Bestiary Entry
Small, aquatic creature that originates from the Frozen Ocean. A thick and insulated shell serves to protect and keep it warm. Some can grow to immense sizes, and even when at their largest natural size, can mutate to become far bigger. Due to their extremely long lifespan, they are feared by Goblins, Terrarians and other sea creatures alike, and are hunted down in fear that one day, they might overpopulate and conquer the seas.
