I’m gonna explain this in particular, carefully. Of course don’t click on the spoiler tag if you don’t want the plot for Fazbear World 2 spoiled, since the game wasn’t finished and was really pointless until the final boss. Anyway yeah just here:

During a harvesting of wood a sudden vortex appeared over the sky, this vortex sucked all of Fazbear Worlds animatronic inhabitants out of it. Upon entering an alternate dimension Freddy wakes up and finds him self isolated, no sight of life anywhere. He decides to investigate the strange area and eventually found himself running into Plushtrap, a being from another planet that’s from the same dimension as Freddy, Plushtrap has been hunting down a fugitive which took a precious orb, if used for the wrong doing it can cause absolute chaos, Freddy decides he has no one else to trust besides Plushtrap and the two travel to find the fugitive and also save Freddy’s friends in the process. Our main antagonist here, Nightmare Golden Freddy, has 99% of Fazbear Worlds inhabitants trapped in a crystal which he will use to supercharge the orb allowing him to become more powerful than before so he can take over his homeplanet from the other dimension (Not the one the nightmare world is in obviously). He orders his minions to slow down Plushtrap and Freddy from reaching his castle, but that doesn’t stop the duo from getting there. Upon arrival Golden Freddy and the duo of Freddy and Plushtrap have a showdown, in the end Golden Freddy is defeated and plays fair and sends them home. Upon coming back everyone comes to their senses and rejoice as they are safe and sound with Freddy & Plushtrap to thank, after having a small party FredBear comes from the forest with the orb Plushtrap was seeking originally thinking it was some rare treasure, however, he let that thought go after Plushtrap told him what it was and FredBear gave the orb back to Plushtrap. Plushtrap thanked everyone and had a small talk with Freddy before departing from their world. Plushtrap exited their world, and went back to his. However, far away a robot named Coffee told his master that they had found the orb and it was on the planet “Earth.” Coffee asks why they need it and his master simply says “Only time will tell…” and the game cuts to a The End screen.
