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 damage. If the target is a creature, it must succeed on a saving throw or be knocked prone.

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