Suddenly with enough medals to enter Chrome Dome Castle, team Bo-bobo rush ahead to finish the empire. But unexpectedly, three more of the Shadow Big Four pop up, with Bo-bobo forced to take on three super-powerful bags who can destroy the world, Don Patch letting the other two go in to destroy the rest of the competition, and Lee Fishcake...dressing up as Rem. But just when Bo-bobo seems too weak to take on the force of the Shadow Chrome Dome, his "super" power (and some gun-toting bears in a nosehair) force them to prepare for their final stand!
