Мук (Alola)

Red +2: 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 gath­ er in smelly areas where sludge ac­ cumulates, making the stench around them worse.

Silver: Its body is made of a powerful poi­ son. 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.

Emerald: It prefers warm and humid habitats. In the summertime, the toxic substances in its body intensify, making MUK reek like putrid kitchen garbage.

FireRed: It is usually undetectable because it blends in with the ground. Touching it can cause terrible poisoning.

Diamond +5: A toxic fluid seeps from its body. The fluid instantly kills plants and trees on contact.
