For this season, many of the writing credits are missing. In the book 'The Flintstones: A Modern Stoneage Phenomenon' by T.R. Adams, it simply says "Not Available" for most of the writing credits.
The characters of Len Frankenstone and his mentor are parodies of Ben Casey (Vince Edwards) and Doctor Zorba (Sam Jaffee) from the Ben Casey TV show.
