Mbh 2.17.4b

And impelled by force of fate, the female cannibal united the fragments for facility of carrying them away. And, O bull among men, as soon as the fragments were united they formed a sturdy child of one body (endued with life). Then, O king, the female cannibal, with eyes expanded in wonder, found herself unable to carry away that child having a body as hard and strong as the thunder-bolt. That infant then closing his fists red as copper and inserting them into its mouth, began to roar terribly as rain-charged clouds. Alarmed at the sound, the inmates of the palace, O tiger among men, suddenly came out with the king, O slayer of all foes. The helpless and disappointed and sad queens also, with breasts full of milk, also came out suddenly to recover their child. The female cannibal beholding the queens in that condition and the king too so desirous of an offspring, and the child was possessed of such strength thought within herself--I live within dominions of the king who is so desirous of an offspring. It behoveth not me, therefore, to kill the infant child of such an illustrious and virtuous monarch. The Rakshasa woman then, holding the child in her arms like the clouds enveloping the sun, and assuming a human form, told the king these words,--O Vrihadratha, this is thy child. Given to thee by me, O, take it. It hath been born of both thy wives by virtue of the command of the great Brahmana. Cast away by the midwives, it hath been protected by me!
