Actions

Multi-attack The Wennbar makes two attacks, one slam, and one bite or swallow attack

Bite. Melee Weapon Attack: +10 to hit, reach 30ft., one target. Hit 17 (3d6 + 5) piercing damage. The target then needs to make a dexterity saving throw DC 15 or it becomes grappled

Slam. Melee Weapon Attack: +10 to hit, reach 5ft., one target. Hit 5 (3d6 + 5)

Swallow The Wennbar makes one bite Attack against a Medium or smaller creature it is Grappling. If the Attack hits, the target takes the bite's damage, the target is swallowed, and the grapple ends. While swallowed, the creature is Blinded and Restrained, it has total cover against attacks and other effects outside the tarrasque, and it takes 32 (8d6) acid damage at the start of each of the tarrasque's turns. If the Wennbar takes 30 damage or more on a single turn from a creature inside it, the Wennbar must succeed on a DC 20 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the Wennbar. If the Wennbar dies, a swallowed creature is no longer Restrained by it and can escape from the corpse by using 30 feet of Movement, exiting prone.
