Pretty interesting find, I don't know if this has been pointed out before, but I thought I'd leave this here.

One of the characters in one of Scott's old films resembles that of Circus Baby's original design. This character happens to be the sister to the character in this film who looks like the crying child, with the curly hair and, same outfit, and the 1out of place hair to go with it. Very interesting. Same hair style, hair color, hair tie color and eye color. Also worth mentioning that there is a similarity with the main cast of the games characters and the main cast of the movie's characters, also living in the same afton house we seen in FNAF 4, with even with the caretaker of the kids in this film to fit the description of our Movie William Afton in terms of outfit, but what do you guys think? Let me know your thoughts!
