Dire Crocodile

• Melee (Natural) - 1 x bite +18 (3d6+13/19-20 plus grab). Reach: 15 ft. Grab - Each time this attack is successful, the Dire Crocodile can make a grapple check as a free action to see if it holds his opponent. If successful, the opponent is grappled. Grabbing does not provoke an attack of opportunity Death Roll - After grabbing a target, creatures with Death Roll can use a standard action to roll, knocking the target prone and inflicting bite damage automatically.
• Melee (Natural) - 1 x tail slap +18 (4d8+6). Reach: 15 ft.

Swallow Whole (ex) - When a Dire Crocodile has an opponent grappled at the beginning of its turn (no larger than one size smaller), it can attempt a grapple check to swallow him. Swallowed foes take double damage (half from the bite and half from constriction). Standard damage (bludgeoning) recurs automatically each round. Swallowed creatures are considered grappled (the creature is not). They can escape by climbing out of the creature's gullet (successful grapple check), or by cutting their way out with a L or VL weapon. If you cut your way out, the Dire Crocodile is unable to swallow another creature whole against until the wound heals.
