Couatl

Melee Weapon Attack: +8 to hit, reach 5 ft., one creature. Hit: 8 (1d6 + 5) piercing damage, and the target must succeed on a DC 13 Constitution saving throw or be poisoned for 24 hours. Until this poison ends, the target is unconscious. Another creature can use an action to shake the target awake.

Melee Weapon Attack: +6 to hit, reach 10 ft., one Medium or smaller creature. Hit: 10 (2d6 + 3) bludgeoning damage, and the target is grappled (escape DC 15). Until this grapple ends, the target is restrained, and the couatl can’t constrict another target.

Strength Saving Throw: DC 15, one Medium or smaller creature the couatl can see within 5 feet. Failure: 8 (1d6 + 5) Bludgeoning damage. The target has the Grappled condition (escape DC 13), and it has the Restrained condition until the grapple ends.

The couatl is immune to scrying and to any effect that would sense its emotions, read its thoughts, or detect its location.

The couatl’s thoughts can’t be read by any means, and other creatures can communicate with it telepathically only if it allows them.
