The Waterfall Cavern is partially hidden in the back of the Cliff area, behind a rather large waterfall. Throughout this cavern, miniature waterfalls pour down from above, most likely from small tunnel-like holes that lead down from the water slide located above the cavern. There is a rather ragged climb ahead for anyone trying to reach the Cavern of Hearts by traversing this area. Be prepared to fight Heartless as you climb ever higher in this cavern.
