Synopsis
It finally happened! Somehow, after multiple failed attempts, Pinky and the Brain have successfully conquered the planet! All hope is now lost--or is it? After being warned by his descendant Ace of what the future holds, Bugs Bunny decides to assemble a group to help avoid disaster. Which fearless soldiers will he send into battle? He won't. He's sending a unlikely team of out-of-control whackjobs. Babs and Buster Bunny, Plucky Duck, Freakazoid, Skippy and Slappy Squirrel, and the Warner Siblings are recruited to help defend their world. This may very well be the end of our own sanity!
