The Slender Man is a mythical being that comes to those who fear him. He is unaturally tall and has 4 arms. It is said that if you see the Slender Man even once, there is no way to escape him. He usually stalks his victims and slowly drives them insane before kidnapping them.
I bet Slender Man lives in that forest over there because he can blend in with the trees!
