If the target is a Large or smaller creature grappled by Audrey II, that creature is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside Audrey II and it takes 42 (12d6) acid damage at the start of each of Audrey II's turns. If Audrey II takes 50 damage or more on a single turn from a creature inside it, Audrey II must succeed on a DC 25 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of Audrey II. If Audrey II dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 15 feet of movement, exiting prone.
