Improved Grab (Ex): To use this ability, the purple worm must hit with its bite attack If it gets a hold, it automatically deals bite damage and can attempt to swallow the foe.

Swallow Whole (Ex): A purple worm can try to swallow a grabbed opponent of Large or smaller size by making a successful grapple check. Once inside, the opponent takes 2d8+12 points crushing damage plus 1d8 points of acid damage per round from the worm's gizzard. A swallowed creature can climb out of the gizzard with a successful grapple check. This returns it to the worm's maw, where another successful grapple check is needed to get free. A swallowed creature can also cut its way out by using claws or a Small or Tiny slashing weapon to deal 25 points of damage to the gizzard (AC 20). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out.

The worm's interior can hold two Large, four Small, eight Tiny, sixteen Diminutive, or thirty-two Fine or smaller opponents.

Poison (Ex): Sting, Fortitude save (DC 24; initial damage 1d6 temporary Strength, secondary damage 2d6 temporary Strength.

Tremorsense (Ex): A purple worm can automatically sense the location of anything within 60 feet that is in contact with the ground.

In battle, a purple worm forms into a coil 15 feet across, biting and stinging anything within reach.
