Yeah, you've never heard of it? It's an internet meme, I think it started back in... 2009ish. Apparently it started from a paranormal picture contest on Something Awful.
[He turns onto his back, his one free hand moving to hold the blanket up slightly, if only to keep it from smooshing up against his nose.] The challenge was to make a photo creepy and submit it. Some guy made a couple of photos with kids in them, and he manipulated the picture to make it look like they were being stalked by this thing with long arms and legs, and no face. After that, people started to make a story about the character, put him in more pictures, made up some Creepypasta on him, and Slenderman was born.
[After that little story, Teddy turns his head to give a half smile.] I guess it got so popular that someone made a game out of it.
