The swarm can breathe air and water. \n'b'  Freeze . If the swarm takes cold damage, it partially freezes; its speed is reduced by 20 feet until the end of its next turn. \n'b'  Swarm . The swarm can occupy another creature\xe2\x80\x99s space and vice versa, and the swarm can move through any opening large enough for a Small humanoid. The swarm can\xe2\x80\x99t regain  hit points  or gain  temporary hit points . \n'b'  Water Form . The swarm can enter a hostile creature\xe2\x80\x99s space and stop there. It can move through a space as narrow as 1 inch wide without squeezing. \n'b'\n'b' ACTIONS \n'b'\n'b'  Frightful Presence . Each creature of the swarm\xe2\x80\x99s choice that is within 120 feet of the swarm and aware of it must succeed on a DC 13  Wisdom  saving throw or become  frightened  for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature\xe2\x80\x99s saving throw is successful or the effect ends for it, the creature is immune to the swarm\xe2\x80\x99s Frightful Presence for the next 24 hours. \n'b'  Spears .

The head is as large as a whole elephant with a long curling silver tongue and darting green fangs. But it\xe2\x80\x99s teeth make it clear this is no ordinary serpent. Each tooth of this singular sea serpent is a live white goblin brandishing a long spear. Leaning far out of the yawning mouth, they scream, hiss and yell. \n'b' Sea goblins are a rare form of  elemental  that come together for a singular purpose: to feed. A minor threat on their own, sea goblins are ferocious when fully assembled into their sea serpent form. \n'b'  Not Goblins \xe2\x80\xa6 Sea goblins are curiously misnamed, no doubt in part due to their horned,  goblin -like appearance. \n'b' Made of water, these bizarre monsters float about in the ocean, terrorizing all they encounter. Their immunities makes them a threat to most beasts, and their lack of organization makes them poor troops. \n'b'  \xe2\x80\xa6 But Not Serpents . It\xe2\x80\x99s when sea goblins get together that they become a danger to even sailing vessels. Sea goblins have an instinctive urge to bind with others of their kind, and it drives them into a frenzy. They transform into a coiling serpent-like form that willfully attacks anything large enough to catch its notice.'
