These massive scavengers attempt to consume any organic material they find. Sandworms are feared for swallowing their prey whole: Entire groups of adventurers have vanished down their gullets, one member after the other. A sandworm consumes great quantities of dirt and rock when tunneling. Its gizzard may hold gems and other acid-resistant items. In mineral-rich areas, sandworm castings might contain unrefined ores
Improved Grab (Ex): To use this ability, a purple worm must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can attempt to swallow the foe the following round.
Swallow Whole (Ex): A sandworm can try to swallow a grabbed opponent of a smaller size than itself by making a successful grapple check. Once inside, the opponent takes 2d8+12 points of crushing damage plus 8 points of acid damage per round from the worm’s gizzard. A swallowed creature can cut its way out by using a light slashing or piercing weapon to deal 25 points of damage to the gizzard (AC 17). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out. A Gargantuan worm’s interior can hold 2 Large, 8 Medium, 32 Small, 128 Tiny, or 512 Diminutive or smaller opponents.
Orangespice Creation (Ex): A sandworm produces 1 pound per HD of orangespice per week. It leaves orangespice in its wake as it travels. Patches of orangespice occasionally work their way to the surface where they are easily harvested.
