That’s from Will Vinton, the guy is a legend in animation. He created the CAlifornia Rasins and The PJs (a show on Fox in the 90s voices by Eddie Murphy)

He sold his studio to Phil Knight (Nike) and Knight’s son runs it, and recently produced Kubo and the 2 Strings.

Hey it was the 70s - there was a lot of weird animation back then - look up “Frank Film” from 1973
