What is "ulupi"

Ulūpī or Uloopi (also known as Uluchi or Uloochi), is a character in the Hindu epic Mahabharata. The daughter of Kouravya, the king of serpents, she was the second among the four wives of Arjuna. She also finds a mention in the Vishnu Purana and the Bhagavata Purana.

Ulupi is said to have met and married Arjuna when he was in exile; she had a son with him, Iravan. She played a major part in the upbringing of Babruvahana, Arjuna's son with Chitrāngadā. She is also credited with redeeming Arjuna from the curse of the Vasus by restoring his life after he was slain in a battle by Babruvahana.
