The 3rd theory I have is the purple man popping up on to your screen in a very shaded figure, with his telephone and a badge. (sadly I could not get a picture but just look him up on google you'll see a couple.) He acts like Golden Freddy in the original, with him limply sitting there near the left vent... but with the description I gave instead. Later on this was also proven fake and was photo shopped.
