Kalmashapada

While hunting, Saudasa kills a rakshasa whose companion vows revenge. Disguised as Vasishtha, the rakshasa tricks the king into serving human flesh to the real sage, who curses him to become a man-eater for twelve years.

When Saudasa raises water to curse Vasishtha in return, his wife stops him, and he lets the water fall on his own feet, which turn spotted. From this he is called Kalmashapada, spotted foot.
