He recruits a ragged crew of school superheroes to help him, including Tortoise Boy, armed with Cedric the tortoise, the Human Hurricane, who possesses untold power in his bottom, and Really Annoying Girl. But with only a pack of cards, some toy ray-guns and a pair of old pants for help, can they do it? Find out in this nail-bitingly scary but hilarious story by a prize-winning author.
