Cursed Puppet

Inconspicuous. While the puppet remains motionless and out of combat, it gains a +5 to Stealth rolls, and is indistinguishable from a normal puppet.

Evasion. When the puppet is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.

Magical Properties. Weapon attacks made by the puppet are considered magical for the purpose of overcoming resistance.

Spellcasting. The Cursed Puppet has innate magic casting abilities. (spell save DC 12 to hit with spell attacks). The Puppet has following spells prepared:
Cantrips (at will): Vicious Mockery, Minor Illusion, True Strike
1st level (4 slots): Hellish Rebuke, Hideous LaughterConcentration

Wild Slashes. The puppet makes 3 attacks on the same target when it makes an attack with the Dagger or Claws.

Dagger.  Melee or Ranged Weapon Attack: +5 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 5 (1d4 + 3) piercing damage.

Claw. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 12 (2d4 + 3) necrotic damage.

Cursed Strings (3/day). The puppet  shoots a web of strings at any number of creatures within a 15 foot radius. Creatures within range must succeed on a Dexterity saving throw (DC 15) or be restrained for the next 5 turns. While a creature is restrained in this way the haunted puppet's movement speed is reduced by 10 feet. The target can attempt a strength saving (DC 15) throw at the end of each of its turns, ending the effect on itself on a success.

Haunting Gaze. The puppet targets one creature it can see within 30 feet of it. If the target can see the puppet, the target must succeed on a DC 12 Constitution saving throw against this magic or take 14 (4d6) psychic  damage and then be paralyzed for 1 turn. 

Scurry. When a creature misses an attack against the haunted puppet, it can move half its movement speed in any direction without provoking attacks of opportunity.
