How to Get Clamperl in Ruby & Sapphire

Clamperl is a surf-only catch, four common spots across two deep-water spots, levels 20 to 35. You will need Surf and a little luck, since it stays out in the open sea rather than near shore.

Wild Clamperl may be holding when caught:

Blue Shard (5% chance) A shard from an ancient item. Can be sold cheaply.

2 Methods
Shiny Odds

Both methods here share the same odds, about 1 in 8,192 on each try. Pick whichever fits how you play.

Step 1 · Encounter Method2 in Ruby & Sapphire

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

Breeding: Hatch eggs of this line; each egg rolls at the base shiny rate (no Masuda before Gen IV).

How many you have done, or plan to do.

What To Expect
ChanceEncountersTime
10%lucky few864----
25%one in four2,357----
50%coin flip5,678----
90%very likely18,862----
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.

Clamperl Weakness

Type-wise, Clamperl takes extra damage from Electric and Grass. It resists 4 types, giving it decent defensive coverage. Clamperl's physical bulk (base 85 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Pokedex Entry

CLAMPERL’s sturdy shell is not only good for protection - it is also used for clamping and catching prey. A fully grown CLAMPERL’s shell will be scored with nicks and scratches all over.

CLAMPERL grows while being protected by its rock-hard shell. When its body becomes too large to fit inside the shell, it is sure evidence that this POKéMON is getting close to evolution.

Clamperl Ruby & Sapphire Guide

  • Clamperl evolves into Huntail via trade. Trade needs a Game Boy Advance link cable and a second GBA running another Gen 3 game (FireRed, LeafGreen, Ruby, Sapphire, or Emerald). Trade Clamperl to a friend, then have them trade it back. The 2026 Switch re-release supports the same trade through local wireless on the Pokemon Center 2F Wireless Club, with no cables required. The Deep Sea Tooth must be held during the trade. Bring one over from a sibling Gen 3 game if needed.

  • Yes. Wild Clamperl in Ruby & Sapphire can hold Blue Shard (5%). Use Thief (TM46) or Covet to swipe the held item without affecting your catch chance. Quickest way to farm rare items like Blue Shard.

Game Availability

Clamperl has been available in 13 games since Ruby & Sapphire, though obtaining it requires a trade evolution. This extra step makes it less common than Pokemon found through standard wild encounters.
