The wumpus, q, is a monster that appears in NetHack.
The wumpus is randomly generated at a relatively rare rate, though not nearly as rare as other monsters.
The Ranger quest locate level will always generate a wumpus on the downstairs.
The wumpus is very slow, but has a strong bite attack and can cling to ceilings, allowing it to generate over and move past moats without drowning or being relocated. Even so, its sluggish movement makes it an easy target for any player with good kiting or ranged attacks at their disposal, and it has no resistances whatsoever to boot.
The Wumpus, by the way, is not bothered by the hazards since
he has sucker feet and is too big for a bat to lift. If you
try to shoot him and miss, there's also a chance that he'll
up and move himself into another cave, though by nature the
Wumpus is a sedentary creature.
