Cartoon segments

The show also included the cartoon shorts:

• M*U*S*H (short for Mangy Unwanted Shabby Heroes): Sled dogs Colonel Flake, Major Hank Sideburns, Coldlips, General Upheaval (all voiced by Kenneth Mars), Bullseye, Trooper Joe, Hilda, and Sonar (all voiced by Robert Ridgely) work at a medical outpost in the frozen wasteland of Upper Saboonia. This cartoon is a lampoon of M*A*S*H. In his 2012 autobiography, Lou Scheimer stated that he had written the segment to be intentionally unfunny, a concept that Scheimer found to be a better concept than ABC did.^[7][4] While 30 episodes of the show were written, 23 of the said episodes were fully produced, and 14 of them have not surfaced.^[1]
• Fraidy Cat: Fraidy Cat (voiced by Alan Oppenheimer^[8]) has lost his eight lives and only has one life left which he is wanting to make it last. He is cursed with the ability to involuntarily summon the ghosts of his eight past lives, personified as their respective time periods (voiced by Allan Melvin, Lennie Weinrib and Alan Oppenheimer) as well as trying to say "nine" which summons Cloud 9 (voiced by Alan Oppenheimer) who tries to claim Fraidy's life.^[9]
• Wacky and Packy: A prehistoric caveman named Wacky and his pet woolly mammoth Packy (both voiced by Allan Melvin) get washed into a cave during an earthquake and they end up getting transported two million years into modern times as they work to survive in this time period.^[7][10]

Of all of the aired cartoon segments, only Fraidy Cat had the longest continued existence, with the last official home media release being distributed by BCI on a DVD set in 2006, 31 years after the show's conclusion.^[11]

The voice cast part of the end credits had a disclaimer stating "All voice and vocal impressions were performed by the cast and not by the actual celebrities themselves".

Cancellation

As a result of the show's poor performance, ABC president Fred Silverman severed all ties with Filmation and began commissioning its Saturday-morning cartoons from Hanna-Barbera, with which he had a working relationship during his time at CBS, and from Sid and Marty Krofft, whose Krofft Supershow would replace it on the lineup the next year. Though Filmation had had several series end after short runs, none had ever been cancelled before completing their runs up to that point. Filmation noted that the cancellation actually saved the studio money because ABC had already paid for a full season and now Filmation did not have to follow through on paying to produce the remaining episodes.^[9][11][4] In an attempt to save ratings, Filmation had planned to repackage the repeated Groovie Goolies episodes as a new segment, redubbed the Super Fiends (capitalizing on the title of rival Hanna-Barbera's Super Friends), but the show was shelved before the change could be incorporated. The animated segments were featured in the Filmation syndicated package, The Groovie Goolies and Friends, and also resurfaced in the home video market in the 1980s.^[11][4]
