Cloyster Locations and Availability

Finding Cloyster depends on the specific game version you are playing. In many titles, the most efficient method is to catch a Shellder and use a Water Stone. However, some games provide direct encounter opportunities.

Generation I and II Locations

In the original Pokémon Red, Blue, and Yellow, as well as the Generation II titles Gold, Silver, and Crystal, Cloyster is obtained exclusively by evolving Shellder. This pattern continues through much of the series, including Ruby, Sapphire, and the HeartGold and SoulSilver remakes.

Modern Generation Locations

In Pokémon Black and White, as well as their sequels, Cloyster can be found in Route 13, Undella Bay, and Humilau City. Players exploring the Galar region in Pokémon Sword and Shield can locate the Pokémon in the Dusty Bowl, East Lake Axewell, and the Stony Wilderness. In Pokémon Scarlet and Violet, Cloyster inhabits the various Paldean Seas surrounding the region.
