Measle Stubbs is not a boy known for his good luck. He's thin and weedy and hasn't had a bath for years and has to live with his horrible old guardian Tramplebone. Just when Measle thinks things can't get any worse, he's zapped into the world of Basil's toy train set. There's something lurking in the rafters and a giant cockroach is on his trail. It's times like these you need a few friends ... and a plan.
