The Mountain Jew is a small, almost human creature which vaguely resembles a cross between a goat and a human Jew. It dwells in the rocky mountain outcrops of the Himalayas. They are widely renound for the fluid they create which is drained and sold as a popular soft drink. This drink is commonly known as Mountain Dew and is most commonly found in the USA.
