Whitered Bonnie

You were working as a Security Guard at Freddy's Fazbear pizza, one night, you were watching the camera monitor as always, you heard a noise in the hallway, at first you didn't give it any importance, but the noise became closer, when you lowered the monitor, You see an animatronic blue rabbit, it was missing its face and an arm, it stared at you until it finally spoke, its voice was audible "Y-y-y-you're not W-w-william Afton?... R-r-right? ..."

(It's optional how you want the story)
