Improved Grab (Ex): To use this ability, a killer frog must hit with its bite or tongue 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 attempt to swallow the foe in the following round.

Swallow Whole (Ex): A killer frog can try to swallow a grabbed opponent of up to one size smaller by making a successful grapple check. Once inside, the opponent takes 1d6+3 points of bludgeoning damage plus 1d4 points of acid damage per round from the frog's digestive juices. A swallowed creature can cut its way out using a light slashing or piercing weapon by dealing 5 points of damage to the frog's digestive tract (AC 11). Once a creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out.

A Medium killer frog's gut can hold 1 Small, 2 Tiny, 4 Diminutive, or 8 Fine or smaller opponents.

Tongue (Ex): As a standard action, a killer frog may attack a foe up to 15 feet away with its tongue. If it hits, it deals no damage but immediately makes a grapple check (see Improved Grab above). A killer frog is not considered to be grappling a foe if it uses its tongue to grapple. Once it grapples a foe, the frog can drag him into its square if the creature isn't too heavy (a standard killer frog can pull 230 pounds in this manner) whereupon it can immediately make a free bite attack against the foe, gaining a +2 circumstance bonus on its attack roll.

A killer frog's tongue has AC 13, and can be severed if it takes 5 points of slashing damage. The tongue regrows in one day.

Hold Breath (Ex): A killer frog can hold its breath for a number of rounds equal to four times its Constitution score before it risks drowning (see Drowning).

Skills: A killer frog gains a +8 racial bonus on all Hide and Jump checks. It also 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.

A killer frog typically opens combat by using its tongue to attempt to grapple any Small or smaller enemies. It has little fear and won't hesitate to close to melee with anything that looks remotely edible.
