Check out this cool minecraft adventure map I found! It's based on the game slender (have that to)!
Download link and original forum is located in the description of the video. And btw, the texture pack only changes the endermen to slendermen (captian obvious) and the villigers to....well that's for you to find out.
NOTE that I do not own this adventure pack. I am just a messenger (= All of the content is rightfully owned by the owner/ owners.
