The Bugs Bunny Crazy Castle is a 1989 action puzzle video game developed by Kemco for the Family Computer Disk System and Nintendo Entertainment System. It was also released for the Game Boy in Japan as Mickey Mouse and in North America and Europe as the same name as the North American NES release

The object of the game is to guide the character through a series of rooms collecting hearts/carrots. While presented in a side-scroller format, Crazy Castle differed from standard side-scrollers such as Super Mario Bros. in that the character did not have a jump function; therefore, only by taking different routes could the character avoid enemies. Some of the levels had boxing gloves, invincibility potions, safes, crates, flower pots, or ten-pound weights that could be used against the enemies in the game. As a result, the game had a "puzzle-solving" atmosphere.

Players score 100 points for every heart/carrot with the last one in each floor giving the player an extra life, 100 points for every enemy defeated using invincibility bottles, 500 points per enemy using boxing glove and 1000 points per enemy that gets hit with heavy objects.

Honey Bunny has been kidnapped by Wile E. Coyote, Yosemite Sam, Daffy Duck, and Sylvester, and Bugs must travel through 60 levels in order to save her. To get past each level, Bugs must collect all 8 carrots in each level.

An evil witch has kidnapped Honey Bunny. Since she is Bugs Bunny's girlfriend, he must travel to the witch's castle and rescue her. Bugs will have to work his way through 28 levels, where he'll have to collect eight keys to open the door to the next level. However, there are a number of enemies standing in the way including Yosemite Sam, Daffy Duck, Wile E. Coyote, Sylvester, Foghorn Leghorn, Tasmanian Devil, Beaky Buzzard, Spike, Merlin the Magic Mouse, and Tweety. Luckily, there are number of power-ups like potions, weapons, shields, and tools to help Bugs on his quest. A password keeps track of what levels you have completed, so you don't have to start from the beginning every time you play. See if you can rescue Honey Bunny again in BUGS BUNNY CRAZY CASTLE 2.

Find your way to the mysterious Crazy Castle. You will pass through a wide variety of locations in which you will encounter familiar Looney Tunes characters such as Taz, Yosemite Sam, Wile E. Coyote, Daffy Duck and Elmer Fudd.

The gameplay is pretty much the same as the other Crazy Castle games in the series.
