What a serpentine rabbit hole I just now emerged from!
The entry point was at the conclusion of a filler show on OETA today (PBS affiliate) about Native American arts in OK, when this one guy was talking about how he was able to bring native perspective into his works which included the animated Star Trek show.

The example shown was an episode featuring a Native deity-based entity (based on the Mayan feathered serpent) called Kukulkan, which evoked my memory of a kiddie program which also featured a serpent puppet playing opposite a puppet named Kukla. I just HAD to go look that up. That was Oliver J. Dragon, the snaggletoothed puppet called Ollie for short, backstory of which goes back to being born in Vermont.

Both were accompanied by a human lady, Fran, and was produced by somebody we should all know but don't: #BurrTillstrom. He's the guy that launched #JimHenson down his own puppeteering rabbit hole.
