the Mystery Gang have graduated high school and are looking to expand their business. They secure funding from the wealthy celebrity Simon Cowell, who suggests that the gang drop Shaggy and Scooby. Saddened, Shaggy and Scooby head to the bowling alley where they are attacked by small robots called Rottens, but are rescued by the Falcon Fury. Inside they are greeted by Dee Dee Skyes who introduces them to Dynomutt the Dog Wonder and Brian Crown - the son of the original Blue Falcon, who has retired. They reveal that the Rottens belong to famed criminal Dick Dastardly, who wants to capture Scooby for his own purposes that involve collecting the three skeletal heads of Cerberus. The group discover that a skull is in the Gobi Desert. However, upon arriving they discover that it is a trap set up by Dastardly who has already gotten the skull and only needs one more.
