Once the cowherds led by Balarama and Krishna were grazing the calves on the the bank of the Yamuna. A demon appeared there disguised as a calf, to kill the divine brothers. Krishna pointed it out to Baladeva, and slowly approached him. In a trice, Krishna seized him with his hind legs along with the tail, and vigorously revolving him, threw him atop a kapittha tree (Kapittha is a fruit with medicinal properties). His life went out, as did his disguise.
Vatsasura fell, along with the kapittha fruits that dropped from the tree. The boys hail Krishna.
