ScoobyDoo and ScrappyDoo (19791983) An updated version of the classic Hanna-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. Joining the gang is Scooby's pint-sized nephew, Scrappy-Doo. Unlike his uncle, the little pup 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, the hauntings always have a more down-to-earth explanation.
