Special Abilities
Grab (Ex) An animate entrail is treated as Medium size for grapple checks.
Infestation (Ex) The bite of an animate entrail injects the victim with its larva. A bitten opponent must succeed on a DC 14 Fortitude save or become infested. The save DC is Constitution-based and includes a +4 racial bonus. The larva work their way to the bowels dealing 1 Constitution damage as they move. The larva fight among themselves until only one remains. It slowly consumes the intestines of the host over the next 3d4 days, replacing the organ with itself; a animate entrail  draws nourishment from food consumed by the host, and the host must consume twice times as much food and water or suffer the effects of starvation. The larva can be killed with a remove disease spell but once it is fully grown it must be cut out, which deals 4d6 points of damage to the victim. Repairing the damage to the intestines requires a DC 25 Heal check or a regenerate spell or the victim cannot gain nourishment from food.
Strangle (Ex) Animate entrails wrap around the necks of their victims. A creature that starts its turn grappled by an animate entrail cannot speak or cast spells with verbal components

living intestines

Also known as “living intestines” these horrible parasites are distantly related to tapeworms. Animate entrails live in the digestive tracts of unfortunate victims, replacing their organs and making it difficult to remove the parasite without killing the host. Fortunately, animate entrails are mostly harmless to their hosts so long as they have adequate nourishment and are not injured.

Animate entrail are asexual and start producing larva when they reach adulthood. A living intestine cannot survive long outside of a host body, drying out and starving to death. When the host dies the animate entrail readies itself to emerge and infest a nearby creature with its young. If there are living creatures nearby it immediately forces it’s way out of the corpse. If there are no creatures nearby the animate entrail begins to hibernate, waiting until potential hosts arrive. A living intestine will also emerge from a living host if it is being starved, bursting forth to try and procreate before perishing.
