Uh, now concerning your safety, the only real risk to you as a night watchman here, if any, is the fact that these characters, uh, if they happen to see you after hours probably won't recognize you as a person. They'll p-most likely see you as a metal endoskeleton without its costume on. Now since that's against the rules here at Freddy Fazbear's Pizza, they'll probably try to... forcefully stuff you inside a Freddy Fazbear suit.
