Pokémon Pokopia charmed the pants off of everyone when it was released back in March, becoming a bona-fide system seller in the process. Just like all other areas, the point here is to attract various Pokémon by building their favorite habitats. This is part of the Pokémon Pokopia Expansion Pass, which costs $35, and there's no way to buy Bubbly Basin on its own. For the uninitiated, Pokémon Pokopia is an absolute blast. The Switch 2 exclusive is a weird mish-mash of Pokémon, Minecraft, Stardew Valley and Dragon Quest Builders.
