Standing Leap: The Bulbaby's long jump is up to 20 ft. and its high jump is up to 10 ft., with or without a running start.
Bite: Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 4 piercing damage. Deadly Leap: If the bulette jumps at least 10 ft. 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 10 Strength or Dexterity saving throw (target's choice) or be knocked prone. On a successful save, the creature takes only half the damage, isn't knocked prone, and is pushed 5 ft. out of the bulbaby'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 bulbaby's space.
A baby bulette.
