Monkitropolis is the fourth world in Super Monkey Ball Adventure, and is where Prince AbeABE resides. It is a dark, New York-like city with cars and unicycles that can be obstacles to the player. Its other areas include a speedway with a Noise Factory that is used to annoy the Kongri-lan "monsters". It is dark and appears to be as if it were evening. The reason for this is that monkeys of Kongri-La tied down the sun to keep the residents in the underwater city warm. The residents of Monkitropolis hate the Kongri-lans due to them blaming each other for their cities' problems.
Along with Kongri-La, the kingdoms' lands form a yin-yang symbol.
