So later on, some idiot decided that it’d be a neat idea to make a horror attraction based on the missing kiddies and stuff, so he got ,what I think was the original pizzeria, made it creepy, and decided that he needed at least 1 animatronic to actually get customers. Luckily for him, the man himself inside a heavily damaged bunny suit was in the very location, of which afton probably used to his advantage and acted functional. Now of course, nobody knows that the animatronic with the smell of a decaying corpse knew that it had a decaying corpse inside of it, except our good pal Mike, and went to work there, survived his own psychotic father, and burnt the entire place down, thinking he freed the spirits of everyone. Now somehow, Afton survived, and was able to degrade his entire design somehow, and also told Mike before he eventually got spring locked that his sister was still somewhere down in the basement or something.
Now considering fnaf 6, the puppet had seemed to escape, and re posses all the animatronics that were burnt down in the fire, into the Funtime animatronics somehow, since she had to literally be lured into a machine that was designed to catch her, yet did nothing but make her appear like Freddy, but that’s later. Now considering all the animatronics were put inside robots since before they were even teens, their mentality degraded, of which caused Mikes own sis to fool Mike into entering the scooping room, of which all the Funtime animatronics went to, combined themselves into one entity called Enard, and scooped out all of Mikes insides with the scooping room’s functions, and were finally human for around 30 years from their death.
