In the Cherokee version, the old couple, Kana'ti and Selu, had a son already, and Blood Clot boy formed out of the blood Selu washed into the river while cleaning the game killed by Kana'ti. He was like a feral child, and they named him I'nage-utasvhi (He Who Grew Up Wild). The two boys were great trouble-makers and were eventually turned out of the family by their parents. Their conversation in the sky is what makes the sound of thunder.
The Southern Ute story has obvious affinities with the Inuit story of Bear Woman and the Rabbit Boy of the Rosebud Sioux. The Cherokee version has close similarities to the story of Enkidu.
