Abandoned Pools is a lonely area accessible through the floating orb in the Clash of Mutated Forms.
Features
The main area of this world has several large pools of water and several monoliths. There is also a huge waterslide that can be found, as well as a green barrier at the top of the map. One of the monoliths has a door on it. Entering the door will lead to the locker rooms where there are many humanoid statues scattered around. In between two of the statues is a floating blue square which teleports you to the Pink Desert.
