Pokedex Entries
| Game | Entry |
|---|---|
| Red | Thickly covered with a filthy, vile sludge. It is so toxic, even its footprints contain poison. |
| Blue | Thickly covered with a filthy, vile sludge. It is so toxic, even its footprints contain poison. |
| Yellow | Smells so awful, it can cause fainting. Through degeneration, it lost its sense of smell. |
| Gold | They love to gather in smelly areas where sludge accumulates, making the stench around them worse. |
| Silver | Its body is made of a powerful poison. Touching it accidentally will cause a fever that requires bed rest. |
| Crystal | As it moves, a very strong poison leaks from it, making the ground there barren for three years. |
| Ruby | 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. |
| Sapphire | 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. |
| Firered | It is usually undetectable because it blends in with the ground. Touching it can cause terrible poisoning. |
| Leafgreen | Thickly covered with a filthy, vile sludge. It is so toxic, even its footprints contain poison. |
| Emerald | It prefers warm and humid habitats. In the summertime, the toxic substances in its body intensify, making MUK reek like putrid kitchen garbage. |
| Heartgold | They love to gather in smelly areas where sludge accumulates, making the stench around them worse. |
| Soulsilver | Its body is made of a powerful poison. Touching it accidentally will cause a fever that requires bed rest. |

| OmegaRuby | 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. |
| AlphaSapphire | 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. |
| Sun | The stench it gives off will make your nose scrunch up. Still, there are Muk fans who think that’s a good thing. |
| Moon | After recent environmental improvements, this Pokémon is now hardly seen at all. People speculate that it may go extinct at some point. |
| UltraSun | Their food sources have decreased, and their numbers have declined sharply. Sludge ponds are being built to prevent their extinction. |
| UltraMoon | Because they scatter germs everywhere, they’ve long been targeted for extermination, leading to a steep decline in their population. |
| Scarlet | It’s thickly covered with a filthy, vile sludge. It is so toxic, even its footprints contain poison. |
| Violet | It’s so stinky! Muk’s body contains toxic elements, and any plant will wilt when it passes by. |
