Inspired by a TV commercial, the mayor decides to resurrect the Jefferton theme park Pioneer Island, which burned to the ground many years ago under mysterious circumstances.
Although he has limited experience with dogs, Tom is selected by the mayor to provide a canine matchmaker for Jefferton's yearly holiday Toodle Day, in which all eligible dogs in town are married.
When Tom comes up with a novelty T-shirt depicting a top hat-doffing rat and a catchy phrase, the mayor is so delighted by it that he grants Tom a kiosk in the mall to peddle his wares in time for the Christmas shopping season.
After all three of his stepsons have heart attacks and Joy verbally accosts him for interrupting her breakfast, Tom decides to form a health camp for boys.
