Shaggy, Scooby-Doo and Scrappy-Doo go down South to collect Shaggy's inheritance from his Uncle Beauregard, but as they travel to Beauregard's run-down mansion, they soon encounter all sorts of spooks, scary skeletons and more. Hiring the bumbling, ghost-busting Boo Brothers -- who are spirits themselves -- the trio tries to exterminate the menacing apparitions in this feature-length animated special. Casey Kasem provides Shaggy's voice.
