The City of Doom is a horrible underground city protected by Grotesquely Grim Bunny from the even more horrible Creepy Weasel Monkey Mole, who lives in a warren beneath a junkyard known as the under-underground. The main appearance of the city is a ruined castle and rocky cliffs. All residents of the city are dark and grim, even the good guys. The main gate has a welcome mat, which is actually a springboard to launch victims directly to the heart of the city.
