I have noticed a lot of stupid things which really debunk a lot of otherwise good theories. So I wanna debunk them. I am a simple man.
BB and SpringTrap
We all know your audio devices in FNaF 3 are BB's sounds. There are actually 2 things I see that I just need to eliminate as possibities. The two misconceptions are: SpringTrap goes to murder the child, or BB and SpringTrap are linked. These a wrong. The Fazbears Fright building is a horror attraction, and you are working at it. The purpose of BB's sounds was too creep people out, not lure something. And SpringTrap is an animatronic, and in FNaF2 we discovered they are attracted to sound BB's voice is sound that is why he moves to BB's voice!
