When a sailor can't bear life on ship any more, he jumps overboard and swims to a big barren rock. There he cares for a half-drowned cockerel and plants rice, hiding away when a boat arrives. The sailors are amazed to see rice growing and keep coming back, leaving plants and game-birds, until the island bursts with tropical fruit and wildlife. But soon the Queen of Portugal hears about it and demands to meet the person responsible.
