The Paldean Wooper was one of the first Pokemon to be revealed for Pokemon Scarlet and Pokemon Violet. While Paldean Wooper shares its Ground-typing with its Johto counterpart, it loses the Water-typing for Poison-typing instead, thus making it a Poison/Ground dual-type Pokemon. This Wooper doesn't evolve into a Paldean Quagsire, but rather an entirely different species called Clodsire.
Unfortunately, the Water/Ground-type Wooper can't be found anywhere in the Paldean wild. However, there's exactly one Johtonian Wooper in Pokemon Scarlet & Pokemon Violet, and getting it involves trading. The trade itself isn't via the Pokemon Portal or Union Circle. Instead, players will want to take a Paldean Wooper to a certain city in western Paldea.
Where to Trade Paldean Wooper
Obtaining Paldean Wooper
Rookie trainers can catch the Poison/Ground-type very early in the game. The first sighting of Paldean Wooper is by the pond near the path between Los Platos and Poco Path Lighthouse. The Woopers here will be around level 5, meaning trainers can catch one before they even reach Mesagoza. For those that may have missed the level 5 Wooper, don't worry. Paldean Wooper also live in the southern part of Paldea and can be caught at any of the highlighted locations on the map in the image above.
The next step is to go to Cascarrafa. On the second level of the city (between Cascarrafa Gym, and the lower level by the Asado Desert), there's a fountain in the middle of the square. Here, there will be an NPC who will want a Paldean Wooper. (Players can read this in the yellow word bubble above her head.) Speak to her, and she'll ask if players want to trade their Paldean Wooper for a Johtonian Wooper.
As a traded Pokemon, the Johtonian Wooper is already nicknamed (Manchester). It is level 18, and will receive bonus EXP in battle. Unlike its Paldean counterpart, this Wooper will evolve into the Water/Ground-type Quagsire at level 20 instead of Clodsire.
How to Get More Johtonian Woopers
If for some reason players want another Johtonian Wooper, they will have to breed the Wooper they got from the trade. Unfortunately, it's not as easy as putting the traded Wooper with a Paldean Wooper. Trainers will need to make sure the Johtonian Wooper (or Quagsire) is holding an Everstone before taking it on a picnic with a Ditto or another compatible Pokemon. The Everstone will ensure that the offspring Pokemon is Johtonian Wooper and not the Paldean Wooper.
To increase the probability of Pokemon Eggs appearing, make sandwiches that have the Egg Power meal effect. Sandwiches that contain mostly sweet ingredients (such as fruit, peanut butter, whipped cream, or jam) will have Egg Power. Additionally, there are "sweet recipes" that players can get from the man at the Sandwich Stores around Paldea. For those that don't have time or the ingredients for crafting sandwiches, buy food from restaurants or ice cream stands. Each food item will have its effects listed.
Players should also keep in mind that having an Everstone on a Pokemon for breeding means that the parent's nature will be carried over to the offspring. So if the parent Johtonian Wooper has a Brave Nature, its child will have Brave Nature too. To change this, players can make a save file before they trade with the Cascarrafa NPC. If Wooper doesn't have the right Nature, then they can soft-reset. Alternatively, players can go to the Chansey Supply store and buy a Nature Mint. Trainers that don't care for Pokemon Natures or EVs won't have to worry about this.
Quagsire vs. Clodsire
Johtonian Wooper and Quagsire's stats are more well-rounded than their Paldean counterparts, who excel in HP and Special Defense. As a Water/Ground-type, Quagsire shares Clodsire's immunity to Electric-type moves. However, Quagsire and its pre-evolved form will take 4x damage from Grass-type moves. Most of Quagsire's learnset is made of Physical moves such as Slam, but its all-around stats mean that it can make better use of Special moves like Ice Beam.
Quagsire has a Type advantage over Clodsire, but it lacks the Special Defense that Clodsire has. It's also only a little faster than Clodsire and while its Special Attack is higher, Quagsire works better as a Physical attacker. It's likely that Scarlet/Violet trainers will get the Johtonian Wooper just for completion's sake.
Ultimately, it's up to players whether they want to keep a Johtonian Wooper/Quagsire on their final team. There are many Water-type and Ground-type Pokemon new and old in Paldea, so it's likely that Quagsire may be overlooked. It should also be noted that players do not need to get the Johtonian Wooper to complete the Pokedex, because Quagsire does not have a Dex Entry in Pokemon Scarlet and Pokemon Violet. Still, for lovers of this Gen 2 Pokemon, having Quagsire around is a nice touch.
Pokemon Scarlet & Pokemon Violet are available for Nintendo Switch.
