The dragon can burrow through solid rock at half its burrowing speed and leaves a 10-foot-diameter tunnel in its wake.
The dragon doesn't require air.
The dragon makes one Bite attack and two Claw attacks.
Melee Attack Roll: +7 to hit, reach 10 ft., one target. Hit: 7 (1d6 + 4) piercing damage plus 3 (1d6) cold damage.
Melee Attack Roll: +7 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) slashing damage.
The dragon exhales a blast of frost in a 30-foot cone. Each creature in the cone must make a DC 15 Constitution saving throw. On a failed save, the creature takes 27 (6d8) cold damage, and its speed is halved until the end of its next turn. On a successful save, the creature takes half as much damage, and its speed isn't reduced.
