Karen Thurston's "G crown logo" shirt was also worn by Margaret Brewer in Stay Out of the Basement: Part 2 (1996) in Season 1. It was never revealed where the logo is from, but it was likely from a now shut-down Canadian company, or it was designed specifically for the characters in the show. The logo itself is an oval formed by two black curved arrows, filled in with gold and a graphic of a capital letter G with a plus symbol underneath it and a three-pointed crown above that.
This episode is based on Goosebumps book #01.
While the main TV show theme was released, the soundtrack that plays throughout Welcome to Dead House (mostly piano music and creepy noises) was never released at all. The company has yet to inform whether or not that soundtrack still exists or if it will ever be released.
When Mr. Dawes holds up the Dark Falls Daily Newspaper with the headline "Accident At Chemical Factory Kills Workers" the sub-headline text, though near-illegible, reads: "What is the damage to our lovely town? Should we evacuate? How toxic is it?" and the author is listed as "John Lamont, town reporter". On high-definition versions of the show the text is easier to read; however, the smaller text that tells the story is still unreadable except on the original film recording of the show. There is no known copy of the prop newspaper in existence.
