So I was playing FNaF 2 Demo the other day, and was at the main menu when I saw something flash on and off the left bottom corner of my screen.
I waited, and watched hard, until I noticed the pattern. Whenever Toy Chica does its thing and momentarily turns into Old Chica, I saw something.
Waited again, and pressed PrintScreen. Ctrl+V in Paint, and voila. I blew up the image, and something was there, but I couldn't make it out.
So I uploaded to Imgur, and will post link here. There will porbably be a couple of links, because I don't know which one is setup for Wikia pages.
