Morgan's miracle involves a Miracle Flute that can transmit the Miracle Power through sound.
The Power of Folly doesn't just affect aquatic creatures, it also covers the animals and plants on land, it's just that compared to the inherently flowing water, air as a medium has obvious limitations.
Because of cost-effectiveness, Morgan abandoned the land beasts and instead specialized in the flora and fauna deep beneath the sea.
Aquatic life is vast and varied; not counting plants, there are also cnidarians, mollusks, crustaceans, mammals, and the most common fish.
Cnidarian animals refer to sea anemones, jellyfish, corals, starfish, and similar seemingly plant-like marine life, which, when mutated, mostly grow to a massive size and evolve various elemental forges within.
Their destructive power is comparable to the crimson crab, capable of launching devastating attacks akin to nuclear bombs.
Alas, their law conversion efficiency is exceedingly low.
