-DISCLAIMER- I am NOT retaining everything to the vague as hell story of the FNAF series. It is my own representation specifically so that the story can work. All original work belongs to Scott Cawthorn. If anyone has thought of this before this was published, please understand that I did not know about it until after it was mentioned.
Here, we have our four animatronics. Freddy, Bonnie, Chica, and Foxy. As they rest this night, they will all be snared into nightmares, and encountering their shadow counterparts. They all have mistakes from their past they need to face. But how will they? These encounters will decide whether they fly off into the heavens like balloons, or stay trapped in their eternal hells. The Balloon Trials contain more than you'd think would happen in just one night...
-ANOTHER DISCLAIMER- Please don't try to take my idea as your own. If you mention this series, or want to make your own version of this series, be sure to ask me first and give me credit. I've seen too many people go through that copyright crap, and I don't want it here.
