Destructoid has published a complete guide to the Bubbly Basin Pokédex in the game Pokopia, listing every Pokémon that can be found in the game's only underwater region. The guide is aimed at players trying to fully complete their Pokédex, since Bubbly Basin hosts a distinct set of aquatic and water-type Pokémon not found elsewhere in the game, requiring specific Habitats to be built to attract and befriend them.

According to the article, there are 50 Pokémon to discover across the Bubbly Basin region, including species such as Shellder, Totodile, Mudkip, Popplio and their respective evolutions. For each entry, the guide details the required Habitat (such as coral congregations, swaying flower beds or muddy playtime areas) and the Pokémon's associated Specialities, which range from abilities like Water, Chop and Crush to Teleport, Hype and Bulldoze, giving players a full reference for building out the necessary habitats to catch them all.
