Constrict (Ex): On a successful grapple check, a tree python deals 1d3+4 points of damage.

Improved Grab (Ex): To use this ability, a tree python must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can constrict.

Chameleon Scales (Ex): Because of its ever-changing scales, a tree python blends in with its surroundings, gaining a +10 circumstance bonus on Hide checks.

Spring (Ex): A tree python can gather its coils and then launch itself in a jump. The Jump DCs for both long jumps and high jumps are halved, and no running start is required. Furthermore, when jumping down, the tree python takes damage as if it had dropped 90 fewer feet than it actually did.

Skills: A snake has a +4 racial bonus on Hide, Listen, and Spot cheeks and a +8 racial bonus on Balance and Climb checks. A snake can always choose to take 10 on a Climb check, even if rushed or threatened. A snake uses either its Strength modifier or its Dexterity modifier for Climb checks, whichever is higher.

A tree python 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.

Tree pythons are intelligent hunters that never forget previous experiences. They are wise enough to drop onto the last creature in a passing group, choose isolated targets, and avoid falling onto glinting metal. Tree pythons usually hunt by night and sleep by day, but they have been known to follow promising prey tirelessly, keeping pace and attacking it later while it slumbers.
