Don Pianta, also known as the Don of Untimely Death, is the boss of the Pianta Syndicate as well as ruler of the West Side of Rogueport. Don is the father of Francesca and the rival of Ishnail. His skin is orange, he has a mustache, and he wears a dark suit, dark sunglasses, and a gangster-style fedora in addition to the traditional Pianta hula-skirt.
Mario must visit him in order to acquire tickets to the Cheep-Cheep Blimp, in order to reach his destination, Glitzville. Don Pianta agrees to supply Mario with the tickets needed under one condition, that he find his missing daughter and his most trusted henchman Frankie, who have eloped. After Mario locates them at the docks, Frankie and Francesca confront the mob boss. Through Mario's intervention, Don Pianta gives the couple his approval, and rewards Mario and co. with the tickets he promised.
