Bite

Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 18 (4d6 + 4) piercing damage plus 7 (2d6) acid damage.

Bile Spray (Recharge 5-6)

The citrullus exhales pink bile in a 30-foot cone. Each creature in that area must make a DC 13 Dexterity saving throw. On a failure, the creature takes 14 (4d6) acid damage and is restrained by the sticky seed-filled juice for 1 minute. On a success, the creature takes half the damage and isn't restrained. A creature, including the restrained creature, can take its action to free the restrained creature by succeeding on a DC 13 Strength check.
