As you meet new Pokémon in Pokopia, these little guys will teach you how to do new moves that make building towns and terraforming the desolate wasteland a breeze. One of the more monotonous chores you’ll have to do as you fix up this world is water dried-up soil and plants with Water Gun, which only covers a set five-square area. It’s tedious, but worth doing if you want to grow crops and altogether improve the environment for Pokémon. However, one Pokémon will teach you a technique that shortens the amount of time it takes to wet the parched earth from hours down to seconds.
Paldean Wooper is one of the Pokémon you can encounter in the Bleak Beach area. It will show up if you can make a Marshy tall grass habitat, which consists of four squares of yellow tall grass next to muddy water. Once you get this little guy in your town, you’ll unlock a quest in which Piplup asks about creating a waterfall by sucking up water from sources like lakes or the ocean and dispersing it elsewhere, and suggests that you ask Wooper for help. The poison/ground Pokémon will teach you how to stockpile gallons of water in your body similar to how you suck up items on the ground. Once you’ve learned how to use this ability, you’ll use it to make the waterfall Piplup requested, but the ability has plenty of other practical uses, especially if you have a large area of dry land you want to cover in water in a short amount of time.
Dropping off gallons of water on flat ground will allow it to disperse over a large area. At first, it will appear to flood the space, but you can suck it right back up and the ground will still be moist. This can revive dead plants, make dry soil usable for planting crops, and altogether help you make a town not look like a barren wasteland. You’ll also receive points toward challenges for watering the ground, all while barely having to lift a finger.
A lot of your time in Pokopia is spent learning how to more efficiently get things done. Sometimes solutions come when you unlock new abilities like this one; other times it’s just about figuring out little ways to speed things up like cutting down crops instead of picking them one by one. The game is full of secrets like this because its systems are so reactive, but it doesn’t always go out of its way to tell you about them, so it’s worth experimenting with Ditto’s various abilities and seeing what works.
