Mouth of Madness. The giant is immune to confusion spells and similar magic. On each of its turns, the giant uses all its movement to move toward the nearest creature or whatever else it might perceive as food. Roll a d10 at the start of each of the giant's turns to determine its action for that turn:

1–3. The giant makes three attacks with its claws against one random target within its reach. If no other creatures are within its reach, the giant flies into a rage and gains advantage on all attack rolls until the end of its next turn.

4–5. The giant makes one attack with its claw against every creature within its reach. If no other creatures are within its reach, the giant makes one claw attack against itself.

6–7. The giant makes one attack with its bite against one random target within its reach. If no other creatures are within its reach, its eyes glaze over and it becomes stunned until the start of its next turn.

8–10. The giant makes three attacks against one random target within its reach: one attack with its bite and two with its claws. If no other creatures are within its reach, the giant flies into a rage and gains advantage on all attack rolls until the end of its next turn.

Bite. Melee Weapon Attack:+12 to hit, reach 5 ft., one target. Hit: 24 (3d12 + 5)piercing damage. If the target is a humanoid, it must succeed on a DC 14 Constitution saving throw or be cursed with wereshark lycanthropy. If the target is a Large or smaller creature, it must succeed on a DC 19 Dexterity saving throw or be swallowed by Urom. A swallowed creature is blinded and restrained, it has total cover against attacks and other effects outside of Urom, and it takes 21 (6d6) acid damage at the start of each of Urom's turns, Urom magically regains that same amount of hit points.

If Urom takes 30 damage or more on a single turn from a creature inside it, the giant must succeed on a DC 21 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of Urom. If Urom dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 20 feet of movement, exiting prone.

Claw. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 24 (3d12 + 5) slashing damage.
