Ngobou

Trampling Charge. If the ngobou moves at least 20 feet straight toward a creature and then hits it with a gore attack on the same turn, that target must succeed on a DC 13 Strength saving throw or be knocked prone. If the target is prone, the ngobou can make one stomp attack against it as a bonus action.

Stomp. Melee Weapon Attack: +8 to hit, reach 5 ft., one prone creature. Hit: 18 (3d8 + 5) bludgeoning damage.
