Multiattack. The dragon tortoise makes three attacks: one with its bite and two with its claws. It can make one tail attack in place of its two claw attacks.

Bite. Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit:26 (3d12 + 7) piercing damage.

Claw. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit:16 (2d8 + 7) slashing damage.

Tail. Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit:26 (3d12 + 7) bludgeoning damage. If the target is a creature, it must succeed on a DC 20 Strength saving throw or be pushed up to 10 feet away from the dragon tortoise and knocked prone.

Sand Breath (Recharge 5–6). The dragon tortoise exhales abrasive sand in a 60-foot cone. Each creature in that area must make a DC 18 Constitution saving throw, taking 52 (15d6) slashing damage on a failed save, or half as much damage on a successful one.
