Paperback / softback Edition 2017
Willy and Peter love beans, onion dip, and stinking up school buses. But a search for a birthday gift for little sis lands them in a big stink. Captured by mad clowns, the boys unmask a putrid plot to destroy the world with Weapons of Mass Flatulation. From flying camels to stormy seas, can they save humanity from ex-stink-tion?
