- Bite. Melee Attack Roll: +14, reach 10 ft.

Hit: 16 (2d6 + 9) Piercing damage plus 35 (10d6) Poison damage.
Bonus Actions
- Swallow. Strength Saving Throw: DC 19, one Large or smaller creature Grappled by the worm.
Failure: The target is swallowed. The Grappled condition ends. A swallowed creature is Blinded and Restrained, has Total Cover against effects outside the worm, and takes 17 (5d6) Acid damage at the start of each of the worm’s turns.
If the worm takes 30+ damage on a single turn from a creature inside it, it must succeed on a DC 21 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, who fall Prone in a space within 5 feet of the worm.
If the worm dies, any swallowed creature is no longer Restrained and can escape the corpse using 20 feet of movement, exiting Prone.
