When I was a kid, I was watching Looney Tunes cartoons on a CD and saw a scene that I can't find. At first it seemed to me that the notes were flying, but I can't remember exactly. But I remember a wooden fence with a hole through which an eye peeked out. After that, the episode "Hair-Raising Hare" begins, so I assume that this episode or clip was from the same animated series. Has anyone seen this scene, or do you have it, or is it just my childhood imagination and false memories?

Edit: I don't remember if it was notes, but I remember something falling down and it looked like some kind of transitional or musical segment, like credits or an intro
