Keen Smell. The crocotta has advantage on Wisdom (Perception) checks that rely on smell.
Gibbering. The crocotta tries to confuse it's prey while it can see any creature and isn't incapacitated. Each creature that starts its turn within 20 feet of the crocotta and can hear the gibbering must succeed on a DC 10 Wisdom saving throw. On a failure, the creature can't take reactions until the start of its next turn and rolls a d8 to determine what it does during its turn. On a 1 to 4, the creature does nothing. On a 5 or 6, the creature takes no action or bonus action and uses all its movement to move in a randomly determined direction. On a 7 or 8, the creature makes a melee attack against a randomly determined creature within its reach or does nothing if it can't make such an attack.
Horrifying Wail. Each creature within 60 feet of the crocotta that can see it must succeed on a DC 13 Wisdom saving throw or be frightened for 1 minute. A frightened target can repeat the saving throw at the end of each of its turns, with disadvantage if the crocotta is within line of sight, ending the effect on itself on a success. If a target’s saving throw is successful or the effect ends for it, the target is immune to the crocotta's Horrifying Wail for the next 24 hours.
Multiattack. The crocotta makes two attacks.
Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 6) piercing damage.
Claws. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 6) slashing damage.
