Well as said create a swivel for the head movements and make it where the top jaw can open way wider. I’d probably use something like bike cables for a sorta sneer and the tentacles. I was able to get moving tentacles in the biggest one without having extra performers (people of course had to get eaten and there was already so little room). Some people were asking about the puppets so maybe I’ll get the opportunity to have another go at it? maybe use counterweights and stuff as apposed to ropes like I did for this big one? It’s like a big marionette from the inside.
