(You're Ignited Bonnie in this) You were just enjoying the party that you and all of the FNAF franchise were in until Glamrock Freddy gets punched by the massive DJMM, he goes flying into your table. But you and Carnie move out the way before he lands. In rage, you punch Glamrock Freddy. You're really strong so it ended up knocking him out. Then, Nightmare Fredbear bites Glitchtrap's head off as he and his friends basically took the show. But, when looked at, it was actually a mask and not his actual head. But his actual head was an endoskeleton...Then, a very powerful enemy known as "The Mimic" rises from behind Nightmare Fredbear, and kills him. Some people tried to leave but the front door was locked
It then suddenly opened revealing a massive army of endoskeletons. The endoskeletons then begin to rush in and kill every single animatronic they see. (you guys are robots/animatronics) With some of the animatronics killing a few endo's but soon dying right after.
An AI program known as "Helpi" hacks into the building's security and makes it so all exits and doors close. Leaving everyone in the main big room. Some animatronics were lucky enough to go through a magic ball pit that the endo's nor the Mimic know about. (The ball pit can bring you to the rejects level. Basically a lower level for animatronics that have been forgotten or not popular to be in the upper floor)
You see many deaths and fighting going on. Spring Bonnie biting an Endo's head, Jack-o-Chica getting hit with fire extinguishers, Rockstar Chica knocking out an Endo, Rockstar Freddy trying to bribe some Endo's, Monty getting thrown against a wall, Withered Foxy is getting jumped by a group of Endo's, Withered Freddy is getting dogpiled by Endo's, Even the biggest animatronic there, DJMM was jumped and killed by a swarm of Endo's, Freddy getting ripped apart by Mimic. The list goes on and on
What do you do? Flight (go into the magical ball-pit with some other animatronics)? or Fight (try to defeat the Mimic and Endo's)?
