The mbielu can hold its breath for 30 minutes. \n'b'  Toxic Skin . A creature that touches the mbielu or hits it with a  melee attack  while within 5 feet of it takes 2 (1d4) poison damage and must succeed on a DC 13  Constitution  saving throw or be  poisoned  for 1 minute. While  poisoned  in this way, a creature has disadvantage on  Intelligence ,  Wisdom , and  Charisma  saving throws as it experiences mild hallucinations. The  poisoned  creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. \n'b'\n'b' ACTIONS \n'b'\n'b'  Tail .  Melee Weapon Attack : +6 to hit, reach 10 ft., one target.  Hit : 20 (3d10 + 4) bludgeoning damage plus 2 (1d4) poison damage. If the target is a Large or smaller creature, it must succeed on a DC 13  Strength  saving throw or be forced  prone . \n'b'  Rumbling Bellow (Recharge 5\xe2\x80\x936) . The mbielu releases a deep bellow that vibrates within the bodies of those nearby. Each creature within 15 feet of the mbielu must make a DC 13  Constitution  saving throw, taking 18 (4d8) thunder damage on a failed save, or half as much damage on a successful one. If a creature  poisoned  by the mbielu\xe2\x80\x99s Toxic Skin fails this saving throw, it is also  incapacitated  until the end of its next turn as the combined vibrations and hallucinations disorient it. \n'b'\n'b' ABOUT \n'b' This lumbering saurian quadruped has large, oblong plates of bone covered in greenish slime protruding from its back and its thick, club-like tail. \n'b'  Large plates . People describe this reptilian herbivore as \xe2\x80\x9cthe animal with planks growing out of its back.\xe2\x80\x9d The mbielu is a large  dinosaur  akin to a stegosaurus, with square dorsal plates that support symbiotic colonies of toxic, green algae. The plates themselves are as large as shields. \n'b'  Aquatic Herbivore . An mbielu spends most of its life underwater, feeding on aquatic plants and avoiding the withering glare of the harsh sun, but it comes onto land frequently to sun itself for a few hours before immersing itself once again. \n'b'  Toxic Alchemy . Its dorsal plate algae undergo an alchemical  reaction  in the continual transition between water and sky, especially during mbielu migrations to new watery dens. The algae produce a hallucinogenic poison that clouds the minds of most creatures. Mbielus themselves are immune to the toxin.'
