The Warden (Kurt) has this huge metal "claw" thing that covers his entire right arm. But sometimes, it alternates between being on his right arm and left arm. It depends on which way he's facing. This is because Climax just flipped the sprite for facing opposite directions. But it really looks weird when it changes position several times in a single scene. (Example: Pay close attention to it during the scenes where the Warden is in the lab talking to the Doc.)
