Otto The Otyugh
Actually, an otyugh is not technically an 'animal', it's a monster. Usually dwells in sewers, eats garbage and waste, etc. Here's a pic.
Oops, sorry, that's David Hasselhoff. Here's the otyugh.
See? Not an animal.
On the other hand, this Otyugh talks just fine. It kind of glares at you and says:
"
Leave me alone. Don't make me eat this key."
He seems a bit unreasonable about it, huh? On closer inspection, you can see he's wearing a service uniform with the nametag "Otto".
...
Teapot taken Marivhon. It kind of buzzes in your hand.
A quick pass reveals that the otyugh, slimebeasts, and ghouls probably ate most everything else of interest, but you do find a couple bottles of old wine stashed aside.
Tut, gimme Scrounge again, for extra valuables.
Tut, you've raised some good questions. Nothing as of yet seems to indicate what exactly happened here, and it's unlikely some slime beasts were just hanging out all the time in Greyhelm's kitchen. Something seems to have gone horribly, horribly wrong...
