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

A tendriculos that hits with a tendril attack grabs as above. If it gets a hold it picks up the opponent and transfers it to the mouth as a partial action, automatically dealing bite damage as above.

Swallow Whole/Paralysis (Ex): A tendriculos can try to swallow a grabbed opponent of Large or smaller size by making a successful grapple check. Once inside the plant's mass, the opponent must succeed at a Fortitude save (DC 19) or be paralyzed for 3d6 rounds by the tendriculos' digestive juices, taking 2d6 points of acid damage per round. A new save is required each round inside the plant.

A swallowed creature that avoids paralysis can climb out of the mass with a successful grapple check. This returns it to the plant'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 tendriculos' interior (AC 15). Once the creature exits, the plant's amazing regenerative capacity closes the hole; another swallowed opponent must again cut its own way out.

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

Regeneration (Ex): Bludgeoning weapons and acid deal normal damage to a tendriculos. A tendriculos that loses part of its body mass can regrow it in 1d6 minutes. Holding the severed portion against the mass enables it to reattach instantly.

Prowling deep forests or waiting in vegetated areas (looking like nothing more than a small hillock), the tendriculos attacks savagely, showing no fear. It attempts to swallow as much flesh as it can, as quickly as it can.
