Yumyuk Moss is a pinkish-red substance which is highly prized by dwarves. It is very rare and grows in dank caves; when harvested, it is stored in a dusty clay pot. It smells sweet, like berries, and when first tasted, it might be the best thing one has ever experienced ("there's the 'yum'..."), only to then taste "terrible - like there's a hell in [the taster's] mouth and everyone's been damned!" a moment later ("and there's the 'yuck'."). Dwarves actually eat the substance, but they're usually drunk. Forgath found a pot of it in the hut of Young-And-Beautfiul.
