Scooby-Doo 2: Monsters Unleashed

Fred, Daphne, Velma, Shaggy and Scooby-Doo attend the opening of an exhibition at the Coolsonian Criminology Museum, which commemorates their past mysteries with displays of each culprit's monster costume. However, an individual known as the Evil Masked Figure interrupts the event, stealing two costumes using the reanimated Pterodactyl Ghost. Journalist Heather Jasper Howe ridicules the entire gang, starting a smear campaign against them. Concluding that an old vengeful enemy is the mastermind, the gang begins revisiting old cases. Dismissing the former Pterodactyl Ghost, Doctor Jonathan Jacobo, due to his apparent death during a failed prison escape three years ago, they suspect Jeremiah Wickles, the Black Knight Ghost and Jacobo's recently-released cellmate. Scooby and Shaggy, after overhearing the others criticizing their tendency to bungle every operation, and especially their most recent failure to secure the Pterodactyl Ghost at the museum, resolve to better themselves and act like real detectives.
