From Bulbapedia, the community-driven Pokémon encyclopedia.
Deep-Sea Current (Japanese: しんそうかいりゅう Deep-Sea Current) is a Friend Area in Pokémon Mystery Dungeon: Red Rescue Team and Blue Rescue Team. It is obtained by recruiting Lugia. It is in the Northern Sea, and has a capacity of one Pokémon.
It is a platform deep under the water. The name "Deep-Sea Current" is a reference to the ocean current that was formed by the Legendary Birds' ceaseless fighting in The Power of One.
Legend says this deep, dark place, where a current flows, is home to the guardian of the sea.
