Only you can return the demons to the chest...because you let them out!In the initial episode, the gang are thrown off course on a trip to Honolulu in Daphne's plane, landing instead in the Himalayas.

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.

Tom Ruegger was associate producer and story editor, and the irreverent, fourth wall-breaking humor found in each episode resurfaced in his later works, among them A Pup Named Scooby-Doo, Tiny Toon Adventures, and Animaniacs.

He would only wear this outfit four more times in the more than three decades since it was introduced, the last appearance being in 2001s Scooby-Doo and the Cyber Chase as part of the gang's digital counterparts.

Hints that this style may be coming back were implied in 2019's Scooby-Doo Return to Zombie Island, where Shaggy is seen wearing a red floral shirt while laying out on a boat.

Lured to the enigmatic Befuddle Manor, the gang must contend with a ghoulish convention of ghosts and the mysterious Shadow Demon led by vampire witch Queen Morbidia.

The gang is trapped in the classic horror film "The Son of the Bride of the Ghost of Frankenstein" by Zomba, a zombie-like ghoul who attempts to nab the Chest of Demons from Scooby's heavily guarded room.

After an audition for another anthropomorphic dog, Flim Flam has Scooby replaced by a lazy and dim sheepdog named Bernie Gumsher.

This not only causes child protests across the nation which in turn leads to a televised address from President Ronald Reagan, but also causes the gang to be captured by Time Slime.

Vincent Van Ghoul takes Scooby to the future to show him what the world will be like if he does not return to stop Time Slime from releasing the demons that were previously reimprisoned.

(short for Spook and Poltergeist Society), the vampire demon Rankor tricks Vincent Van Ghoul into looking into the Eye of Eternity, which slowly turns him into stone.

The series was heavily profiled in the Christian fundamentalist documentary Deception of a Generation as an example of alleged occult influences on children's entertainment.
