Explained simply
Pokémon Pokopia is a life simulation game in which players explore, build and interact with Pokémon. Its Pokédex is the in-game record of Pokémon players encounter, and new areas and creatures give them more to discover.
The Bubbly Basin expansion adds an underwater area and new ways to explore it, including diving and improved surfing. It is part of a planned three-part paid expansion; a separate free update adds building and storage features for all players.
The story matters to players deciding whether to buy the expansion or return for the free update. It also gives an early look at how the game’s world and activities may grow over time.
