It began with the sound of someone walking up the stairs and then there is a creak of a door. There is an old reel to reel projector, and the whole thing takes place in the attic. I'm pretty sure there is a bunny involved. It's at least partially live-action.

I think there is a bat (although that could be a separate show). If there is a bat, then the bat is curious about something and ends up getting electrocuted. They are talking about curiosity killed the cat.

I would have watched it in the 90s or early 2000s.
