You were a technician at the new and improved Freddy Fazbears Pizzeria. You were in charge of making sure all of the state of the art animatronics were functional. It wasn't necessarily a hard job, just tweaking some servos or replacing some wires.
That was before the new foxy model got torn to pieces by the kids. You had to constantly go back in and fix her everyday. Eventually, your manager just said to leave her in that state as a tear apart, put back together attraction. Now all of your coworkers refer to it as "The Mangle."
The pizzeria is closed today so you go in to repair the bots. Everyone is fine, except Chica, whose beak fell off but you simply reattached it. You then go and check on Mangle. There she is, her voice box glitching and picking up radio frequency as she lays like a pile of scrap heap. You can't help but feel bad for her.
