Scooby-Doo (Don Messick) goes after real, live ghosts -- 13 of them, to be exact -- in this short-lived continuation of the Saturday-morning saga that brings Shaggy (Casey Kasem), Scrappy-Doo (Messick) and Daphne (Heather North) along for the ride but leaves Fred and Velma behind. The gang also consists of a warlock named Vincent Van Ghoul (Vincent Price) and an impish trickster named Flim Flam (Susan Blu).
