Multiattack. The banderhobb makes one Bite attack and one Tongue attack. It can replace one attack with a use of Shadow Step.

Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 15 (3d6 + 5) piercing damage, and the target is grappled (escape DC 16) if it is a Large or smaller creature. Until this grapple ends, the target is restrained, and the banderhobb can't use its Bite attack or Tongue attack on another target.

Tongue. Melee Weapon Attack: +8 to hit, reach 15 ft., one creature. Hit: 10 (3d6) necrotic damage, and the target must make a DC 16 Strength saving throw. On a failed save, the target is pulled to a space within 5 feet of the banderhobb.

Shadow Step. The banderhobb teleports up to 30 feet to an unoccupied space of dim light or darkness that it can see.

Swallow. Melee Weapon Attack: +8 to hit, reach 5 ft., one Medium or smaller creature grappled by the banderhobb. Hit: 15 (3d6 + 5) piercing damage. The creature is also swallowed, and the grapple ends. The swallowed creature is blinded and restrained, it has 3 against attacks and other effects outside the banderhobb, and it takes 10 (3d6) necrotic damage at the start of each of the banderhobb's turns. A creature reduced to 0 hit points in this way stops taking the necrotic damage and becomes stable. The banderhobb can have only one creature swallowed at a time. While the banderhobb isn't incapacitated, it can regurgitate the creature at any time (no action required) in a space within 5 feet of it. The creature exits prone. If the banderhobb dies, it likewise regurgitates a swallowed creature.

Shadow Stealth. While in dim light or darkness, the banderhobb takes the Hide action.
