Aside from acting in the film, Jones also performed Trumpet Girl, whom she unofficially named "Dolores."
“I did a little bit of puppet work on the movie. There was a scene where they needed Muppet extras and there were not enough people because it was the end of the night. So I was like, I'll do it! They were so cool and they let me do it. But it is really hard to hold your arm up like that. I had cramps in my hands the next day from operating the mouth.”
