Aris Aquarium is one of the largest aquariums in the state of Canterlot. One of the most talented swimmers and full train dolphins will pull on a show for the people who are attending. The Rainbooms are pumped to see so many animals under the sea with the show ending off with a bang.

However Equestrian Magic transformed the professional divers into mermaids. Fluttershy and her friends must find a way to turn the divers back into their normal selves but then, the magic turned them into mermaids!
