The protagonist would go over to bonnie bowl, they would go to the bonnie bowling stage and hear sounds coming from the stage, bonnie would jump out and push you.You run to the bowling ally, you turn around and see bonnie take of his head and roll it at you, you would half to kick his dislocated head into a wall. At one point his face would get stuck into the wall. bonnie would then go to collect it, while this is happening, the endos wound then activate and you would have to throw bowling balls at them and they would then be destroyed then bonnie would chase you around the bowling ally and keep throwing his head at you until it knocks down the pins and his head would get stuck behind the pins and then his body would power off doing to low battery to his head because if his head is disconnected his body shuts down. (also bonnie has a dislocatable incase his head accidentally falls off during bowling, this is something that freddy says).
I hope you liked this also I think this would be a cool mechanic for bonnie bowl how bout you?
