Carbuncle

As a bonus action, the carbuncle can cause its garnet to glow or not. While glowing, the garnet sheds bright light in a 10-foot radius and dim light for an additional 10 feet.

The carbuncle has advantage on Dexterity (Stealth) checks made to hide in jungle terrain.

The carbuncle makes one bite attack and one claw attack.

Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) piercing damage.

Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) slashing damage.

The carbuncle shoots a 30-foot-long, 5-foot-wide line of scintillating light from the garnet on its forehead. Each creature in that line must make a DC 13 Dexterity saving throw, taking 10 (3d6) radiant damage on a failed save, or half as much damage on a successful one.
