Sensory Overload. The chiminimera has a bonus to its initiative rolls equal to its Wisdom modifier. In addition, it has advantage on Wisdom (Perception) checks that rely on sight, hearing or smell and disadvantage on saving throws against being frightened by sudden noise or light.
Multiattack. The chiminimera makes two attacks, one with its bite and one with its sting. When it can use its acid breath attack, it can do so instead of its bite.
Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) piercing damage.
Sting. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) piercing damage, and the target must make a DC 12 Constitution saving throw, taking 5 (2d4) poison damage on a failed save, or half as much on a successful one.
Acid Breath (Recharge 6). The snake head exhales acid ion a 10-foot line that is 5 feet wide. Each creature in that line must make a DC 12 Dexterity saving throw, taking 7 (3d4) acid damage on a failed save, or half as much on a successful one.
