Pungeon Quest: A Pun-Packed Land of Eem Adventure

From publisher blurb: Pungeon Quest is a system-neutral, one-shot adventure designed to be used with any roleplaying game, and dropped into any campaign. Pit your adventuring party against the dastardly Punderlord, a madcap master of puns who delights in cruel and unusual punishment! Encounter the likes of the fowl poltergeese, the deathly hilarious cackletrice, the foppish wearwolf who's late for a costume party, or the poor bastard sword who's just looking for his father.
