This is something to tell to puppet when spring trap was still a good guy he had a daughter he build his own animatronics so that other children would have fun he would not let his daughter go to the circus baby animatronic tho one day she didn't listen and the animatronic killed her and Calvin was his son actually he died then so spring trap did not think it was fair for him to lose 2 children so he killed the children he thought it was fair that the other parents had lost someone too that's why he killed you and the children
