Improved Grab A t-rex that successfully hits with its bite attack may attempt to start a grapple as a free action without provoking an attack of opportunity.
Natural Armor A t-rex's thick hide gives it +5 natural armor and DR 5.
Swallow Whole A t-rex that begins its turn grappling a target of size large or smaller may swallow that target whole as a standard action by making a successful grapple check. Once the target is swallowed, it is still considered to be grappled, although the t-rex is now free to act normally. The target takes 2d6+18 damage from being swallowed, then automatically takes that damage damage each additional round from muscle constriction, stomach acid, and so forth, and begins to suffocate. Targets with acid resistance or DR vs. bludgeoning do not apply the resistance, but only take half damage. The swallowed creature may attempt to cut their way out with a light slashing or piercing weapon. The Ref defense required to effectively cut through is 12, and the target must do 20 hp to cut through the gullet. This immediately moves the t-rex -2 steps down the condition track. Once the hole is made, any additional creatures still in the gullet may attempt to escape by making Acrobatics checks against DC 16, or by doing 10 hp total. Alternatively, a swallowed target may make a Climb check or Grapple check (whichever is higher) vs. the t-rex's Grapple check to climb back up into the mouth, where it may be bitten or swallowed again. A t-rex can hold 1 large or 2 medium or 4 small creatures in its gullet, and will not swallow another creature whole if it has been cut open.
All that and it only came out to be CL 15. Can you believe it?
