Awakened Ventriloquist Dummy

False Appearance. While the dummy remains motionless, it is indistinguishable from a normal ventriloquist dummy.

Voice Mimicry. The dummy can mimic any voices it has heard. A creature that hears the sounds can tell they are imitations with a successful DC 14 Wisdom (Insight) check.

Multiattack. The dummy makes on attack and then uses its Dominate if it can.

Strike. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) bludgeoning damage.

Topple. Melee Weapon Attack: +4 to hit, reach 5 ft., one target under the effect of another dummy's Lunge. Hit: 4 (1d4 + 2) bludgeoning damage and the target must succeed on a DC 13 Strength saving throw or be knocked prone. If the target fails the saving throw by 5 or more, the target is also restrained (escape DC 13) by the dummy. 

Lunge. Melee Weapon Attack: +4 to hit, reach 5 feet., one small to large target. Hit: 4 (1d4 + 2) bludgeoning damage, and the dummy attaches to the target. If the target is Large, Medium, or Small and the dummy has advantage on the attack roll, it attaches by engulfing the target's head, and the target is also blinded while the dummy is attached in this way.
While attached to the target, the dummy can attack no other creature except the target but has advantage on its attack rolls. The dummy speed also becomes 0, it can't benefit from any bonus to its speed, and it moves with the target.
A creature can detach the dummy by making a successful DC 13 Strength check as an action. On its turn, the dummy can detach itself from the target by using 5 feet of movement.

Ventriloquize (Recharge 5-6). The dummy targets on creature under the effects of its lunge attack. The target must make a DC 9 Wisdom saving throw. On a fail, the creature takes only the actions the dummy chooses, and doesn't do anything that the dummy doesn't allow it to do until the end of the dummy's next turn. During this time the dummy can also cause the creature to use a reaction, but this requires the dummy to use its own reaction as well. Each time the target takes damage, it makes a new Wisdom saving throw against the spell. If the saving throw succeeds, the spell ends. On a success, the target is unaffected.
