Monstrous Flytraps have the following traits:

Plant: Monstrous flytraps have the traits and immunities common to plants.

Improved Grab (Ex):: To use this ability, a monstrous flytrap must hit with its bite attack. If it gets a hold, it can attempt to swallow its opponent (see below), provided its opponent is at least two size categories smaller than it. See Improved Grab.

Swallow Whole (Ex): A monstrous flytrap can swallow a grabbed opponent two size categories smaller than it by making a successful grapple check. The swallowed creature can attack the flytrap from inside its mouth using claws or a Small or Tiny slashing weapon. The flytrap does not release its opponent until it is slain or its swallowed prey is completely drained of blood (that is, dead). A monstrous flytrap\'s mouth can swallow only one opponent at a time and cannot attack while it drains a creature\'s blood.

Blood Drain (Ex): A creature swallowed by a monstrous flytrap takes 1d6+13 points of damage every round due to blood loss. For every 3 hit points it drains, the monstrous flytrap heals 1 hit point of damage. After draining its swallowed prey to death, it expectorates the lifeless husk and seeks out its next meal.

Automatic Language: Monstrous flytraps raised from seedlings can be taught to speak (but neither read nor write) one language.
