Falling Falls is a level in DK: Jungle Climber and the first level of the world Chill 'n' Char Island, the fourth world in the game. The initial area of the level consists of a large waterfall, which has to be climbed using continuously falling Pegs. The rest of it is made up by a vertically scrolling cave and a few areas full of Brambles. In the later parts of the level, a rough blizzard is taking place, which is constantly pushing the Kongs to the left, making it harder to progress.
