A weird creature who calls himself "Koyemshi" and becomes the children's tutor after Kokopelli's disappearance. He is able to communicate verbally, and is usually very sarcastic. He responds to the children's call, and is able to teleport them, as well as others from the outside world to the cockpit, and vice-versa. However, he cannot teleport directly between two places, and must go through the cockpit beforehand.
