The 13 Ghosts of Scooby-Doo

In The 13 Ghosts of Scooby-Doo, mystery and mayhem prevail when Scooby-Doo and Shaggy accidentally set free a pack of troublemaking spooks. On a trip to Honolulu, Daphne's plane winds up landing in Tibet. While visiting a temple, Scooby and Shaggy are tricked into opening the Chest of Demons, which houses 13 of the most-frightening ghosts and ghouls to ever haunt the earth. The ghosts however, can only be returned to the chest by those who originally released them. To prevent them from wreaking havoc upon the world, the gang embarks on a global quest to recapture them. Scooby-Doo's nephew, Scrappy-Doo, a mischievous boy named Flim-Flam, and warlock Vincent Van Ghoul join the team throughout the season, as they set out to trap the escaped specters.
