Toestomper is mean, rude, and disgusting. Along with his friends Nightmare, Basher, and Barfy-the Rowdy Ruffians-he loves to make trouble and pick on folks. But when a slew of warm and fuzzy caterpillars begin following Toestomper around and look up at him with their pleading eyes, he's not sure what to do. He yells at them to leave but they still won't go, and then they start to look a bit cold huddling outside Toestomper's hut. Gradually the fuzzy furballs wend their way into Toestomper's life. But what will the Rowdy Ruffians think of Toestomper's change of heart?
