Vestigial Wings. The zergling's long jump is up to 30 feet and its high jump is up to 15 feet, with or without a running start.

Multiattack. The zergling makes 2 claw attacks.

Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 12 (2d8 + 3) piercing damage. Graze: This attack does 3 damage on a miss.

Deadly Leap. If the zergling jumps at least 15 feet as part of its movement, it can then use this action to land on its feet in a space that contains one or more other creatures. Each of those creatures must succeed on a DC 15 Strength or Dexterity saving throw (target's choice) or be knocked prone and take 17 (4d6 +3) bludgeoning damage plus 17 (4d6 + 3) slashing damage. On a successful save, the creature takes only half the damage, isn't knocked prone, and is pushed 5 feet out of the zergling's space into an unoccupied space of the creature's choice. If no unoccupied space is within range, the creature instead falls prone in the zergling's space.
