The gang goes on a trip to check on Velma's younger sister, Madelyn. She's been studying stage magic at the Whirlen Merlin Magic Academy, where apparently there have been sightings of a giant griffin. The gang decides to investigate. Everybody's favorite canine detective is back again. The Scooby Gang still seem fresh and vibrant in their latest straight-to-DVD adventure, Scooby-Doo: Abracadabra-Doo, over 40 years after their first television appearance. The Mystery Machine is a newer model and now has a very annoying GPS, but that's about all that's changed.
