Standing Leap. The Vomitting Bug's long jump is up to 50 feet and its high jump is up to 25 feet, with or without a running start. Bonus action 'Pounce' - like dash but jumping and landing.

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 30 (4d12 + 4) piercing damage.

Acid Breath (Recharge 5–6). The Bug exhales poisonous gas in a 15-foot cone. Each creature in that area must make a DC 11 Constitution saving throw, taking 21 (6d6) poison damage on a failed save, or half as much damage on a successful one.

Deadly Leap. If the Vomitting Bug 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 16 Strength or Dexterity saving throw (target's choice) or be knocked prone and take 14 (5d6 + 6) bludgeoning damage plus 14 (5d6 + 6) 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 Vomitting Bug'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 Vomitting Bug's space.
