Swallow from Below. While the Urdracturus is burrowed underground it can attempt to grapple a creature above it. The creature of large or smaller size must succeed on a DC 17 Dexterity saving throw or be swallowed (escape DC 17) and pulled 10 feet underground, if the creature is the same size as the Urdacturus it will be only grappled and will remain grappled in place, taking 21 (6d6) bludgeoning damage. While grappled this way, the creature is restrained and blinded. The creature takes an additional 17 (5d6) acid damage at the start of each of its turns. The swallowed creature is blinded, has total cover against attacks and other effects outside the Urdracturus, and while inside the mouth of the Udracturus is free to attack, but not move. If the Urdracturus takes 30 damage or more on a single turn from a creature inside it, the Urdracturus must succeed on a DC 20 Constitution saving throw at the end of that turn or spit out the swallowed creature, which falls prone in a space within 15 feet of the Urdracturus.

The Urdracturus slams into the ground and erupts from below in a violent burst of earth and stone. The Urdracturus burrows up to 30 feet and emerges, causing the ground within a 20-foot radius of its eruption point to quake. Each creature in that area must make a DC 17 Dexterity saving throw, taking 48 (8d6 + 20) bludgeoning damage on a failed save and falls prone, or half as much damage on a successful one and isn't prone. The area becomes difficult terrain until cleared.
