Boo Blasters on Boo Hill is an interactive family dark ride designed and manufactured by Sally Corporation. The ride opened in 2010 at four Cedar Fair amusement parks — Canada's Wonderland, Carowinds, Kings Dominion, and Kings Island. The ride was a slight alteration and replacement of Scooby-Doo! and the Haunted Castle after Cedar Fair chose to remove all Hanna-Barbera branding from each of their parks by 2010.
