The Yeti, sometimes known as the Abominable Snowman, is a mysterious ape-like creature rumoured to live in the Himalayan mountains. Despite numerous expeditions into the remote mountain regions of Russia, China and Nepal, the existence of the Yeti remains unproven and UNEXPLAINED!
The Yeti is rumoured to be muscular, covered with dark grayish or reddish-brown hair, and weigh between 200 and 400 lbs. It is often depicted in popular media to have white colour hair to help it hide in the snows of the Hmialayan mountains.
