Acid (Ex): A white pudding secretes a digestive acid that dissolves organic material quickly, but does not affect stone or metal. Any melee hit or constrict attack deals acid damage, and the opponent's armor (if not metal) and clothing dissolves and become immediately useless unless it succeeds on a DC 19 Reflex saving throw. A wooden weapon that strikes a white pudding also dissolves immediately unless it succeeds on a DC 19 Reflex save. The save DCs are Constitution-based. The pudding's acidic touch deals 19 points of damage per round to wooden, leather, or other organic objects, but the ooze must remain in contact with the object for 1 full round to deal this damage.

Constrict (Ex): A white pudding deals automatic slam and acid damage with a successful grapple check. The opponent's clothing and armor take a -4 penalty on Reflex saves against the acid.

Improved Grab (Ex): To use this ability, a pudding must hit with its slam attack. It can then attempt to start a grapple as a free action without provoking attacks of opportunity. If it wins the grapple check, it establishes a hold and can constrict its prey.

Split (Ex): Slashing and piercing weapons deal no damage to a white pudding. Instead the creature splits into two identical puddings, each with half the original pudding's hit points (round down). A pudding with 10 hit points or less cannot be further split and dies if reduced to 0 hit points.

Skills: White puddings are difficult to spot against snow and ice. They gain a +16 racial bonus on Hide checks in snowy or icy environments.

White puddings attack by grabbing and squeezing their prey. They attack the closest prey, and can be baited into pursuing whatever target offers itself as closest from round to round.
