The Vampire.

My granddaughter (2 and 1/2 at the time) looking up finally unafraid of my Treat Room Vampire in 2007.
I have video of this guy somewhere; the moment I find it, it's posted. The deal was, you walk into the room, and there's a treasure chest of treats, with this guy standing off to the right, looking down very disdainfully at you, shaking his head and grunting his displeasure at not being able to eat you then and there... then, just as you take a treat, a giant, fanged, LED-red eyed bat comes screeching up (loudly!) from behind the treasure chest, and you run screaming out of the room, killing the treaters in line behind you.
Yep. Good times.
