The youth learns the languages of dogs, birds, and frogs. Through this knowledge he makes his fortune. The father drives him out for his stupidity and orders him killed, but a compassionate servant substitutes an animal's heart and lets him escape. By means of his knowledge he cures a sick princess or discovers a treasure (cf. Type 613 III b, c) and marries a princess. Later a bird indicates his election as pope (king). Often mixed with Type 517.
