A cowardly canine and his teenage friends romp through otherworldly animated adventures in this Hanna-Barbera production, which was ABC's less spirited answer to CBS's successful `Scooby-Doo' cartoon series. Four animated incarnations of `The Partridge Family' kids---Laurie, Danny, Chris and Tracy---were featured in the show and their voices were provided by the actors who played them in the sitcom.
