On the island kingdom of Akrillic, the ruler Plok discovers his prized flag has vanished, prompting a voyage to nearby Cotton Island where he confronts the mischievous Bobbins Brothers and reclaims his prize. Upon his return home, he finds his island overrun by a plague of hopping blue fleas—a scheme orchestrated to leave his domain defenseless while he chased his missing banner. Plok learns through a vision of his grandfather's past that a magical amulet holds the key to combating the infestation, granting him the power to transform into a saw as he works to purge Akrillic of its invaders and face increasingly powerful foes determined to seize control. His quest takes him through treacherous terrain and encounters with creatures like the magician Penkinos, the giant spider Womack, and the rocky colossus Rockyfella, leading ultimately to the Fleapit—a subterranean stronghold where the Flea Queen rules her swarm. With an arsenal of vehicles and weapons at his disposal, Plok must defeat the matriarch responsible for the infestation and restore peace to his kingdom.
