How to find and catch Pokémon Cloyster?

Pokémon Cloyster can be found near any body of water, including ponds, rivers, seas, and swamps. You can catch near fountains, pools, and water parks in the city of Cloister.

Cloyster appears only infrequently on the map. It is possible to obtain it by evolving a Pokemon Shelder or catching it at an event.


Cloyster is a black bivalve mollusc. It is protected by a light-gray shell that is encompassed by a second jagged, blue-violet shell coating. It has one barb-like spike extending from above its head, and its outer shell is covered with conical horns. Its shell is tougher than a diamond, and its spikes are even harder; the size and sharpness of these spikes are affected by strong tidal currents. It features two white eyes and a mouth on its pearl-like face. Its interior anatomy, other from its face and skull, has never been seen. It is difficult to open its shell from the outside once it has closed itself in. This formidable protection enables it to resist anything from a bomb explosion to a missile attack.

Cloysters usually only open their shells to attack an opponent. With its shell securely closed, it is completely capable of retaliating against any adversary. It fires its spikes at the enemy in quick succession, repelling them. Clamp was Generation I’s trademark move. It swims using the same projectile technique that it employs to shoot its spikes. It eats saltwater and then ejects it backwards, propelled by siphon-jet propulsion. Cloyster, the consequence of Shellder developing via an Evolution stone, is seldom encountered in the wild, however it may be found on the sea bottom, tucked amid rocks and coral; yet, it will aggressively chase Slowpoke tails on land. Gastrodon is related to Cloyster and its pre-evolved cousin, Shellder. Cloyster’s natural predator is Kingler.
