There's another childhood fear of mine that I forgot to mention before: The piano monster from Super Mario 64. It scared the living CRAP out of me when I was little, and I always feared having to get that red coin that was behind it. I was also (to a lesser extent) freaked out by that Chain Chomp in Bob-Omb Battlefield. I would literally jump whenever it suddenly lunged out at you. A lot of people say that Bowser's laugh and the eel in Jolly Roger Bay scared them, but those never bothered me.
