Tom loves nothing more than fooling around. He drops things from bridges, plays with barrels in alleys, and generally causes a wonderfully joyful mess. But his fierce aunt, Miss Fidget Wonkham-Strong, takes absolutely no nonsense from anyone. Tired of Tom's constant playing, she calls upon the terrifying Captain Najork and his team of hired sportsmen to teach the boy a strict lesson. Captain Najork is seven feet tall with a voice like thunder, and he challenges Tom to intense games of womble, muck, and sneedball. It seems impossible for a young boy to defeat a crew of professional sportsmen. However, the Captain is about to find out that a boy who is an expert at fooling around might just have the perfect strategy to win it all.
