Stewart Penders is a 12-year-old kid who loves comics. He loves drawing his own creations, especially the adventures of his fantasy alter ego, Stupendous Man! Part of his passion for comics comes from his late granddad, who was a great comic book artist. Grandad has just died, leaving his house and its contents to Stew's family. But when his family move in, they are greeted by a pig in a top hat running amok through the house. When Stew explores the house later, he finds a discarded comic strip in the attic - featuring an image of the very same pig they just saw - and beside it a mysterious pot of ink. When Stew starts drawing with it, his artwork springs into life - and so begins a hilarious adventure that could only have come from the madcap mind of Mr Steve Cole, bestselling author of Astrosaurs, Cows in Action and Slime Squad!
