Throat Spikes (Ex): Like all greater drakes, the trilligard has an inflatable throat bladder; unlike most, trilligards use their bladders defensively. The over-large throat pouch is covered with thousands of needle-sharp spines that normally lie flat against the skin. However the spikes project outward when the pouch is fully inflated. Those attacking a trilligard with natural or light weapons must make a Reflex save (DC 15) to avoid taking 1d6 points of damage from the creature's numerous spines.

Skills*: While its natural scale coloration ranges from green to brown, the trilligard has a chameleon-like ability to alter its scale colors to blend in with its surroundings. This grants the trilligard a +10 racial bonus to Hide skill checks. This bonus is included in the trilligard's Hide skill modifier.
