In late 2025, Kings Island officially retired Boo Blasters on Boo Hill, a long-standing interactive dark ride in the Planet Snoopy area. The ride originally opened in 1992 as Scooby-Doo and the Haunted Castle before being re-themed in 2010. This closure made way for the park's major 2026 attraction, Phantom Theater: Opening Nightmare, which serves as a spiritual successor and nostalgic "reimagining" of the fan-favorite Phantom Theater that occupied the space in the 1990s. The new ride features updated animatronics and modern special effects while paying homage to the original characters. This move is part of a broader 2026 trend at Six Flags/Cedar Fair parks to revitalize classic IP and dark rides to appeal to both new families and long-time fans of the park’s history.
