Here’s a notion of what some of the puppets might look like — the idea being that they’re made by cave-people, so they’re not super high tech. The head might be made of wood, we think, unlike that frickin’ amazing neanderthal puppet head that Neanderthaler posted… rock would be mighty heavy for us weak-but-clever modern humans.
Bone would be cool though. The idea is that the heads are kind of like maraca-style rattles, so they make a maraca-style-rattle sound when you move them about, and they can double as maraca-style rattles if need be. Their mouths don’t move, we think. Or maybe they do. Maybe they’d be better if their mouths moved. Less primitive, but more expressive.
