The 5000-year-old Gena works in a zoo as an attraction. In his spare time, he plays the garmon and likes to sing. His two best-known songs are "Pust' begut neuklyuzhe..." and "Goluboy vagon" ("The Blue Train Car").
One rainy day, which happens to be his birthday, Gena sings the song "Пусть бегут неуклюже пешеходы по лужам..." ("Let the pedestrians run clumsily over puddles..."), which contains the famous line: "Such a pity that one's birthday happens only once a year."
