When a violent dog begins terrorizing Crystal Cove, Stone wrongfully arrests and locks up Scooby-Doo. Velma finds a robotic leg at the scene of the crime, and accuses Jason Wyatt from her robotics class who is obsessed with her. The gang then goes to visit Scooby in Crystal Cove’s Animal Asylum, where they encounter the criminal genius Professor Pericles. He warns Fred to beware those closest to him. The hound attacks, and the gang breaks Scooby out. They trap the dog and its owner, revealing the owner to be Jason’s mother, who wants revenge on the gang for not befriending Jason. Shaggy chooses Scooby over Velma, reflecting on how much he missed his dog. Velma is unimpressed, and receives a text from Mr. E telling them to “follow the parrot”. A news article reveals Pericles has escaped the Asylum.
