Mixels involves many different, fun-loving tribes—each tribe having a different color scheme—who inhabit a fantasy land of adventure and wonder. They can Mix (combining two Mixels), Max (combining all three Mixels of the same tribe), and Murp (when a mix goes horribly wrong) in all kinds of situations, using the mysterious Cubits. All that stands in their way are the small, evil, discolored Nixels led by the tall King Nixel.
