Toxic Bunny

Toxic Bunny is a side-scrolling action platform game for DOS computers released in 1996 by Celestial Games. The game's premise is that a bunny named Toxic, a coffee-guzzling, gun-slinging maniac, is having a really bad day. The game covers four large levels: Toxic hunts the person responsible for interrupting his coffee break, brainwashing all his friends, and covering the planet with a decaffeinated goo. Within the game, you can use any number of incredibly large weapons, including a Nitric Hamster Launcher, while squashing aliens with rusty nautical equipment.
The game has been called a psychedelic parody of the Epic Games character, Jazz Jackrabbit. A sequel has been announced for Xbox and PlayStation 2 in 2000, but was cancelled.
