In the ongoing human tradition of imagining worlds beneath the surface, The Pokémon Company invites players to descend into something new — an underwater town where familiar creatures tend bubble-wrapped crops and coral lights the way through dark sea floors. Launching August 5, 2026, the Bubbly Basin expansion for Pokémon Pokopia on Nintendo Switch 2 arrives alongside a free update that unlocks the Dive move, fundamentally reshaping what the game's world can contain. It is a small but telling gesture: that the act of building, of tending and connecting, need not stop at the water's edge.
