Frankie is one of Frieda the Foot's good friends. Like Frieda, he is a talking foot puppet. He speaks with an exaggerated Southern accent. He is notably the only male foot to make an appearance in the series.
Frankie has dark skin and light brown eyes. He owns a blue flip-flop shoe, but only wears it for one brief scene. Unlike Frieda and most of the hand puppets, he does not wear a hairpiece or any accessories.
Frankie appears in one episode of Oobi: "Frieda Friend!"
