Squirtle’s Water Gun can refresh thirsty plants in Pokémon Pokopia.
Pokopia turns familiar Pokémon moves into practical tools for cultivation. After befriending Pokémon, Ditto can learn their moves and use them to alter the environment. Squirtle’s Water Gun supplies water, making it useful for plants that need refreshing during the habitat-restoration process.
This mechanic differs from the usual battle presentation of Water Gun. In Pokopia, the move is part of a peaceful construction and gardening system rather than an attack command in a Pokémon battle. Other learned moves have similarly practical effects, including creating greenery, cutting debris, and breaking rocks.
Squirtle is also important early in the plot. Ditto finds Squirtle suffering from dehydration and helps it recover. That encounter connects the story’s environmental crisis with the game’s central idea that Pokémon abilities can help rebuild a healthy world.
