Who is the kidnapper?
In Five Nights at Feathers, we are introduced to the story of a kidnapper luring 4 children into a back room, and presumably killing them. Then, during the night, the animatronics come to life. One theory is that the kidnapper could be you because the animatronics are after you if it is true that their souls are possessing the animatronics as their bodies could not fit inside. This theory seems to be the most valid theory so far. Another theory is that the kidnapper could be the Phone Guy, after all, you do work for him, and the animatronics hear his voice during the phone calls, so its possible that it could be him.

Fifth Animatronic?
A secret fifth animatronic hallucination was cancelled, but many believe that it could still be canon to the storyline, meaning there is a fifth child to go along with it.
 * -|FNAFE2=Five Nights at Feathers 2 introduced us to a LOT of new lore related material that would set the stage for the third game.

Is this game a prequel?
Yes, it is. The game reveals that the owners will reuse the location for the new one. They also have animatronics like Toy King Pig and Toy Steg. And if Five Nights at Feathers 1 is a prequel to this game, why aren’t they mentioned or seen in said game or the third one?

Who Killed Phone Guy?
This was believed to be one of the withered animatronics. How? Well, the withered animatronics are most likely other victims of the kidnapper that are possessing the animatronics. The only dupe in this theory is that the calls could be live, instead of pre-recorded, making the theory impossible.

The Kidnapper struck at this and the previous location
This theory explains why the stuffed-animatronics walk around, however it doesn’t explain why they are after you or who the kidnapper is, as you play as a different person in Five Nights at Feathers 2.
 * -|FNAFE3=Five Nights at Feathers 3 marked the answer to so many questions in the series, like that the animatronic Cardi was the one who killed Phone Guy due to his scream.

Who is Cardi and where did he come from?
Cardi and Silver Dillo were both the very first stuffed-animatronics ever made. The kidnapper hacked and used Cardi, but could have also used Siver Dillo due to him walking around, to lure his first victim. He might have also used the animatronic for the second location’s killings, but not the killings in Five Nights at Feathers 2 or Five Nights at Feathers, as Cardi is never seen in game.

The Kidnapper works for Feathers Entertainment
This is a plausible theory, as we don’t know who created the Dual animatronics; it could be the kidnapper.
 * -|FNAFE4=While Five Nights at Feathers 4 won’t have a lot of information on the Kidnapper himself, it will dive in deeper to how the souls of the kids are possessing the stuffed-animatronics. More will come soon when the game is released.
