Creatures have "ablutions". Nysander told me that when you eat, it has to come out and that it smells. That's what we found in those toilets.
Feldon added that what comes out is not for cooking.
Nysander said something about bowels. Need to take some time to look at the insides of creatures.
Thank goodness Sparko and Nysander took out that wizard, now I can take a look at these bowels.
