Killer Santa

This is a short story that takes place in the late 1980's on Christmas Eve night. There's a family of three, a wife named Jennifer, a little girl named Tilly, and the husband named Jack. Jennifer tucks Tilly into bed, and tells her to get some good sleep for Santa to deliver the presents. Then Jennifer heads to bed with Jack. They decided to watch a movie in bed then Jennifer drifts to sleep as Jack finishes the movie. Right when Jack turns the tv off, he hears something outside. He gets up quietly, puts on his boots and coat, and checks to see what it is. When he gets outside and looks around, he gets hit on the back of his head knocking him out. When he wakes up, he finds himself in some type of toy factory. When he looks outside, he sees that he is at the North Pole. But there's a lot of things that seems off about the place.
