Oh yeah - that was the whole point! The hand “holding” the pot is fake, I got it from the dollar store. My real arm exits my shirt sleeve at the elbow, obscured by a black sleeve to hide it a bit, and goes through the back of the pot and up through a layer of foam “dirt” and into the puppet.
The fake arm looked a little wonky but as long as I stood straight forward nobody really figured out what I was doing until the Audrey II started moving and snapping. That freaked a lot of people out, it ruled.
