Keen Sight. The goose has advantage on Wisdom (Perception) checks that rely on sight.
Life of Crime. The goose has advantage on Dexterity (Sleight of Hand) and (Stealth) checks.
Dexterous Beak. The goose, unlike other beasts, has the ability to pick up and use simple melee weapons with its beak. The weapon has to be no larger than the goose (or no larger than 2ft, DM's choice) to be used. If the goose attempts to use a larger weapon (such as a polearm) the attack roll is made at disadvantage. Any item the goose has picked up can be dropped as an item interaction.
Crafty Strike. As an action, the goose may use a weapon it has picked up using Dexterous Beak to make a melee weapon attack. The damage type of the weapon the goose is wielding determines which form of Crafty Strike it can use.
Swooping Attack. The goose, being an aggressive bird, can swoop at enemies to attack them. While flying, the goose can roll to attack an enemy no further than 120 ft below it. If the enemy is attacked from behind, or unexpectedly by any other means (DM's discretion), the attack roll is made at advantage.
Talons. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) slashing damage.

Swooping Attack. Melee Weapon Attack: +4 to hit, reach 120 ft., one target. Hit: 4 (1d4 + 2) slashing damage.
Honk. As a reaction upon being attacked, the goose can let out a loud and obnoxious honk. All enemies within 30 feet of the goose must make a wisdom saving throw (DC 15) or be stunned until the goose's next turn.
