I think that fazbear frights isn't canon

But you can make theories about any fnaf character

Ok

I think pit Bonnie's a demon that found one of the springbonnie suits and used the ball pit to time travel to the future.

Fazbear Frights stories are representations of characters in the main series.

Example: To Be Beautiful is a representation of Elizabeth.

I think Pit Bonnie and Scraptrap could be the same suit

I think pit bonnie was created by travelling in the suit, causing william afton and the suit to fuse together into one creature.

I think the nightmares are a version of the funtimes (Funtime Bonnie real)

okay, here's an old theory of mine from when i first got into fnaf : golden freddy doesn't own the suit, but the pizzeria. this would be supported by the poster that appears in the hallway in fnaf 1 and the fact that he was able to write on the logbook (which precisely belonged to the pizzeria in fnaf 1). I don't know if this is still valid, since in UCN we see golden freddy creating a whole hell

That sea Bonnie’s are actual things
