 An updated version of the classic Hannah-Barbera mystery cartoon. The story for this series is about the same as for the older series, with one major change: the Mystery Machine gang is now joined by Scooby s nephew, Scrappy Doo. Unlike his uncle, Scrappy is constantly looking for a fight, and it is all Scooby and Shaggy can do to keep him from hurtling head-on into every ghost and monster they encounter. Of course, after doing a little investigating, most of these ghosts and monsters turn out to be not so scary after all.
