Jatasura Abducts Yudhishthira, Twins, and Draupadi
While Bhima is away hunting, the rakshasa Jatasura — who has been living among the Pandavas disguised as a brahmana — assumes his true form, seizes their weapons, and abducts Yudhishthira, Nakula, Sahadeva, and Draupadi. But Sahadeva manages to extricate himself and runs to summon Bhima.
The Pandavas lived comfortably on that mountain. The rakshasas who had been troubling them had left, and Bhima had gone to roam around as he willed. It was then that a rakshasa abducted Dharmaraja Yudhishthira, the twins Nakula and Sahadeva, and Draupadi.
He had been living among them for some time — disguised as a brahmana skilled in mantras and well versed in weapons. He had served the Pandavas every day, waiting for his chance. He was known by the name of Jatasura. He had been covetous of their quivers and bows, and he had waited.
When Bhimasena, the destroyer of enemies, went out to hunt, Jatasura assumed a different form — distorted, terrible, gigantic. He grasped all the weapons. He seized Draupadi and the three Pandavas and fled.
But with a great deal of effort, Sahadeva extricated himself. Shouting for Bhimasena, he ran in the direction the immensely strong one had taken. Aranyaka Parva, Chapter 451
