Not entirely sure why, but I didn't find this one as creepy as your others. I think the ones that have some major turning point where things are clearly progressing, but highly off-kilter (like the scene after Skitzo kills the rich ostrich in "Spare a Dime?") are the most effective — where it feels like something "else" has taken control of the story and is perverting it.
However, at the same time, your choice of music was absolutely perfect for this one. This cartoon, out of all of the others, sounded the most like an old 1920s-era short.
