Chief Shmug (King of the Hill Giants)

Multiattack. The giant makes two attacks: one with its big stick and one with its bite. 

Big Stick. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: (3d12 + 5) bludgeoning damage.

Rock. Ranged Weapon Attack: +8 to hit, range 60/240 ft., one target. Hit: (5d10 + 5) bludgeoning damage. 

Bite. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: (3d10 + 5) piercing damage. If the target is a creature, it is grappled (escape DC 17). Until this grapple ends, the target is restrained, and Chief Shmug can't bite another target. 

Swallow. Chief Shmug makes one bite attack against a Medium or smaller creature it is grappling. If the attack hits, that creature takes the bite's damage and is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside Chief Shmug, and it takes 21 (6d6) acid damage at the start of each of the Chief Shumg's turns.

If Chief Shmug takes 35 damage or more on a single turn from a creature inside it, Chief Shmug must succeed on a DC 15 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of Chief Shmug. If Chief Shmug dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 16 feet of movement, exiting prone.
