But this time they're not fighting each other–this time they've joined forces to save the Earth from the most serious threat it has ever an invasion of zombie bums ... zombie bums from Uranus. Join Zack, his bum, Eleanor, Silas Sterne, the Kicker, the Smacker, the Pincher, the Forker, the Flicker and the Mutant Maggot Lord in the heart-stopping, nostril-blasting, Zombie-Bums-from-Uranus-filled sequel to The Day My Bum went Psycho.
