You're just doing your job as the night guard, and suddenly a lot of Bonnies show up. There's Original, Toy, Bon Bon, Rockstar, Shadow (or RWQFSFASXC), Nightmare, even Glamrock!... basically all of them. Including Springtrap... that might cause a problem...

Rockstar Bonnie: "I'm going to plunge my guitar through your heart-"

Toy Bonnie: "Are you the night guard?"

Nightmare Bonnie: "... What-"

Springtrap: "Yeah, I killed those bastards. And I'd do it again, too!"

The rest stares
