Gnarly Bones is one of the two skateboarders in Island Xtreme Stunts. He is found practicing in a skate park. If you go up to him, he asks you if you want to race him. If you accept, you must beat him to the next skate park on a specific course. The course is less difficult than Gnarly Shugu's course, as there are no jumps. If you run into him while racing, he knocks you back. The path goes through the tunnel under the mountain, then down a street up to a side alley which goes to the docks and police station and from there to the skate park. If you win, you get his Card.
The appearance of Gnarly Bones is a Skeleton with a Dude Hat.
