A rather large-like river that leads out into the ocean, and leads through the whole island. This is where the Magikarp come every year - their birthing place - to lay eggs and thus travel up stream, through a waterfall and harsh rapids to the top of a moutian, where a lake waits at the top. At night, they evolve and travel back into the ocean. During the rest of the year, many Wingull and Peliper are seen picking at the stragglers, or those who were unable to make it to or from the ocean, as well as a few other wild Pokemon who live on the island.
