In the initial episode, the gang are thrown off course on a trip to
Honolulu in
Daphne's plane but accidentally landing instead in the
Himalayas. While inside a temple,
Scooby and
Shaggy are tricked by two bumbling ghosts named Weerd and Bogel into opening the Chest of Demons, a magical artifact that houses the 13 most terrifying and powerful ghosts and
demons ever to walk the face of the Earth. As the ghosts can only be returned to the chest by those who originally set them free, Scooby and Shaggy, accompanied by Daphne,
Scrappy-Doo, and a young boy named
Flim Flam, embark on a worldwide quest to recapture them before they wreak irreversible havoc upon the world. Assisting them is Flim Flam's friend, a
warlock named
Vincent Van Ghoul (based upon and voiced by
Vincent Price), who contacts the gang using his
crystal ball and often employs magic and witchcraft to assist them. The 13 escaped ghosts, meanwhile, each attempt to do away with the gang lest they are returned to the chest, often employing Weerd and Bogel as lackeys.
Fred Jones and
Velma Dinkley were both absent in this incarnation. In
Scooby-Doo! and the Curse of the 13th Ghost, it is revealed that they were away at summer camp, although in
Scooby Doo! Mystery Incorporated, Fred may have gone to a camp that specialized in traps as he referred to it as "Trapping Camp". ==Voice cast==
