He is controlled by the second player and can join or leave the game at any time. Due to his deuteragonistic role, Mugman formerly could not be controlled by the first player.

Retrieved June 4, 2018.On Inkwell Isle, Cuphead and his brother, Mugman, are two fun-loving children who live under the watchful eye of Elder Kettle. Despite Elder Kettle's warnings, the brothers wander off to the Devil's Casino and begin playing craps. When they go on a winning streak, the Devil appears and makes a deal, offering to give them all the money in the casino if they win the next roll and threatening to take their souls if they lose. Cuphead accepts the offer but loses by rolling snake eyes. As he and Mugman beg for mercy, the Devil offers them another deal: if the brothers can collect the "soul contracts" from his runaway debtors by midnight the next day, the Devil might spare the two. Cuphead and Mugman return to Elder Kettle, who gives them a magic potion that allows them to fire blasts of energy from their fingers, but also warns them that the debtors may not turn in their soul contracts willingly.
