The Earth is under attack by a horde of Alien Brain uh Thingys! Humans, succumbing to ray-guns, mind-control, and shiny flying saucers, have failed to defend their planet and let it fall easily into the clutches of the Big Brain and his army of Brain Thingys. The only hope left for mankind is three Teenage Zombies that have arisen from a graveyard disturbed in the invasion. The undead trio ignores their normal human victims in favour of the pulsing pink brains they see EVERYWHERE – all the while being lured to the ultimate lunch: THE BIG BRAIN! The Big Brain soon realizes hes overlooked this Super Race as they inexplicably resist mind control, are unaffected by ray-gun wounds, and devour his Brain Thingy Armies like sweets! He refocuses his efforts and resources to battle the Earths greatest champions: The Teenage Zombies!
