Mbh 1.165.4a

“Of huge body and great strength, of red eyes, red beard, and red hair, he was terrible to behold, and he came, pressing deep the earth with his tread. The opening of his mouth, was from ear to ear and his ears themselves were straight as arrows. Of grim visage, he had a forehead furrowed into three lines. Beholding Bhima eating his food, the Rakshasa advanced, biting his nether lip and expanding his eyes in wrath. And addressing Bhima he said, ‘Who is this fool, who desiring to go to the abode of Yama, eateth in my very sight the food intended for me?’ Hearing these words, Bhima, O Bharata, smiled in derision and disregarding the Rakshasa, continued eating with averted face. Beholding this, the cannibal uttered a frightful yell and with both arms upraised ran at Bhima desiring to kill him, there and then. Even then disregarding the Rakshasa and casting only a single glance at him, Vrikodara, that slayer of hostile heroes continued to eat the Rakshasa’s food. Filled with wrath at this, the Rakshasa struck, from behind with both his arms a heavy blow on the back of Vrikodara, the son of Kunti. But Bhima, though struck heavily by the mighty Rakshasa, with both his hands, did not even look up at the Rakshasa but continued to eat as before. Then the mighty Rakshasa, inflamed with wrath, tore up a tree and ran at Bhima for striking him again. Meanwhile the mighty Bhima, that bull among men had leisurely eaten up the whole of that food and washing himself stood cheerfully for fight. Then, O Bharata, possessed of great energy, Bhima, smiling in derision, caught with his left hand the tree hurled at him by the Rakshasa in wrath. Then that mighty Rakshasa, tearing up many more trees, hurled them at Bhima, and the Pandava also hurled as many at the Rakshasa. Then, O king, the combat with trees between that human being and the Rakshasa, became so terrible that the region around soon became destitute of trees.
