Nixel, Nixel, Go Away

"There it is... Mixopolis, my town. A city in spectacular living color. A city of mixing, for mixing. Here, Mixels would mix at the drop of a Cubit. The city was colorful and bright, and was always gleaming with new mixing possibilities. Mixopolis was my town, and it always would be. But then, things changed."

- Booger
