Chaospout

Charming Exterior. Any creature that attempts to interact with the Chaospout must succeed on a DC 13 Charisma saving throw or be charmed by the Chaospout until the creature finishes a long rest. While charmed, the creature finds it impossible to harm the Chaospout and will feed it. Additionally the creature cannot gain the effects of a long rest unless the Chaospout is within 5 ft of the creature.

Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) piercing damage. 

Interior Probing. The Chaospout whispers into the ear of a sleeping creature. To any creature awake this sounds like squeaks and whimpers, but the sleeping creature hears a familiar voice in its dreams. The sleeping creature must succeed on a DC 17 Charisma check or the Chaospout convinces them that an ally, or allies if the Chaospout feels its victim is strong enough, means them harm. The creature suddenly awakes and attacks their allies. This effect continues until the Chaospout dies, the charmed creature dies, or the charmed creature succeeds on a DC 17 Charisma saving throw which it makes at the end of each of its terms.

Pitiful Squeak. The first time the Chaospout is attacked in combat it yells out, summoning two additional Chaospout. The Chaospout cannot use this reaction unless it is alone in combat and summoned Chaospout cannot use this reaction.
