Multiattack. The goose makes one Beak attack and two Wing attacks.

Beak. Melee Weapon Attack: +4 to hit, reach 10 ft., one target. Hit: 9 (2d6 + 2) bludgeoning damage.

Wing. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 (1d10 + 2) bludgeoning damage, and the target must succeed on a DC 12 Strength saving throw or have the prone condition.

Thunderous Honk (Recharge 5–6). The goose honks with ear-splitting volume. Each other creature within 30 feet of the goose must make a DC 12 Constitution saving throw. On a failed save, a creature takes 16 (3d10) thunder damage and has the deafened condition until the start of the goose's next turn. On a successful save, a creature takes half as much damage only. The honk can be heard within 300 feet.
