Carnivorous Plant

Unmovable Roots. The Carnivorous Plant Cannot be moved by any means.

Bite. Melee Weapon Attack: +8 to hit, reach 15 ft., 1 target. Hit: 11 (3d6) piercing damage. If the target is a creature, it is grappled (escape DC 15). Until the grapple ends, the target is restrained, and the Carnivorous Plant can't bite another target.

Swallow. The Carnivorous Plant makes one bite attack against a Medius or smaller creature it is grappling. If the attack hits, the target takes the bite's damage, and the target is swallowed, and the and the grapple ends. While swallowed, the target is blinded and restrained, it has total cover against attacks and other effects outside the Carnivorous Plant, and it takes 21 (6d6) acid damage at the start of each of the Carnivorous Plant's turn. If the Carnivorous Plant takes 20 damage or more from a creature inside it, the baby must make a DC 15 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 5 feet of the Carnivorous Plant. If the Carnivorous Plant dies, a swallowed creature is no longer restrained by it and can escape the corpse by using 15 feet of movement, exiting prone.

Retract and Defend. The Carnivorous Plant retracts and tenses itself, causing it to gain +3 to it's armour class until the start of it's next turn, but gain disadvantage on Dexterity saving throws.
