The massive pool of inky goo regards you carefully, reacting to your movements.
Acid (Ex): Any melee hit or constrict attack deals 3d6 points of acid damage. Armor and clothing is dissolved (DC 29 Reflex save negates). Wooden or metal weapons striking the elder sentry pudding are dissolved (Reflex DC 29 negates).
Constrict (Ex): An elder sentry pudding deals automatic slam and acid damage on a successful grapple check. The opponent's armor and clothing take a -4 penalty on Reflex saves against the acid.
Split (Ex): Piercing and slashing weapons deal no damage to an elder sentry pudding. Instead, the creature splits into two identical puddings, each with half the original's current hit points (round down). A pudding with 10 or fewer hit points cannot be further split, and the creature dies if reduced to 0 hit points.
