Their homeland is Noki Bay, a small, tropical area with crystal clear water. When Eely Mouth`s plaque made the water dirty, an elder Noki helps Mario clean the water. Most of the Noki people live underwater, and not on land, and ride small jellyfish. They wear conch shells, and the babies wear snail-like shells. They are a peaceful people, and help Mario by teaching him to use the deep sea helmet, ane rewarding him with things like ropes to climb to a higher area, and even the Red Coin Fish.
