A Pup Named Scooby-Doo
She worked with the beach patrol, and was very suspicious of anyone at the beach, and her behavior only made the gang very suspicious of her. She was, also, a suspect at being the Headless Skateboarder, whereas tire tracks from her jeep were at all the places where the monster showed up.
All that time, she worked with Al, helping him in his drug smuggling operation. They also tried to make it look like Red Herring was the monster as one of his pranks. She and Al were then arrested by Gnarly Charlie, who was an undercover FBI agent all that time investigating the drug smuggling operation.
