After Happy Days Gang failed, ABC still stuck to their guns and released the Laverne and Shirley cartoon the following year, which failed even faster. The year after that, Mork and Mindy got a cartoon (this time, following Robin Williams' Mork as a highschooler). He had a pet spiderdog. Mork and Mindy, though more popular than the other two animated adaptations, still wasn't terribly popular but it got the most episodes of the three.
They extended the show to an hour-long format, adding Laverne and Shirley to the second half with two new characters. By then, one of the two actresses (Penny Marshall, I think), detecting a sinking ship, jumped overboard, quitting the show. They got some other bitch to play her character for the Mork/Laverne cartoon (Penny played the character when Laverne was its own, standalone cartoon).
Those two new characters? Well, in an attempt to attract more kids, they introduced the Fonz and his talking fucking dog to the L&S segments. He worked for the army somehow. After eight or so episodes of this setup, the show was canned altogether. No Mork. No Mindy. No Laverne. No Shirley. No Fonz. No talking fucking dog.
Supposedly, there are unaired episodes and we don't even know their names nor how many there are. I can't stress enough how no one gives enough of a shit to find them. There's even one episode that we do actually know the name that may have aired but there's such little interest that no one is even sure if it ever did. Imagine being so thoroughly ignored that no one gives a shit to even keep track of whether an episode even aired at all.
I amend my prior mentioning of Happy Days Gang as a forgotten cartoon since the Mork and Mindy one was so thoroughly forgotten that I didn't even remember it existed until you brought up the Laverne/Fonz cartoon.
