The official name of the residents of the Small Country of Cameroon is the Pygmies. They have a total of more than 30,000 people and they are the oldest residents of Cameroon.

They are burly but have slightly black skin and unusually small heads. The average height of an adult man is only 1.2 meters. The highest is also difficult to exceed 1.
