The Addams family in this episode are all drawn in the style of the original Charles Addams "Addams Family" cartoon strip rather than as caricatures of the actors who played in The Addams Family (1964). This served as a backdoor pilot for The Addams Family (1973) animated series.
This is the only episode of TNSDMovies to be excluded from home video releases due to legal issues with the Charles Addams estate. It's also missing on Tubi.
