The mustard jelly, thought to be related to the ochre jelly, however it is far more dangerous, is a large, amorphous ooze. The only clue to its presence is a faint odor (that can be detected at 20 feet) not unlike that of blooming mustard plants. That and its translucent yellowish-brown color give it its name.

   Unlike other oozes, the mustard jelly cannot climb walls or stick to ceilings.

 

COMBAT

A mustard jelly attacks by forming a pseudopod of its acidic substance and striking with it.

   Improved Grab (Ex): To use this ability, the mustard jelly must hit with its slam attack. If it gets a hold, it can constrict.

   Constrict (Ex): A mustard jelly deals automatic slam and acid damage with a successful grapple check.

   Acid (Ex): A mustard jelly secretes a digestive acid that dissolves only flesh and wood. Any melee hit deals acid damage.

   Poisonous Aura (Ex): 10-foot radius, affected as by slow spell as cast by a 12th-level sorcerer, Fortitude negates DC 15. The save must be made each round a creature is within range.

   Split (Ex): Weapon and electricity attacks deal no damage to a mustard jelly. Instead the creature splits into two identical jellies, each with half the original’s hit points (round down). A jelly with only 1 hit point cannot be further split.

   Ooze: Immune to mind-influencing effects, poison, sleep, paralysis, stunning, and polymorphing. Not subject to critical hits.

 

 

The Mustard Jelly first appeared in the 1e MM (Gary Gygax, 1977).
