Mountain Goat

If the goat moves at least 20 feet straight toward a target and then hits it with a ram attack on the same turn, the target takes an extra 3 (1d6) Bludgeoning damage. If the target is a creature, it must succeed on a DC 12 Strength saving throw or be knocked Prone.

The goat has advantage on Strength and Dexterity saving throws made against effects that would knock it Prone.

Melee Weapon Attack +4 to hit, reach 5 ft., one target. 5 (1d6 + 2) Bludgeoning damage.
