Demogoose

When the demogoose flies, each creature within 10 feet of its starting and landing point makes a DC 12 Constitution saving throw. On a failed save, a creature becomes poisoned until the end of its next turn.

The demogoose ignores difficult terrain, and magical effects can't reduce its speed or cause it to be restrained. It can spend 5 feet of movement to escape from nonmagical restraints or being grappled.

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 3) piercing damage and 5 (1d10) poison damage and the target makes a DC 13 Constitution saving throw. On a failed save, it has disadvantage on its next ability check or attack roll before 1 minute has passed because of the pain of the bite.

The demogoose honks into the air to put terror in the hearts of its enemies. Each creature of the demogoose's choice that is within 60 feet of the demogoose and can hear it must succeed on a DC 13 Wisdom saving throw or become frightened for 1 minute.

The demogoose has advantage on attack rolls against frightened creatures. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the demogoose's Frightful Presence for the next 24 hours.

The demogoose breathes fire in a 40-foot line in front of it. Any creature in the area makes a DC 12 Dexterity saving throw, taking 14 (4d6) fire damage on a failed save, or half as much damage on a success.
