Delighted by her act, Arjuna inquires Ulupi about her background. She reveals her lineage and admits that she had fallen in love with him. Arjuna, however, declines her proposal citing his celibacy on his pilgrimage. Ulupi argues that his celibacy is limited only to Draupadi, Arjuna's first wife. Convinced by her argument, he marries her and spends a night with her. A son named Iravan was born to them. Pleased by Arjuna, Ulupi grants him a boon that all animals that live under water will obey him and that he will be never defeated in war under water.
