Which Pokémon move lets Ditto water dry plants in Pokémon Pokopia?

In Pokémon Pokopia, Ditto uses Water Gun to water dry plants.

Ditto learns moves from Pokémon it befriends, turning familiar Pokémon abilities into practical tools for rebuilding the environment. Water Gun is associated with Squirtle in the game’s promotional material and helps refresh plants that need water.

This system changes how moves function compared with traditional Pokémon battles. Instead of being used primarily to damage an opponent, a move can become part of the player’s construction, gardening, and habitat-restoration toolkit.

Water Gun is easy to confuse with other Water-type moves such as Bubble Beam, Rain Dance, or Aqua Jet. Those moves are part of the broader Pokémon move catalog, but the specific ability described for watering plants in Pokopia is Water Gun.
