The Bowser UnWorld Territories is a country in the UnWorld. It is ruled by Bowser. He uses the land for testing powerful weapons and devoloping them. Also, some people from the Koopa Empire, also ruled by Bowser live in the cities here. Little people live outside cities because most of the land is jungle and beasts like Goombas and Pickles. Derpsticks also roam the wild here. The Territories has a population of 12,697,791,097, most of which lives in the South Africa Prefecture.
