Multiattack. The ventrunculus makes two bite attacks.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) piercing damage, and the target is grappled (escape DC 13) if it is a Huge or smaller creature.

Swallow. The ventrunculus makes a bite attack against creature it is grappling. If the attack hits, the target is swallowed, and the grapple ends. The swallowed creature is blinded and restrained, and it has total cover against attacks and other effects outside the ventrunculus. At the start of each of the ventrunculus's turns, each swallowed creature must succeed on a DC 13 Wisdom saving throw or fall unconcious. While unconscious, the creature doesn't need to breathe, eat, or drink, and it doesn’t age. Divination magic can’t locate or perceive the target.    While the ventrunculus isn't incapacitated, it can regurgitate swallowed creatures at any time (no action required) into spaces within 5 feet of it. The creatures exit prone. If the ventrunculus dies, it likewise regurgitates swallowed creatures. Unconscious creatures regain consciousness when regurgitated.
