"Who's Who In Scooby-Doo?"
Mystery Inc is called into Kasem County to investigate a rash of strange monster sightings. When the gang arrives, they learn that the monsters are all villains from their past mysteries. They follow a map of sightings and stumble into an old museum where the attendent seems to be very suspicious as he packs up the items in the museum for transport to a newer location. The gang heads down to the new museum where they run into more familiar villains as they capture the villains and unmask them as the museum curorator and the attendent. They bought most of the costumes and props from the Mystery Inc villains in order to throw the gang off the real trail.
