King Mungo-Mungo Coconuts Boonana XXXIII, commonly known as Mungo XXXIII, was the ruler of Monkey Land in Aison. He was descended from Mungo I and was the half-brother of Chee-Chee and father of Poko Moko Bling Bling Yoko. He had various adventures in Aison, including the Magestar, prior to the Yamatian Invasion while trying to find a way to save Monkey Land from a prophesied catastrophe. He drank some shapeshifting potion which turned him into a woman named Gekrepten so he could traverse the human lands and chat with people but he later got thrown in jail. Mungo presumably perished during the Yamatian Invasion.
