Which Pokémon move lets the player water plants in Pokémon Pokopia?

Water Gun lets the player water plants in Pokémon Pokopia.

The player controls Ditto, which can befriend Pokémon and learn their moves for practical uses in the environment. Water Gun is associated with Squirtle and allows Ditto to refresh plants that need water.

This system turns familiar Pokémon moves into tools for world restoration. Other learned abilities serve different purposes: Leafage can help create greenery, while additional moves allow Ditto to cut debris or smash rocks. The move-based design makes Pokémon relationships directly useful to construction and habitat work.

Water Gun is not the same as Rain Dance or Hydro Pump. Those are also water-related Pokémon moves, but Pokopia’s official gameplay description specifically identifies Squirtle’s Water Gun as the ability used to refresh thirsty plants. Ditto first encounters Squirtle after helping it recover from dehydration.
