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.
