This Barbershop quartet consists of four singers from Steamland.
They are seen in "Freak Out!" when Alva Gunderson sends them to Beans' room in his penthouse so serenade her with a lovesong. Bean, who just before already received a postcard and flower petals from a courier send by Alva, is not amused and runs away. One of the singers calls her to come back, and promises they have two more songs in their repertoire.
