Thanks! I always assumed it was the way the puppeteers hand was angled, similar to Kermit's head.

I thought it was a fabric finger loop inside the skull? Or at least that's the way Kevin Clash did it.

In Kevin's interview with the Archive of American Television, he said there's a wooden bar that the eyes are connected to.
