Muk

Muk is a Poison-type Pokémon in Pokopia. You'll see it most reliably when Marsh fishing spot habitat is in place, with visits clustering around all day and sunny, cloudy, and rainy conditions.

Muk is rated Rare. Rare rarity rewards a dedicated habitat and patient repeats. Even with the right materials in place, visits cluster around specific time-of-day and weather windows, so plan the in-game day around them.

To keep Muk returning, lean into the Litter specialty when laying out the habitat — Pokémon in Pokopia respond to matching gameplay loops more than to raw decor count. If a listed habitat isn't built yet, check the habitat guide cards below for the exact materials and placement notes; Muk usually shares its preferred habitats with a small cluster of related Pokémon, so the build pays off for more than just one entry.

Other Pokémon you'll see at the same habitats as Muk include Grimer and Clodsire. That overlap is why we recommend planning habitat builds around a cluster rather than a single entry: once the materials for Marsh fishing spot are placed, you're effectively staking out spawns for the whole group at once, which is the fastest way to grow the Pokédex without redoing crafting work.

Muk is the evolved form of Grimer in the wider Pokémon series. Pokopia does not include an evolve action, so attracting Muk means matching its own habitat conditions on this page — Grimer stays a separate dex entry with its own attraction route.

Use the favourite toggle on this page if Muk is on your current dex priority — favourited entries surface in the planner's long-term goal list, and the habitat cards below link straight to the build recipes that gate the visit.
