The killer robots in the Five Nights At Freddy's franchise are loosely based on the animatronic characters found at theme restaurants like Chuck E. Cheese's and Showbiz Pizza Place, but the real robots don't eat people.
However, it's easy to imagine Chuck E., Helen or Mr. Munch going crazy on the patrons when they start having uncontrollable robo-spasms that look like the stuff of nightmares.
Luckily they're usually bolted to the stage, giving kids a head start when the animatronic characters turn into psycho killing machines...
Never mind the countdown, these animatronic characters look creepy whether they're functioning properly or not!
