Apparently it is pale, brown and watery, but it is prized as a gourmet foodstuff. Its description and habitat seem puzzling, as Klatch is largely a region of desert and oasis where bogs would seem to have great rarity value. Perhaps this predicates its worth as an expensive gourmet foodstuff? It graces dinner tables of the rich and famous in Mort.
