[Dark because of FNAF's backstory]
There have always been rumors around Freddy Fazbear's Pizza. One day Rainbow's friend Gilda from the Everfree Academy dares her to spend a night at the infamous pizza place. Incidentally, Sunset was working as the Night Guard at the restaurant. Due to the circumstances, she will have no choice, but to introduce her two groups of friends to each other.
But first, she and the animatronics need to deal with this "thief" that sneaked into the restaurant.
