Willy's Wonderland DVD (Mass)

An unnamed drifter strikes up a deal with the owner of a family entertainment center to become it's night shift janitor in exchange for the owner's mechanic to repair the drifter's car. While inside, strange things start to happen in the abandoned center at night, such as animatronic mascots coming to life - with the aim of killing anyone on their path. Yet the janitor doesn't seem fazed or threatened at all.
