True. In fact, Ochre Jelly is known to fetch such a good price at market that adventurers have been known to leave behind gold, jewels and mithril chain shirts just to have a quantity to sell. Of course, it has to be processed by an alchemist first to remove its unfortunate caustic side effects. In its natural form, it makes for a very unpleasant depilatory agent...

I hear that the Ochre Jelly is particularly prized as a hair product...and as a result has been hunted to near extinction in this grim, gritty,fashionable world.
