Having successfully repaired their vessel and escaped Earth, the cosmic funk ambassadors ToeJam and Earl return home to Funkotron only to discover that human stowaways have infiltrated their ship and now threaten their entire world. The arrival of these terrestrial intruders sends shockwaves through Funkotron's society, causing widespread chaos and even frightening Lamont the Funkapotomus—the very embodiment of funk itself—into another dimension entirely. Tasked with undoing the catastrophe they've inadvertently triggered, the pair must round up every last Earthling and restore peace to their planet before funk vanishes forever.
