roger Rabbit-related, and hearts are collected. Due to Capcom owning the rights to develop and publish Disney film-based video games, as well as LJN already published Rare's own video game adaptation of the film, Kemco decided to use Bugs Bunny, due to him and Roger Rabbit both being rabbits, making it easier for Kemco to modify the Roger Rabbit game and release it outside Japan as The Bugs Bunny Crazy Castle.

A very similar game with different levels was released for the Game Boy in Japan as Mickey Mouse (ミッキーマウス)]], and in North America as the same name as the North American NES release. For the Game Boy version, Kemco's license to develop and/or publish video games based on Who Framed Roger Rabbit became outdated; however, they still had the license to create Disney-based video games, which they used to create Mickey Mouse for Game Boy. An early beta version of the game shows the working title as Bugs Bunny Fun House.
