How to Get Shiny Cloyster in Black 2 & White 2
Cloyster arises from a Masuda-bred Shellder and a Water Stone, a route that keeps the 1 in 1,024 shiny chance. Compare Shiny Cloyster odds across every game
Black 2 & White 2 Shiny Cloyster Calculator
2 MethodsThe best route is Masuda Method at full boosts, about 1 in 1,024 on each try. Tune it below.
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.
| Chance | Encounters |
|---|---|
| 10%lucky few | 108 |
| 25%one in four | 295 |
| 50%coin flip | 710 |
| 90%very likely | 2,357 |
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.

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.
| Damage | Types |
|---|---|
| 2x (Weak) | Electric, Grass, Fighting, Rock |
| 0.5x (Resist) | Water |
| 0.25x (Resist) | Ice |
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)
