A shallow sea off the coast of Pueltown. Many kinds of Pokémon make their home in its crystal clear waters. Crossing the seafloor are fast-moving currents that swiftly propel swimmers.
It is a calm, peaceful ocean area with deep chasms, which can be crossed using Mantine's Field Move, and fast-moving undercurrents which can be used to catch fast-moving Pokémon. The player is first sent here to retrieve a key to the bridge between Pueltown and Altru Park which later is taken by a Sharpedo. To catch up with it, currents are to be used. Land-based Pokémon cannot come here for obvious reasons and will wait for the player to come back up.
