Kinda humorous. The giant pit fiend would translate well into muppet form. I once had a nightmare where a watched through the perspective of a man as he died and the world shifted around him as he plummeted into a weird puppet hell. He fell onto a massive pile of puppets that kind of awoke and tore him to pieces. They were like a mix of muppets, that clown puppet from Poltergeist, and those super creepy monkey dolls from the 70s.
