Ahuizotl (5e Creature)
From D&D Wiki
Medium monstrosity, neutral evil
Deceitful Mimicry. The ahuizotl can mimic any sounds it has heard, including voices. A creature that hears the sounds can tell they are imitations with a successful DC 13 Wisdom (Insight) check. If the target is of a good alignment, it has disadvantage on the check.
Hold Breath. The ahuizotl can hold its breath for 1 hour.
Matted Fur. If a creature touches the ahuizotl or hits it with a melee attack while within 5 feet of it, it is grappled (escape DC 15). Until this grapple ends the target is restrained. The ahuizotl can only have one creature caught in its fur at a time.
Surprise Attack. If the ahuizotl surprises a creature and hits it with an attack during the first round of combat, the target takes an extra 7 (2d6) damage from the attack.
Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) slashing damage.
Strangle. The ahuizotl makes a grapple attempt (escape DC 15). While grappled, a creature is restrained and must succeed a DC 13 Constitution saving throw on each of the ahuizotl's turns. On a failed save, the creature is incapacitated until the end of its next turn and loses 11 (2d10) hit points from choking. On a successful save, the target is not incapacitated and loses half as many hit points.
Ahuizotl are riverbank predators that lurk under the water and pull their prey beneath. With an appearance similar to a small dog, the ahuizotl has streaks across its head, small ears, waterproof fur, and a large hand on the end of its long tail. They prey on good-hearted souls by mimicking the sound of a woman or child in danger, and when they come within reach of the tail, grab them by the throat, drag them underwater and choke the life from them so they may feed.
