Synopsis:
A big ship to save the ponies and avoid the unusual floods i.e. the devastating flash floods that could ravage those areas of Equestria. They are willing to face bad weather and floods. Sunny, Hitch, Zipp, Izzy and Pipp want to save them from a very big disaster. The ship is built to accommodate up to thousands of ponies, as well as all paired animals including large and small animals. The ship was built with a more modern design and a replica of an ark ship. At that time, the equestria's magic weakened, and only the remaining magic power every pony had had during the great flood. This magic cannot be used to make rain disappear during a catastrophic flash flood and can only be used to help other ponies outside the ship during a catastrophic flood. The magic will return to normal after the rain subsides and the flood waters stop rising. Sunny and her friends, as well as the ponies, and all the other coupled animals safely boarded the ship to save themselves from the terrible flood. Meanwhile, the rest of the ponies, some among the other ponies, climbed onto their roofs, buildings, and hills to save themselves from the flood. However, the flood waters continued to rise until they drowned those outside the ship. There were a few ponies that survived who were almost carried away by the flood waters by boarding a boat. Until finally, all areas in Equestria were covered with water. The rain has subsided, the flood waters have stopped rising, and the weather is sunny again after the heavy rains. Now, what was once the beautiful land of Equestria has become a clay ocean. Less than a week later, the flood waters began to recede. The mountains, the hills began to appear again. Then the flood waters had receded after a few days later. The flood waters have dried up. Finally they could see the view of the land which had returned to normal after the flood waters had completely receded. They got off the ship. Then they make a new life. Several months later, the ponies including Sunny and friends search for flooded locations with sophisticated technology. They looked for places that had been hit by flood waters until they found a location that had been submerged by flood waters. They remember the city. It was the City of Maretime Bay. Then they looked for other cities, namely Bridlewood and Zephyr Heights.
That's the synopsis of the great flood in Equestria in the My Little Pony G5 franchise.
Nightmare Moon, she is one of the strongest ponies or creatures if she utilizes her magic with extraordinary abilities, namely she can manipulate and conjure Equestria's sea water and basins to warm it, which allows causing the intensity and development of hurricanes that very powerful and very active. Nightmare Moon is stronger than Daybreaker if she is able to manipulate and conjure up Equestria's seawaters and basins become warmer.
Hurricane Fluttershy is a good plot episode for me, it's just that the name Hurricane Fluttershy episode doesn't make sense at all even though the story is good enough for me, because according to or officially by the WMO (The World Meteorological Organization), the hurricane is a weather scale that a large and hurricane is a serious severe weather and serious storm, and a natural disaster. Hurricanes must widen at least about 300 miles or more, even bigger like Typhoon Tip which is the largest hurricane in the world with a width of 2220 km. Hurricanes must be classified if sustained wind speeds have reached 74 mph. Hurricane Patricia is one that reached the peak of the world's fastest sustained wind speed record, which is 215 mph. Moreover, the name of a pony or other creature character that is associated with severe weather and natural disasters, means that the name of the pony or other creature character means that it is not true and in fact it is quite bad or dangerous for Equestria. It's better to have an alternative name for that Hurricane Fluttershy episode.
