Melee Weapon Attack : +10 to hit, reach 5 ft., one target.  Hit : 4d10+7 piercing damage.

Melee Weapon Attack : special, reach 0 ft., one Large or smaller creature hit by the mosasaur\xe2\x80\x99s bite. The target must make a  Str  save (DC 18) or be swallowed by the mosasaur.

If the mosasaur dies, a swallowed creature can escape by using an action to crawl 10 feet back up its throat. \n'b'\n'b' ABOUT \n'b' Inland seas are home to a variety of large, hungry marine predators, but none are feared as much as the terrible mosasaur. A throwback to a far-distant past when giant reptiles roamed all the oceans of the world, the mosasaur is thankfully rare in the present age. They have been known to sink galleys by ramming them beneath the waterline, then gorge themselves on a dozen or more of the surviving sailors as they struggle in the water. Mosasaurs have also been known to crawl ashore and attack coastal villages, although they are slow and clumsy on land. \n'b' Stocky and powerfully built, this great cat\xe2\x80\x99s most salient feature is a pair of foot-long fangs jutting down from its upper jaw.'
