If the jung-mule can move at least 15 feet towards a target and then makes a successful attack with its slam, it gets to trample the target. The target must make a Dexterity save (DC 14). On a failed save, the target is forced prone and takes an additional 11 (2d10) bludgeoning damage from the creature's feet stomping it. On a successful save, the target takes half damage and is not forced prone.
