This is a mug shaped like a Mugato, a dangerous alien from the science fiction Star Trek original series. The Mugato is an indigenous simian-like beast, carnivorous, with characteristically white fur, a rhino-like horn on the top of its head, and sharp and extremely venomous fangs. This mug is one in a set of six mugs including Captain Kirk, Dr. McCoy, a Gorn, a Klingon, Mr. Spock, and a Mugato.
