Aired before Nickelodeon picked up the series, on Halloween of 1990 to fit the theme of the plot; its chronological airdate as the fourth episode was September 5, 1992.
One of two episodes to open in a storytelling rather than at the fire, and the only one where the story was never finished and didn't have anything to do with the main story (Eric was telling a cliffhanger before David told "The Tale of the Twisted Claw" for the night's full story).
This was the pilot episode that aired on Halloween night in 1990. After the show was picked up, the Midnight Society was recast and their scenes were reshot, with the exception of Ross Hull (Gary), who played Frank in the original pilot.
Ann Page, who plays Miss Clove, is married to Aron Tager, who plays Dr. Vink (and Zeebo) throughout the show.
At the beginning of the episode it is suggested that David tell a story because it's been awhile since he has, yet in full series air date order David told the story in the previous episode. This is because this episode initially aired as a stand alone Halloween special before Nickelodeon officially ordered it to series.
