This creature is a very large version of the giant pit viper snake. It has been created by the Immortal Demogorgon to help further her causes.

Gargantua pit vipers are only aggressive if they feel threatened or if directed to attack by Demogorgon. They can be hard to spot despite their size. Their bite is very poisonous.

Improved Grab (Ex): If a Gargantua pit viper hits with its bite attack, it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. If the grapple succeeds, the Gargantua pit viper may attempt to swallow the victim whole in the next round. A Gargantua pit viper may only grab an opponent that is Medium size or smaller.

Poison (Ex): A Gargantua pit viper has a poisonous bite that deals initial and secondary damage of 2d4 Con. The save DC is 19 and Constitution-based.

Swallow Whole (Ex): A Gargantua pit viper can try to swallow a grappled opponent of up to two sizes smaller by making a successful grapple check. The swallowed creature takes 1d8+10 points of bludgeoning damage and 5 points of acid damage per round from the Gargantua pit viper's gizzard. A swallowed creature can cut its way out by using a light slashing or piercing weapon to deal 20 points of damage to the gizzard (AC 14). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out.
A Gargantua pit viper's gizzard can hold 2 medium, 8 small, 32 tiny, 128 diminutive or smaller opponents.

Scent (Ex): This special quality allows a Gargantua pit viper to detect approaching enemies, sniff out hidden foes, and track by sense of smell.

Skills: Gargantua pit vipers have a +4 racial bonus on Hide, Listen, and Spot checks and a +8 racial bonus on Balance and Climb checks. A pit viper can always choose to take 10 on a Climb check, even if rushed or threatened. Snakes use either their Strength modifier or Dexterity modifier for Climb checks, whichever is higher. A pit viper has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.
