Cuphead and Mugman are the protagonists from “Cuphead”, created by StudioMDHR. They both have cups for heads. Which is why the game is called Cuphead. You see, the subtitle is "Don't Deal With The Devil" because Cuphead and Mugman, the protagonists from "Cuphead", created by StudioMDHR have made a deal with the devil. Which is why the subtitle for the game is "Don't Deal With The Devil". Isn't that neat? I have a hernia
