Boomerang is a sister channel to Cartoon Network that often does reruns of older shows, the most famous being Scooby Doo.

Later that same year, "Scooby-Doo! and the Reluctant Werewolf" hit television screens, bringing the three cartoon icons back for a monster race after Shaggy is suddenly transformed into a werewolf.
