(I feel like Bear's eyes would have Alpacas, Llamas, or Hedgehogs.)
When Bear rewatched this scene with me, she shared how she understood it...
"It basically got so hot that she started popping corn."
...which helped me realise that it's actually a button that turned into butter...
A documentary with scenes with the filmmaking team talking about these gags and the writers working out the story as well as the comedy!?
PS: I wonder if the multiple ear piercings is a nod to Zoey identifying as being part of The Alphabet Mafia.
PPS: I also was nudged by an idea to put together a 4x6 collage of images of films Bear and I both enjoyed. Maybe 4 films might be put in a frame. Though I would have wanted something that doesn't involve glass.
