I'm not going to lie... When I first saw this thing, I thought it was fake. I mean it looks like it was done in ms paint.. lol
However, this thing is a hallucination that can occur in Five Nights at Freddy's 2. Several youtubers have been encountering it
in their playthroughs. There seems to be video evidence of its existance, and well as pictures. How it goes into your office is currently unknown. The thing behaves in sort of a similar fashion to how Golden Freddy behaved in the first Five Nights at Freddy's... If you don't put your mask on as soon as you see it in your office, it will cause your game to crash..

I would also like to note that little plate puppets of it, as well as Shadow Freddy and BB can be seen in Party room 4, seen here: http://img2.wikia.nocookie.net/__cb20141113224156/freddy-fazbears-pizza/images/5/51/148.png



Anyways, this skin is 1.7.9+ exclusive.
