World 6-Rock World
Nearly all of this world takes place inside a cave or underground. There are several ledges, rock outcrops, and ridges to hold onto, shimmy across, and jump over.
While on thin ledges, Mario can either shimmy slowly with his back to the wall or hang from it with both hands and slide quickly left and right. Watch out for Bullet Bills, Stone Spikes, and Super Piranha Plants!
