Hanna-Barbera sure knows how to craft some classic Scooby-Doo toons. In the latest adventure, Scooby-Doo! Mystery Incorporated: The Secret Serum, Cartoon Network showcases the group up against a new demonic foe: a vampire loose in the town! After reports flood in of the blood sucker terrorizing the residents and stealing an odd assortment of loot, the gang arrives to do some sniffing around, only to find that the suspect has a connection to them — it’s Daphne’s mom! How embarrassing. The news is devastating, rocking Mystery Inc. in two, with Daphne and Velma on one side, Fred, Shaggy, and Scooby on the other — but the mystery is still at the heart! The toon aired last Monday to rave success, prompting upcoming reruns on the CN. Take a look at a clip of the toon in motion.
