Sludge Pokémon
Muk is a Poison-type Pokémon, No. 089 in the National Pokédex, introduced in Generation 1 (Kanto region).
« Smells so awful, it can cause fainting. Through degeneration of its nose, it lost its sense of smell. »
Muk is a large, sticky mass of purple sludge, with small eyes and three-fingered arms. In Alola, bright stripes and white poison crystals cover its body.
Its toxins leave land barren for three years. It eats almost any waste. It evolves from Grimer; in Alola, over a hundred poisons power it.
Ash caught the Muk leading Grimer at the Gringey City plant and sent it to Professor Oak, whom it often smothers with affection.
Muk twists the word muck, meaning mud. It suggests living sludge born from toxic waste, and Dorotabō, a three-fingered yōkai of neglected mud.
