Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 19 (3d8 + 6) piercing damage. If the target is a Medium or smaller creature, it must succeed on a DC 14 Dexterity saving throw or be swallowed by the dunewinder. A swallowed creature is blinded and restrained, it has total cover from attacks and other effects outside the dunewinder, and it takes 7 (2d6) acid damage at the start of each of the dunewinder's turns. If the dunewinder dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 15 feet of movement, exiting prone.
