In 1999 USAopoly, under license from Hasbro and Hanna-Barbera Productions, produced a Clue board game themed on the Scooby-Doo! cartoon series. The game was originally made for exclusive sale at the Warner Bros. Studio store. The cartoon team of mystery-solving sleuths seem a perfect fit as they assume the standard roles of the well-known characters in the original Clue game. Scooby-Doo himself plays the part of Colonel Mustard.
