MONSTER OF BHUTAN

The Stewa Rutu was a water creature in the folklore of Bhutan.  It was credited with magical powers.  It had the stomach of a cow and tentacles.  Once an official put an elephant into the water to see what would happen.  After an almighty struggle, the elephant emerged, the stewa rutu still clinging to it.  Some local women finished the creature off with hot sand.  Whether there was only one such animal or a population, I have been unable to discover.
