Star Ball Rolling

Star Ball Rolling is one of the four minigames in Super Mario Galaxy, along with Bob-omb Blasting, Bubble Blowing, and Manta Ray Surfing. Mario rides on a Star Ball, which is, as the name implies, a ball with a Power Star inside. The goal is to roll the ball past multiple obstacles, including wandering enemies and voids, and into a hole to break the sphere and obtain the star.
