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.

How to Get Shiny Muk in Let's Go Pikachu & Eevee
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
Let's Go Pikachu & Eevee Shiny Muk Calculator
2 MethodsThe best route is Catch Combo at full boosts, about 1 in 274 on each try. Tune it below.
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 many you have done, or plan to do.
| Chance | Encounters |
|---|---|
| 10%lucky few | 29 |
| 25%one in four | 79 |
| 50%coin flip | 190 |
| 90%very likely | 630 |
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.

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.
| Damage | Types |
|---|---|
| 2x (Weak) | Ground, Psychic |
| 0.5x (Resist) | Grass, Fighting, Poison, Bug, Fairy |
Muk Evolutions
Muk is what Grimer becomes, and it doesn't evolve any further. The evolution from Grimer pushed Muk to 500 total stats. Sp.Def saw the largest single gain at +50. View every chain in the Evolution Chart.
How to Evolve
Let's Go Muk Best Moveset
105 Attack and 105 HP with 100 Sp. Def on Poison. Without AbilityPoison Touch adding poison chance on contact, the moveset is straightforward physical Poison TermStab. Decent bulk and power at 50 Speed, but too slow to threaten anything that controls the pace.
Best Build

Brave raises Attack and lowers Speed. Madam Celadon sets this nature when you pick Red, then Pink. It costs 10,000 Pokedollars and lasts for the rest of the day.
Candy for Muk
Grimer Candy raises every stat, but only Grimer and Muk can eat it. The stat candy that goes with Muk is Health Candy (HP) and Mighty Candy (Attack), and any Pokemon can eat it; Health Candy L needs level 30, Health Candy XL needs level 60, Mighty Candy L needs level 30 and Mighty Candy XL needs level 60 or higher.
Alolan Form
- Alolan Muk

Alolan Muk (Poison/Dark type) has 105 HP, 105 Attack, 75 Defense, 65 Sp. Atk, 100 Sp. Def and 50 Speed, 500 in total. Weak to Ground. Resists Grass, Poison, Ghost and Dark. Immune to Psychic. Alolan Muk is not found in the wild in Let's Go. In Let's Go Pikachu, give a Grimer to a person in Cinnabar Island to get a level 44 Alolan Grimer, then evolve it into Alolan Muk.
