Mbh 3.176.1b

Then all those warriors having in due course happily lived at Badari for one month, proceeded towards the realm of Suvahu, king of the Kiratas, by following the same track by which they had come. And crossing the difficult Himalayan regions, and the countries of China, Tukhara, Darada and all the climes of Kulinda, rich in heaps of jewels, those warlike men reached the capital of Suvahu. And hearing that those sons and grandsons of kings had all reached his kingdom, Suvahu, elated with joy, advanced (to meet them). Then the best of the Kurus welcomed him also. And meeting king Suvahu, and being joined by all their charioteers with Visoka at their head and by their attendants, Indrasena and others, and also by the superintendents and servants of the kitchen, they stayed there comfortably for one night. Then taking all the chariots and chariot-men and dismissing Ghatotkacha together with his followers, they next repaired to the monarch of mountains in the vicinity of the Yamuna. In the midst of the mountain abounding in waterfalls and having grey and orange-coloured slopes and summits covered with a sheet of snow, those warlike men having then found the great forest of Visakhayupa like unto the forest of Chitraratha and inhabited by wild boars and various kinds of deer and birds, made it their home. Addicted to hunting as their chief occupation, the sons of Pritha peacefully dwelt in that forest for one year. There in a cavern of the mountain, Vrikodara, with a heart afflicted with distraction and grief, came across a snake of huge strength distressed with hunger and looking fierce like death itself. At this crisis Yudhishthira, the best of pious men, became the protector of Vrikodara and he, of infinite puissance, extricated Bhima whose whole body had been fast gripped by the snake with its folds.
