Everybody loves amusement parks - unless they're haunted! In Scooby's Fun Zone, Scooby-Doo, Shaggy and Scrappy-Doo pit their wits against a muscle-bound strongman. Then, the crew attends a carnival at their Central High alma mater and lose their science teacher, Mr McDrabble, in The Crazy Carnival Caper. Talk about kids with class! Finally, the gang visits a state fair and dreams of returning to the present when they lose Daphne in an automated house of the future in High-Tech House of Horrors. Where there's a mystery that needs solving, Scooby-Doo comes through!
