Dive was added to Pokémon Pokopia in a free software update.
The update introduced the ability to move freely underwater, expanding exploration beyond the game's original land-focused areas. Dive also connects to new content associated with Bubbly Basin, an aquatic area included in the game's expansion material.
The addition reflects Pokopia's approach to progression: familiar Pokémon moves can function as practical abilities for exploring, gathering, or reshaping the environment. Dive is therefore more than a battle command in this game; it opens access to underwater spaces.
Surf, Fly, and Waterfall are other well-known Pokémon moves that can be associated with travel, which makes them plausible mix-ups. However, the update specifically named Dive as the newly added underwater exploration ability.
