Cuphead and his brother Mugman are two fun-loving children who live on the Inkwell Isle under the watchful eye of the Elder Kettle. They are both the main characters of the Cuphead Don't Deal With The Devil video game and a Netflix series called The Cuphead Show. In the game, despite the warnings of the Elder kettle the brothers wander off to the Devil's Casino and begin playing craps. Tricked into losing the game they are forced to repossess the souls of runaway debtors as a payment for the loss. A fanart Cuphead progress bar for YouTube with Cuphead and Mugman.
