The Final Conflict

THE (REAR) END IS NEAR!!!!

ZACK FREEMAN (and his butt) have twice saved the world from total reek-dom, and he's pooped. But now the young butt-fighter faces his nastiest challenge yet. Hundreds of thousands of Great White Butts are attacking the earth. Humanity is about to be giant-brown-blobbified . . . to extinction!

Zack has no choice but to join forces with Robobutt and travel 65 million years back in time, to the reign of the prehistoric buttosaurs. Can Zack and his butt battle the Tyrannosore-arses, juggle a giant arseteroid, and come from behind to beat back the butts? They'd better -- before the earth gets wiped!
