Muk, the Sludge Pokémon. A horribly toxic liquid seeps out of its body.
– Dawn’s Pokedex
Muk is one of those Pokemon that makes me think “What the heck are they thinking?!” It’s a pile of toxic goo… Though its sprites have its arm going up, kinda like a gangsta, haha.
Stat-wise, it’s got decent defense and attack, but I don’t think it’s often used competitively.
