A wumpus can cling to ceilings. It has an animal body. It has no hands. It is an omnivore.

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.
