This stage is pulled from Legend of Zelda: Ocarina of Time. If you venture west from Hyrule Field in that game you will arrive in a desert like area with a broken bridge covering a flowing river with a tall waterfall connected to it. That location and this location are one in the same!
In Smash Bros. however Koume and Kotake will randomly appear and affect the left and right side of the stage respectively. Koume will cause a rapidly spreading fire on the left side of the stage with her fire magic while Kotake will perform the polar opposite on the right side, freezing it into giant spike shaped glaciers. It is also worth mentioning that the bridge in the middle of the stage is not broken to begin with, it can be destroyed temporarily if it receives enough abuse.
