In Pokémon Pokopia, Ditto can use Squirtle's Water Gun to water plants.
The game's central mechanic lets the human-form Ditto learn useful moves from Pokémon it encounters. These moves are adapted for practical world-building tasks rather than being presented only as battle techniques. Squirtle's Water Gun provides a direct way to hydrate plants and support cultivation.
This detail is distinct from the game's association between Bulbasaur and Leafage, which is used to add greenery to the environment. Both examples show how familiar Pokémon moves are repurposed as tools for restoring the landscape.
Water Gun is the correct move, not Surf or Hydro Pump. Those are also water-related Pokémon moves, which makes them plausible distractors, but the official game description specifically identifies Squirtle's Water Gun for watering plants. The mechanic helps connect each Pokémon's identity to a concrete building or gardening activity.
