The series was created and produced by Mitch Schauer. Tom Ruegger was associate producer and story editor, 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". Of "The 13 Ghosts of Scooby-Doo", Ruegger recalls not being fond of the Flim-Flam character or the other added characters in the cast. As with most of the other early-1980s "Scooby-Doo" entries, original characters Fred Jones and Velma Dinkley do not appear, and the enemies were real (within the context of the series) ghosts and not simply humans in costume. "13 Ghosts" ended its run after 13 episodes and was replaced by reruns of "Laff-a-Lympics" in March 1986, before the end of the season.
