I don’t know the specific name of this puppet. I got him for Christmas one year when I was a kid, probably around 1980 or so.
The “illusion” is that the owner (wearing a white garden glove) is holding a small, furry critter. The secret is that the white glove is actually stuffed and sewn to the top of the critter’s head, while the owner’s hand is actually inside the critter. The illusion is pretty convincing, and I remember tricking a few of my friends into thinking, at least for a moment, that I was actually holding some sort of crawling critter.
Occasionally people would incorrectly guess that the critter’s legs were motorized. Sometimes I would try on purpose to make the movements look jerky. About the time they guessed it was robotic I would make the critter leap toward them. Got ‘em, every time.
I found this guy in a box labeled “puppets” out in my garage while doing some spring (fall) cleaning. Sadly, it appears my hand will no longer fit inside. Time to pass this one along to the next generation.
