In Pokémon Pokopia, Squirtle’s Water Gun can water dried-up plants.
Pokopia reinterprets familiar Pokémon moves as useful abilities for restoring the world. After befriending Squirtle, Ditto can use Water Gun to provide moisture to plants that have withered in the barren landscape.
This is different from the move’s conventional battle role. Water Gun is normally a basic Water-type attack, but Pokopia makes it part of an environmental toolkit alongside gathering, crafting, planting, and construction.
Hydro Pump and Rain Dance are also water-related moves, which makes them plausible alternatives in a quiz. The specific move named in the game’s official description is Water Gun, and the Pokémon connected with that example is Squirtle.
