Some Pok\u00e9mon have different variants. Usually, these are dependent on regions and can completely alter the Pok\u00e9mon; for example, the fire-type Pok\u00e9mon Ninetails has a variant form in the Alolan region that changes it into an ice\/fairy dual-type. These variants can also be purely cosmetic, however, such as with the Pok\u00e9mon Shellos. Here's how you can get your hands on either an East Sea or West Sea Shellos.

First, the main thing to keep in mind is that the Shellos variants are purely cosmetic. An East Sea and a West Sea Shellos offer no advantages or disadvantages over the other. West Sea Shellos have a pink and white color scheme while East Sea Shellos have a blue and green color scheme. Your Pok\u00e9dex can be completed with having only one of the variants registered, so you only need to worry about the specific Shellos if you have a color preference or are looking to add it to your personal collection. Screenshot by Gamepur A Western Sea Shellos can be found on the Western side of Mount Coronet, the mountain range that splits the Sinnoh region, and an Eastern Sea Shellos can be found on the Eastern side. A great place to catch a Western Sea Shellos is Route 205, which you'll pass through on your way to the Eterna City Gym. An easy way to find an Easter Sea Shellos is on Route 213, a route you'll take after completing the Pastoria City Gym.
