Pikachu-exclusive Muk brings pure Poison bulk in Let's Go, and its Alolan Poison/Dark form from trading is immune to the Psychic hits that would otherwise threaten it.

Is Muk Good in Let's Go Pikachu & Eevee Playthrough?

Only in Let's Go Pikachu. Muk has solid HP and Attack but arrives too late and Poison typing doesn't help against the Elite Four lineup. More of a personal favorite pick than a strategic necessity.

In Let's Go Pikachu & Eevee, the strongest route to a Shiny Muk is Catch Combo, which reaches about 1 in 274 at full boosts. Shininess carries through evolution, so hunting an earlier stage and evolving it counts too. Pick a method and tune your setup below to see live odds. Compare Shiny Muk odds across every game

Fastest Path

The best route is Catch Combo at full boosts, about 1 in 274 on each try. Tune it below.

Step 1 · Encounter Method2 in Let's Go Pikachu & Eevee

Catch Combo: Catch one species back-to-back. A Lure stacks on top of a 31-plus combo.

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

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

Muk Weakness

Ground and Psychic moves hit Muk for super-effective damage. The Poison typing picks up 5 resistances to work with. Muk's special bulk (base 100 Sp.Def) helps absorb special-type weaknesses, though physical moves exploit the lower Defense.
