Flavor Text

: A toxic fluid seeps from its body. The fluid instantly kills plants and trees on contact.
: It’s so stinky! Muk’s body contains toxic elements, and any plant will wilt when it passes by.

: They love to gather in smelly areas where sludge accumulates, making the stench around them worse.
: A toxic fluid seeps from its body. The fluid instantly kills plants and trees on contact.
: From Muk’s body seeps a foul fluid that gives off a nose-bendingly horrible stench. Just one drop of this Pokémon’s body fluid can turn a pool stagnant and rancid.
: This Pokémon’s favorite food is anything that is repugnantly filthy. In dirty towns where people think nothing of throwing away litter on the streets, Muk are certain to gather.

: The stench it gives off will make your nose scrunch up. Still, there are Muk fans who think that’s a good thing.
: After recent environmental improvements, this Pokémon is now hardly seen at all. People speculate that it may go extinct at some point.
: Their food sources have decreased, and their numbers have declined sharply. Sludge ponds are being built to prevent their extinction.
: Because they scatter germs everywhere, they’ve long been targeted for extermination, leading to a steep decline in their population.
