The ocean Biome is an expansive body of water in which many Water type Pokemon can be found.
|Ocean||A very big, flat open biome made entirely of water, with underwater reliefs such as small mountains and plains and usually includes sand and clay at its bottom. Ocean biomes can go down to 30 blocks deep and the occasional island may exist, as a small version of other biome types. Entrances to underground ravines can be also found at the bottom of the ocean, as well as Abandoned Mine Shafts (whose upper parts are mostly flooded due to the proximity of the ocean). Oceans can be larger than ten thousand blocks wide and long.||Water, Sand, Clay.||Squirtle, Shellder.|
