1st series not to feature Scooby Snacks.
Mel Blanc was the first choice for the voice of Scrappy-Doo, but his salary demands proved excessive. Frank Welker and Don Messick also auditioned for the role, with Messick eventually taking over from Lennie Weinrib from 1980 onward.
Voice Actress Marla Frumkin filled in for Patricia Stevens for the voice of Velma Dinkley when Stevens could not continue for health reasons. Frumkin played Velma from The Ghoul, the Bat, and the Ugly (1979) to The Ransom of Scooby Chief (1980). Marla Frumkin only has one line in "The Ransom of Scooby Chief" - "Have a good visit."
Scrappy-Doo, a small feisty dog, was what the writers originally considered making Scooby-Doo before going with the large cowardly dog.
Was one of the few contemporary Hanna-Barbera shows released on VHS by Worldvision (and via Guild Home Video in the UK) in the early days of video. Most of the early catalogs were of retrospective shows like Top Cat (1961), The Banana Splits Adventure Hour (1968), The Atom Ant Show (1965) and The Secret Squirrel Show (1965). Scooby Doo, Where Are You! (1969), which would have been more in keeping with the era of shows Worldvision released, would not see any substantial home media release for many years.
