Rend (Ex): A girallon that hits with both claw attacks latches onto the opponent's body and tears the flesh. This attack automatically deals an additional 2d4+12 points of damage.

Girallons attack anything that enters their territory, even others of their kind. Their senseless belligerence is the one characteristic that keeps their numbers check. Still, the creatures show some cunning.

A solitary girallon usually conceals itself in the branches. of a tree or under a pile of leaves and brush, with only its nose showing. When it sport or scents prey, it charges to the attack. The girallon picks up prey that is small enough to carry and withdraws, often, vanishing into the trees before the victim's companions can do anything to retaliate. Against larger foes, the girallon seeks to tear a single opponent to bits as quickly as it can.
