CLASS: UNKNOWN

   A nonliving, nonsentient structure that grew from a meteorite, this inanimate "monster" forever obeys the whims of the first sentient being it comes into contact with. Its hollow, rocky shell conceals a large mass of red jelly that behaves remarkably like a living creature, engulfing and dissolving any organic substance within reach. This protoplasmic blob can move freely up to a mile from its shell, but will crystallize and disintegrate if forced any farther.

  The Grenzo's jelly is highly susceptible to freezing, and recoils from sources of extreme cold. A faint throbbing sound can be heard from its shell.
