Who Is Muk?

New readers often wonder just who this Muk guy is. Here's some edification from the ol' Wikipedia,

Muk, quite frankly, is the personification of sludge and bad hygiene. Muk thrives in toxic waste and garbage. It inhabits any polluted area; including abandoned factories, garbage dumps and sewers.

Muk itself is also a source of pollution. As Muk slides across the ground, it leaves behind a trail of highly poisonous sludge.

No one tampered with that entry either. Ouch.
