The Khat civilisation has long feuded with the residents of Planet Muss. Things have been a little quiet between the two warring factions of late, but all that is about to change. For one crazed and bitter Khat, the war is about to start up again! Dark Claw has been hiding away, biding his time, but now he will unleash his master plan. His weapon: Fworgonzola, the smelliest substance ever known!

With this deadly cheese he will lure the Muss to their deaths, every last one of them. But he hasn't counted on three brave young warrior Muss: Onlee One, Chin Chee and Hammee. Between them they are a force to be reckoned with, and their mission is to destroy the evil Dark Claw, once and for all . . .
