In this danger-and-intrigue-packed comedy, Shaggy and Scooby-Doo move into the ultra-luxurious mansion of Shaggy's Uncle Albert, who has mysteriously disappeared. On their first night in the mansion, they discover Uncle Albert's secret lab, filled with gadgets including a transforming Mystery Machine and new Scooby Snacks infused with a top-secret technology that gives Scooby-Doo superpowers!
