A Waterfall Climber is an enemy from the game Virtual Boy Wario Land, only appearing in Stage 6. They somewhat resemble real life tadpoles, although with a large pair of horns. Waterfall Climbers can be found in the waterfall area of the stage, where they sit on rocks. When Wario approaches, they jump up and begin to swim within the rush of the waterfall. If left alone, they will continuously swim up and down the waterfall.
They can be defeated by either a Barge or a simple bump to its side, which will send the Waterfall Climber flying off-screen. However, they cannot be touched while they are swimming on the other side of the waterfall, when only their bellies can be seen. When they pause to look through the waterwall, they can be safely stomped on to defeat them. Although in this position, Wario will be harmed if he swims underneath them, while their horns are exposed.
