Multiattack. The dragon makes two attacks: one with its bite and one with its claws or two with its claws.

Bite. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit:(1d10 + 4) piercing damage.

Claw. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit:(1d6 + 4) slashing damage.

Breath Weapon (Recharge 5–6).

Acid Breath. The dragon exhales acid in an 40-foot line that is 5 feet wide. Each creature in that line must make a DC 14 Dexterity saving throw, taking  (5d8) acid damage on a failed save, or half as much damage on a successful one.

Change Shape (Limited). Once per day, up to 30 minutes. Requires Concentration. The dragon wyrmling can magically polymorph into a small animal (such as a cat or small dog) or a juvenile humanoid, and can revert to its true form. While transformed, it retains its alignment and personality. The transformation ends early if its concentration is broken. The wyrmling cannot duplicate the appearance of a specific individual, and the transformation does not grant new abilities (e.g., the flight of a bird).
