I'd been wondering about this for a while now. I was reminded again tonight and had time to look on the internet and get an answer. The answer = Rudolph the Red Nosed Reindeer, the old animated Christmas movie that uses stop motion animation. I knew one of the old, classic, animated Christmas movies had a monster in it. The monster in Rudolph is Bumble, the abominable snow monster. Boy, did he scare the crap out of me when I was a kid.
