Daves disgusting. He has a dog that farts & hes way too interested in snot & sick for his Aunt Doras liking. But really he only wants to find out about fascinating things like the human body & creepy crawlies &.. .flesh-eating maggots. When some real-live maggots arrive for Dave in the post he discovers that science can turn dangerous! Can he keep the squirmy wormlets under control before they chomp their way through the whole neighbourhood?
