Stench kow

From Ardrana

Stench kine resemble huge, misshapen bison. Bulls have large humps over the shoulders, and cows have smaller ones. Horns are long and downward curving. Heads are huge with pugged features, large round eyes, and lolling tongues. Coloration is dull orange with greenish, matted manes.

Stench kine are the cattle of the Nine Hells. They roam the reeking plains, fiery fields, and even the wintry wastes of the lower hells. Some are found as far as the planes of Acheron, Gehenna, and even The Gray Waste. Much as do common herd animals, these odorous beasts form great herds, grazing on the noxious and poisonous growths of the vile terrain.

Note: Stench kine originally appeared in this form in the 2nd Edition Monstrous Manual for the AD&D game from TSR, with additional information from the 1st Edition Monster Manual II. Their use here is for the purposes of providing context for the campaign only.
