Ormid and the gang are about to enter a daemonic dimension to try and hunt down the daemon that stole both the Artificer's soul, and that of NPC Ser Quercus. Just in case, I have statted up one of the "normal" animals from that realm - a beast found in the original AD&D Monster Manual II - The Stench Kow (sic).
So yeah, it's a smelly Hell Cow.
"I said Moo."
Oddly enough, I didn't find any art for these things, other than a copy of the original stats from AD&D.
