In the ocean, near the equator, there is a small coral atoll.
Although there is little interesting on the Islands themselves, the warm, crystal-clear waters cover the whole world.
Flocks of colorful fish and shrimps scurry about their business and curiously poke their noses at any object of interest to them.
Like bright flowers, the burning tentacles of sea anemones and anemones are spreading, and the sea grasses are swaying like silk curtains.
Fluttershy, having heard about the beauty of underwater nature, could not remain indifferent. And when she was lucky enough to go on an ocean cruise, the yellow pegasus decided to get acquainted with the underwater world closer. And, what is especially pleasant, Princess Cadence, who was traveling on the same liner, gave her an enchanted breathing mask and a swimsuit.
