The Omaha World's Fair give the gang an electrifying education in computer mad science inside the High Tech House of the Future. Daphne can't wait to see her favourite band, The Hex Girls, shoot their latest video in Transylvania.

But just when the group strikes their first chord, The Vampire Strikes Back! In Homeward Hound, a fiercely fanged cat creature petrifies the competing pooches at a dog show, including the visiting Scooby Doo!

Then it's off to the city by the Bay for the Grind Games in San Franpsycho, where a seaweed sprouting ghoul from Alcatraz prison scares competing skateboarders to the core. When the band Simple Plan meets an invisible hijacker en route to the Montreal Rock Festival, only Scooby and the gang can see the light in Simple Plan and the Invisible Madman.
