Khodumodumo

While the khodumodumo remains motionless, it is indistinguishable from an ordinary earthen hill.

The khodumodumo can have up to six impaling tongues at a time. Each tongue can be attacked (AC 20; 15 hp; immunity to poison and psychic damage). Destroying a tongue deals no damage to the khodumodumo. A tongue can also be broken if a creature takes an action and succeeds on a DC 18 Strength check against it. Destroyed tongues regrow by the time the khodumodumo finishes a long rest.

Melee Weapon Attack: +11 to hit, reach 10 ft., one creature. Hit: 33 (6d8 + 6) piercing damage. If the target is a Large or smaller creature grappled by the khodumodumo, that creature 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 khodumodumo, and it takes 21 (6d6) acid damage at the start of each of the khodumodumo's turns.

If the khodumodumo takes 30 damage or more on a single turn from a creature inside it, the khodumodumo 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 khodumodumo. If the khodumodumo dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 15 feet of movement, exiting prone.

The khodumodumo makes three attacks with its tongues, uses Reel, and makes one attack with its bite.

The khodumodumo pulls each creature grappled by it up to 25 feet straight toward it.

Melee Weapon Attack: +11 to hit, reach 50 ft., one creature. Hit: The target is grappled (escape DC 18). Until this grapple ends, the target is restrained, and the khodumodumo can't use the same tongue on another target. In addition, at the start of each of the target's turns, the target takes 8 (1d4 + 6) piercing damage.
