An updated, hour-long version of the classic Hannah-Barbera mystery cartoon. Fred, Daphne, Velma, Shaggy and Scooby-Doo travel from town to town in their van, The Mystery Machine, solving cases of hauntings, monsters and unexplained occurrences. In this series, the gang is joined by Scooby's pint-sized nephew, Scrappy-Doo. Unlike his uncle, little 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 not to be so scary after all.
