Which Pokémon move lets Ditto water crops in Pokémon Pokopia?

Water Gun lets Ditto water crops in Pokémon Pokopia.

Ditto learns abilities by interacting with other Pokémon, and Water Gun is associated with Squirtle. In Pokopia, the move is adapted from a battle technique into a practical world-building tool: Ditto can use it to provide water for plants and crops.

This is part of the game’s larger design, in which familiar Pokémon moves have everyday construction or farming functions. Instead of using only conventional tools, the player relies on Pokémon abilities to collect resources and improve the environment.

Water Gun is easy to confuse with Surf, Water Pulse, or Bubble Beam because all are Water-type moves. However, the crop-watering function shown for Ditto is specifically tied to Water Gun. Surf has a different role in traversal, while the other moves are not the named farming ability in this case.
