Five Nights at Freddy's - Purple Hat!

I don't see why people are saying this has to do with Purple Guy. It has to be Shadow Freddy since he was purple.

Anyway, I would continue my duties of brightening and all that, but it's already been done.

Except one thing. On the bottom right there's a message that says "Property of Fr-------------------er". The subreddit thinks it might be "Fredbear's Family Diner".

If it is, then two words.
PREQUEL.
CONFIRMED.
