Actions

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 10 (1d12 + 4) piercing damage plus 7 (2d6) poison damage, and the target is grappled (escape DC 15). Until this grapple ends, the target is restrained and the sea serpent cannot grapple another target. While the fanged serpent has a creature grappled in its bite, it cannot bite a different creature, and has advantage on bite attacks against the grappled creature.

Roll. One target that the fanged serpent has grappled takes 21 (6d6) slashing damage as the fanged serpent rolls quickly. After this damage is dealt, the target is no longer grappled.
