SCOOBY-DOO is an 'Ameri-canine' icon, the most beloved cartoon pooch of the past three generations. The snack-sniffing sleuth and his pals are in the midst of a huge popularity boom. Scooby and the gang are ready for a fun afternoon in the new Viking Village at Happy Sally Land, a nearby amusement park. Scooby and Shaggy can't wait to ride the Nordic Nor'easter, the rip-roaringest roller coaster around. But when an angry Viking sabotages the ride and scares away all the visitors, it looks like no one will ever get ride the new roller coaster. It's up to the gang from Mystery, Inc. to track down the Viking before his villainy closes down Happy Sally Land -- forever.
