Bulbdog

Water-Dwelling. The Bulbdog can hold it's breath for up to 2 hours at a time.

Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) piercing damage.

Enthrall. The Bulbdog causes the bulb at the end of the appendage on its head to emit a mesmerizing light. All creatures of the Bulbdog's choice within 30 feet of it that can see it must make a DC 11 Wisdom saving throw or become Charmed by it. While Charmed in this way, the affected creature(s) are Incapacitated and must move towards the Bulbdog on their turns.

An affected creature can repeat the saving throw at the end of each of it's turns, ending the effect on itself on a success. A creature that saves or otherwise ends the effect of the Bulbdog's Enthrall ability is immune to this effect for the next 24 hours.
