It is located in the same desert that Klinkerton is located in. It is a small place with visible pathways that lead into each other. In the center is a giant keyhole-shaped door that transports the Mixels.
After a long quest, the Klinkers, 2015 Frosticons, Lixers, 2015 Glorp Corp, and Munchos find themselves and all the other Mixels and background Mixels (except for the Weldos) to be there. All of them enter the keyhole door, and it disappears, leaving just the pathways.
- It is unknown what occupied the area before King Nixel's plan went into action. However, it is known that after, the city of Mixopolis was built on the site of it.
- The majority of the episode, A Quest for the Lost Mixamajig takes place in the desert surrounding it.
- Among the Mixels gathered there are the Klinkers Max, the Glowkies Max, the Orbitons Max, the Munchos Max, the 2015 Frosticons Max, a small part of the Fang Gang Max, a small part of the Flexers Max, the Lixers Max, and the Cragsters Max, which is strange because of the fact that most, if not all, of the Mixels making up the maxes were singular Mixels such as: Globert, making up a part of the Glowkies Max yet appearing on his own, Seismo, another Chosen One but somehow appearing while making up a part of the Cragsters Max, and all of the 2015 Frosticons which are also somehow responsible for their Max.
