How to Catch (& Evolve) Shellos in Pokémon Scarlet and Violet

Just as their names suggest, East Sea Shellos and West Sea Shellos live in separate regions of the Paldea map in Pokémon Scarlet and Violet.

Shellos is Water-type Sea Slug Pokémon in Pokémon Scarlet and Violet that is unique in that it possesses two forms depending on the sea near which it spawns. More specifically, there are the East Sea Shellos with a bluish turquoise body and the West Sea Shellos with pastel pink skin. Besides the color, the Sea Slug’s appearance differs slightly between forms. The East Sea Shellos sports two horns and wing-shaped flaps on its back, while the West Sea Shellos has spikes on its back and a tentacled gill-like organ atop its crown. However, regardless of looks, both forms of the Sea Slug Shellos have the same IVs and Movesets.

First, to catch the blue East Sea Shellos, Trainers must explore the coastline corners of South Province in Pokémon Scarlet and Violet (Area Five) and East Province (Area One). Shellos is not a rare spawn, so players should have little trouble finding one on the sandy beaches of these two zones. Its level should also be relatively low, ranging from the early to mid-twenties. Trainers looking to weaken Shellos for a successful capture are recommended to use Grass- or Electric-type attacks but avoid using Water-type Moves. Water-type abilities do not harm the Sea Slug but instead boost its Special Attack.

Blue & Pink Shellos’ Location in Pokémon Scarlet and Violet

On the other hand, if Trainers are aiming to find and catch the pink-colored Shellos, they will need to search in a location on the western side of the Paldea world map in Pokémon Scarlet and Violet. According to YouTube content creator Underling Blessing, this alternate version of the Water-type Sea Slug Pokémon can be found on the beaches directly north of the trading hub of Porto Marinada, where players can also find Pokémon Scarlet and Violet‘s Dusk Stone. Keep in mind that the levels of the Wild Shellos roaming this zone will be notably higher than East Sea Shellos on the eastern side of the map.

Once Trainers have captured either variant of Shellos in Pokémon Scarlet and Violet, they can evolve it into Gastrodon by advancing the Sea Slug’s level to 30. Similar to how East and West Sea Shellos differ in appearance, the evolution forms of Gastrodon also vary depending on its form. Nevertheless, these differences are solely cosmetic and do not affect the performance of the Water-type pocket monsters in battle. Additionally, Game8 states that catching Wild Shellos can yield Shellos Mucus, a TM crafting material in Pokémon Scarlet & Violet for the moves Rain Dance and Earth Power.
