Synopsis by Jason Buchanan
A wicked warlock has cast a diabolical spell over Mystery, Inc. gang, and now it's up to Shaggy and Scooby-Doo to save the day. Join the lovable Great Dane and his easy frightened friend as they attempt to track down the Amazing Krudsky (voice of Wayne Knight), a second rate carnival magician who's using magic stolen from Princess Fairy Willow (voice of Hayden Panettiere) to transform everyone into grotesque Halloween monsters. If the dynamic duo can just hop on the Grim Reaper Railroad and make their way to Halloween land before Krudsky, perhaps they can retrieve the Goblin scepter from the Goblin King (voice of Tim Curry) and save the day. It's not an easy assignment, but fortunately Scooby and Shaggy have a little help from a friendly Jack O'Lantern and a flying broomstick that takes them on the ride of their lives. Additional voice talents include Jay Leno, Lauren Bacall, Wally Shawn, and Russi Taylor.
