Leap (Recharge 5-6)

The bulette leaps up to half its Speed horizontally and half its Speed vertically without provoking opportunity attacks and can land in a space containing one or more creatures. Each creature in its space when it lands makes a DC 15 Dexterity saving throw taking 18 (4d6 + 4) bludgeoning damage and being knocked prone on a failure. On a success the creature takes half damage and is pushed 5 feet to a space of its choice. If that space is occupied the creature is knocked prone.

Burrow

The bulette burrows under the ground without provoking opportunity attacks moves up to its burrow speed and then resurfaces in an unoccupied space. If it is within 5 feet of a creature it then makes a bite attack.

Bite

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