Adult Lesser Camazotzling

Echolocation. The camazotzling can't use its blindsight while deafened.

Flyby. The pteranodon doesn’t provoke an opportunity attack when it flies out of an enemy’s reach.

Keen Hearing. The camazotzling has advantage on Wisdom (perception) checks that rely on hearing.

Pack Tactics. The camazotzling has advantage on an attack roll against a creature if at least one of the camazotzling's allies is within 5 feet of the creature and the ally isn’t incapacitated.

Sunlight Sensitivity. While in sunlight, the camazotzling has disadvantage on attack rolls, as well as on Wisdom (perception) checks that rely on sight.

Multiattack. The camazotzling makes two melee attacks: one with its bite and one with its claws .

Bite. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 16 (3d8 + 3) piercing damage and 5 (2d4) thunder damage.

Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: (2d6 + 3) slashing damage, and the target is grappled if the camazotzling is flying (escape DC 14). If the camazotzling is flying 15 foot or more above the ground, it can use its bonus action to drop the creature it is grappling.

Piercing Shriek (Recharge 6). The camazotzling emits a earpiercing schriek, damageing creatures and objects within a 30 foot cone. Each enemy creature within the 30 foot cone must make a DC 15 Constitution saving throw, taking 34 (7d8) thunder damage and becomes deafened on a failed save, or only taking half as much damage on a succesful one. Constructs and objects made of stone take double damage. 

Call Aid (Recharge 4-6). The camazotzling can summon 1d4 swarms of bats to its aid. The summoned creature appears within 20 feet of the camazotzling and acts as an ally to the camazotzling. It remains for 1 minute, before flying away. If the camazotzling dies, the swarms of bats fly away after the end of their turn.
