Fin and April have encountered Sharknadoes in Los Angeles and New York City in the United States. Fin, April, and their family and friends travel to Equestria to publish the book "How to Survive a Sharknado". However, while there, a shark storm occurs near Manehattan that the weather pegasi can't control. Fin, April, their grown kids, and the mane six have to travel to Manehatten to stop the Sharknadoes in a way noone has done it before, a sharknado disipating method that has never been tried in Los Angeles nor New York City.
