New mob idea, Sea Angels

Heres a new mob called the Sea Angel, based on… well, a Sea Angel. These cute things live in all types of deep oceans, whether it be frozen, cold, warm, or lukewarm. These mobs are translucent and emit a light level of 7. Most of the time this mob will be minding its business, just relaxing and swimming around. But if it sees a drowned holding a nautilus shell, they will start to attack. Weirdly enough, they only attack the drowneds holding nautilus shells and not the ones holding tridents or have nothing in their hands.
