Oozes attack any creatures they encounter.

Ochre jellies attempt to envelop and squeeze their prey.

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

Acid (Ex): An ochre jelly secretes a digestive acid that dissolves only flesh. Any melee hit deals acid damage.

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

Split (Ex): Weapons and electricity attacks deal no damage to an ochre 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.

Blindsight (Ex): An ooze's entire body is a primitive sense organ that can ascertain prey by scent and vibration within 60 feet.

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