But it soon turns out to be much more than a night full of tricks and treats when Scooby, Shaggy, Scrappy, and the kids must travel to the world of Halloween spirits in order to stop a dark force that could destroy the entire world after the magic of a real live fairy princess is stolen. And that's not all, as Scooby and the gang will have to come face to face with the all powerful ruler of Halloween... the Goblin King! NOTES: Only ocs are mine. Happy Halloween!
