How to Get Cloyster in Diamond & Pearl

Cloyster never appears wild in these games. Hook a Super Rod Shellder, then apply a Water Stone, the same stone that finishes the Poliwag line into Poliwrath.

Wild Cloyster may be holding when caught:

Pearl (50% chance) A somewhat-small pearl that sparkles in a pretty silver color. It can be sold cheaply to shops.
Big Pearl (5% chance) A quite-large pearl that sparkles in a pretty silver color. It can be sold at a high price to shops.

Catch Shellder at any of these 3 spots to eventually evolve into Cloyster.

Fastest Path

The best route is Masuda Method, about 1 in 1,639 on each try.

Step 1 · Encounter Method2 in Diamond & Pearl

Masuda Method: Breed with a parent from a different-language game. Works on any breedable line.

Full Odds: Walk through grass, surf, or fish. Every encounter is its own independent shiny roll.

How many you have done, or plan to do.

10%lucky few173----
25%one in four472----
50%coin flip1,136----
90%very likely3,773----
How is this calculated?

Every encounter has the same shiny chance, the Shiny Odds Per Try shown above. Each one is a separate roll that does not care how many you have already done, so the more you hunt, the higher your overall chance of at least one shiny. The formula below turns your odds and your number of tries into that combined chance.

chance after N tries = 1 − (1 − p)^N,  where  p = 1 / odds per try

Example at 1 in 8,192 (classic full odds): about 864 encounters for a 10 percent chance, 5,678 for 50 percent, and 18,862 for 90 percent.

The table above flips that around: it shows how many encounters it takes to reach a 10, 25, 50, and 90 percent chance at your current odds. Turning on boosts like the Shiny Charm, sandwiches, or chains improves your odds, so the encounter numbers drop.

These are estimates, not promises. Most games have no pity counter, meaning no guaranteed shiny no matter how many you hunt, so even Very Likely is not guaranteed: some hunters find one early, others go well past that point.

Where these shiny odds come from: Read our full methodology

Cloyster Weakness

Cloyster's Water/Ice typing leaves it vulnerable to Electric, Grass, Fighting, and Rock. Cloyster's physical bulk (base 180 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Pokemon Diamond / Pokemon Pearl

Cloyster Diamond & Pearl Guide

  • Yes. Cloyster is a post-game Pokemon. You need to defeat the Elite Four and enter the Hall of Fame first. Cloyster becomes available after the main story is complete in Diamond & Pearl.

  • In Diamond & Pearl, use Cloyster as a hazard setter. Splits damage between physical and special. Speed is middling,

  • For Diamond & Pearl, build your team around Abomasnow. These have the highest co-usage rates with Cloyster in competitive formats. They cover each other's weaknesses.

  • For Diamond & Pearl, run Adamant on Cloyster. +Attack is what matters, and the -Sp. Atk cut doesn't hurt this set. Fits the hazard setter role.

Game Availability

One of the original 151, Cloyster has appeared in 20 games: most mainline games. From Red & Blue through the latest titles, it's rarely been left out of a regional Pokedex.
