Your hooves are natural melee weapons, which you can use to make unarmed strikes. If you hit with them, you deal bludgeoning damage equal to 1d4 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.

Immediately after you hit a creature with a melee attack as a part of the Attack action on your turn, you can use a bonus action to attempt to shove that target with your horns. The target must be within 5 feet of you and no more than one size larger than you. Unless it succeeds on a Strength saving throw against a DC equal to 8 + your proficiency bonus + your Strength modifier, you push it up to 10 feet away from you.
