The 13 Ghosts of Scooby-Doo

The 13 Ghosts of Scooby-Doo is an American animated supernatural/mystery-comedy television series produced by Hanna-Barbera (H-B) for ABC's Saturday morning children's programming. It ran in the fall of 1985, airing 13 episodes that spanned one season. It was the seventh Scooby-Doo series after Scooby-Doo, Where Are You!

After accidentally releasing the thirteen most terrifying ghouls on the face of the earth, Scooby-Doo and his friends are forced to pursue them, guided by a warlock named Vincent Van Ghoul, and return them to their prison inside the Chest of Demons.

The entire series has been released on DVD.

Aftermath
The series was canceled due to budgetary restraints (and apparently not because of bad ratings), leaving one or two of the ghosts free (depending on your own view). Why they couldn't have caught each of those thirteen ghosts in each of those thirteen episodes, is beyond my comprehension.

More than 30 years later, Warner Bros. Animation hired Tim Sheridan to write an ending to the series in the form of the direct-to-video film, Scooby-Doo! and the Curse of the 13th Ghost, which was released on February 5, 2019. As this was number 29 in a series of DVD movies that were more on the traditional side of things, i.e. ghosts are just bad guys in masks, this movie had to abide by that rule by retconning The 13 Ghosts of Scooby-Doo into possibly being a hoax. If believed to be real and not just the result of a hallucination brought on by spending an extended amount of time in the Himalayas, the thirteenth ghost was Vincent Van Ghoul's ancestor who had become corrupted by his own growing power and attempted to repent for his sins by following Vincent around like a guardian angel.

Music
The music was composed and conducted by Hoyt Curtin, with supervision from Paul DeKorte.
