Mbh 1.129.9

Then that oppressor of all foes, decked in celestial ornaments, received the adorations and blessings of the snakes, and saluting them in return, rose from the nether region. Bearing up the lotus-eyed Pandava from under the waters, the Nagas placed him in the selfsame gardens wherein he had been sporting, and vanished in his very sight.
