While cleaning up the animation for “Jose’s Dinner”, I was having a bit of trouble with the character’s mouth. I told it to open, but it still appeared closed.

It turns out that when I duplicated him and didn’t use the duplicate, I forgot to erase it. So there was a duplicate right underneath. What I was seeing was the closed mouth of the duplicate inside. It was as though he had eaten himself! Once I fixed this, it explained some of the problem I had been having and now, he was able to open his mouth!!
