Ruh-Roh! Everybody's favorite quivering sleuths-Shaggy and his lovable Great Dane, Scooby-Doo-are back! In this all-new, 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, which at the click of a remote, can morph into any number of transportation modes, and new Scooby Snacks infused with a top-secret technology that allows our canine hero to fly, become a towering robot or even turn himself into a giant magnet. Shaggy and Scooby-Doo are on a mission to find Uncle Albert and keep the Scooby Snack technology out of the hands of the outrageously evil villain, Dr. Phineus Phibes. Along the way, they will run into the occasional mystery that needs solving, and sometimes they even get a little help from Fred, Velma and Daphne.
