Below the surface resides a robotic testing facility where stylized animatronics called funtimes reside.

You are Funtime Freddy, and you share your stage with Funtime Foxy, the duo of the Funtime Auditorium, you two are good pals

You are deactivated in your stage and so is Funtime Foxy, the facility has been deactivated for some time, until a loose wire escapes the ceiling and falls inside your case opening, triggering your systems

You bolt to life, in your side is Funtime Foxy, but she felt and is in the floor, deactivated, the facility is a bit torn as well
