While cleaning out his rabbit hole, Bugs Bunny finds a map leading to a location marked "C Castle", although he does not know what the C stands for, as the letters after the initial "C" have worn away.

Bugs first navigates various outer environments of the Taz Island: a forest, caves, a hollow tree, mountains, a stream, and a tropical area.

To advance through each level, he must collect eight keys while avoiding or fighting back against a large cast of Looney Tunes characters.

[2] Besides Taz, these include Beaky Buzzard, Count Bloodcount, Daffy Duck, Elmer Fudd, Elvis the gorilla, Foghorn Leghorn, Fox Pop, Gossamer, Little Ghost, Marc Antony, O'Pat the leprechaun, Pepe Le Pew, Wile E. Coyote, Witch Hazel, and Yosemite Sam.

Taz himself can not only roam around the map but also spit multiple projectiles and quickly catch up to Bugs when he is far away by spinning through the air in a vortex.
