This is the last batch of headcanons I promise the next chapter WILL be a oneshot

Sometimes when Evan had a nightmare and couldn't sleep alone anymore, he'd go to Mike's room and sit on his bed until they were both awake. Once they were both awake, they'd sit and talk (albeit quietly) about how they were doing, rant about nightmares, maybe tell a mildly spooky story or two, until Evan was calmed down and happy enough to go back to sleep.
Most of the time, he couldn't even make it back to his own room and would just sleep in Mike's bed, so they'd spend the rest of the night together, and if either of them woke up again during the night they'd simply rinse and repeat.Mikey should be wearing glasses, but thanks to a combined effort on William's cheap ass and Mike's rebel ass, he does not. He can't see very well farther than eight feet, and can't see at all after twelve.
All the dead kids' funerals were closed-casket because the bodies were never found. Evan's body was available, but it was a closed casket because... Well, obviously.
Mikey loves indie/bedroom rock, Evan is an emo, Elizabeth and Vanny love hyperpop, William liked classical music, and Carol liked whatever was popular.
Due to William's extensive profit on animatronics, the Aftons had a HUGE house. Like. Everyone had an entire FLOOR to themself. Mikey even had a whole room filled with arcade cabinets, from the Fazbear restaurants, that ended up unpopular and unplayed. Charlie also had one of these. Unfortunately, this led to the emotional and physical separation of the family members, which led to even more of a chaotic, unhealthy environment.
But hey, they were the perfect family, right? They had so much money, they MUST be happy! ...?Mikey can't speak for himself, not after the fire that killed him. It destroyed his throat and vocal cords. His only vessel to speak through is GlamFred, and he's not very fond of it. But as he's written in INaBF (shameless self-promo wooooh), he was sort of blessed with possessing GlamFred of all the animatronics in the world; he wouldn't relocate for anything.
Carol could and did speak French. Because of this, all the Afton kids know a bit of French and Michael, due to spending literal days at a time with Carol sometimes, is nearly fluent.
Crumbling Dreams (the song Ballora's music box plays) was an actual song Mrs Afton sang while she was alive. The lyrics were made by William in the production of Ballora, but the song was written and sung by Mrs Afton. So when Mikey crawled through Ballora Gallery he was just there like "WAIT A MINUTE"
Ballora treats the Mini-rinas like her own children. She sometimes even dressed them up in tiny doll outfits (left behind by careless children) to go and walk around CB'S PW like human guests, before it got shut down for "gas leaks."
Carol was bisexual leaning toward women; Elizabeth was a baby lesbian; William was a pansexual leaning gay; Michael was a bisexual KING.
