Slenderman is a cold blooded paranormal killer. His tentacles could possibly be used for mobility or perhaps weapons. Were he is commonly sighted is the slender Woods. Bad children would go into the slender Woods an be chased by him until they we're either caught or went home an told there parents of there mischief. Here is a fact from a journal that was found an was dating back to 1702. "The tall man stoon in a clearing, dressed as a nobleman, all in black. Shadows lay over him, dark as a cloudy midnight. He had many arms, all long and boneless as snakes, all sharp as swords, and they writhed like worms on nails. He did not speak, but made his intentions know,". He is a chilling sight to see if you ever see him.
