What is the name of this Felix the Cat cartoon/film?

I'm trying to find a certain Felix the Cat cartoon. I've looked around on the internet, and for some reason I haven't been able to find much about this one. It's been a long time since I've seen it, but I seem to remember jellyfish, some kind of show, and a cat-girl standing onstage and singing to an audience. Does anyone know the name of this one, or am I confusing this with something else?
