Pombero

Beast's Voice. The pombero can magically speak with any beast and can perfectly mimic beast sounds.

Twisted Limbs. The pombero can twist and squeeze itself through a space small enough for a Tiny bird to pass through as if it were difficult terrain.

Sneak Attack (1/turn). The pombero does an extra 7 (2d6) damage with a weapon attack when it has advantage on the attack roll, or when the target is within 5 feet of an ally of the pombero that isn't incapacitated and the pombero doesn't have disadvantage on the roll.

Soft Step. The pombero has advantage on Dexterity (Stealth) checks in forest terrain.

Multiattack. The pombero uses Charming Touch if able, and makes two fist attacks.

Fist. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) bludgeoning damage and the target is grappled (escape DC 13).

Charming Touch (recharge 5-6). The pombero chooses a creature it can see within 5 feet. The creature must make a successful DC 12 Wisdom saving throw or be charmed for 10 minutes. The effect ends if the charmed creature takes damage. The pombero can have only one creature at a time charmed with this ability. If it charms a new creature, the previous charm effect ends immediately.

Invisibility. The pombero becomes invisible until it chooses to end the effect as a bonus action, or when it attacks.
