"The Slender Man" is a human-like monster who is extremely thin and tall, who seems to be wearing a black suit and tie. His arms and legs can stretch to impossible proportions and he can extend tentacle-like appendages from his back. He has no face, nor hair. He stalks children and is believed to kidnap them. After seeing the Slender Man, it's not long before you're taken.
He waits and watches quietly from the woods or from outside your window; sometimes bravely venturing inside your home. He is more often seen at night than during the day and when photographed, he is often seen near children.
