Charge. If the carnotaurus moves at least 20 feet straight toward a target and then hits it with a headbutt attack on the same turn, the target takes an extra 4 (1d8) bludgeoning damage. The carnotaurus can then make a bite attack against it as a bonus action.   Size Advantage. The carnotaurus has advantage on attack rolls with its bite against creatures two size categories smaller than itself.   Sprinter. The carnotaurus can dash as a bonus action as long as it only moves in a straight line on its turn.
