If the target is knocked prone, the pachyrhino can make either a stomp or ram attack as a bonus action.
Multiattack. The Pachyrhino makes two attacks: one with its stomp and one with its tail.
Stomp. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: (4d8 + 9) bludgeoning damage. If target is a creature, it must succeed on a DC 16 Strength saving throw or be knocked prone. If the creature is already prone any hit with this attack counts as a critical hit.
