Clue Club Similar in format to Hanna-Barbera's successful Scooby-Doo, the show centers around four adolescent friends who open the title's private investigation agency out of Larry's suburban residence. They are Larry (19), Pepper (18), D.D. (16) and Dottie (13). They solve mysteries with the help of their two talking hounds, Woofer and Wimper. The dogs only talked to each other and the camera, they were not understood by the human characters. Clue Club mysteries usually involved investigating bizarre crimes such as a movie director vanishing or a two-ton statue disappearing into thin air. Their relationship to the police was closer than most of Hanna-Barbera's variations of the formula, with the local Sheriff often requesting their assistance on cases as well as making arrests at their conclusion.
