Glamrock Bonnie has returned to the Mega Pizzaplex while Monty was repaired at Parts and Service. But there seems to be a problem. He is possessed by William Afton. William Afton tried to take control of Glamrock Bonnie's mind but failed. The serial killer is stuck in the mind of a Glamrock Animatronic Rabbit as if he's trapped. As a result, these two will have to get along with each other, but there is a problem for these two: Vanny begins Glamrock Bonnie's journey as a killer robot, having managed to get out of Afton's control.
