According to the tales of my mother and my grandmother (in my childhood days down in Alabama), Yahooty (or maybe Yahootie) hid behind things in the refrigerator and turned the light out when you closed the door. He's about as busy as Santa Claus, trying to take care of refrigerators all over the world. I wonder if he has to monitor car doors, microwaves and all the other automatic lights??
Tread is pretty much right also - he's whatever you want him to be.
