Kongamato

Breaker of Boats. The kongamato deals double damage to objects and structures made of wood or lighter materials.

Carry Off. The kongamato can fly at half its flying speed when dragging two creatures it has grappled or at its full flying speed if dragging only one creature it has grappled.

Flyby. The kongamato doesn't provoke opportunity attacks when it flies out of an enemy's reach.

Multiattack. The kongamato makes one Beak attack and two Claw attacks.

Beak. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 15 (2d10 + 4) piercing damage.

Claw. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) slashing damage, and the target is grappled (escape DC 15) if it is a Medium or smaller creature. The kongamato has two claws, each of which can grapple only one target.

Terrifying Screech (Recharge 5-6). The kongamato releases a screech in a 30-foot cone. Each creature in the area must make a DC 15 Constitution saving throw. On a failure, a creature takes 28 (8d6) thunder damage and is frightened until the end of its next turn. On a success, a creature takes half the damage and isn't frightened.
