We begin our story under the ocean where we see a purple sea pony swimming around with her friends. She was Twilight Sparkle. Her friends are Rarity, Fluttershy, Rainbow Dash, Applejack, Pinkie Pie, and Fluttershy. They were residents of Seaquestria and were loving everything that had to offer them. Then Rarity noticed Twilight was a little sad.
"What's wrong Twilight?" Rarity asked.
"Well I just wish I had someone. Don't get me wrong I love hanging out with you girls. But I wish I had a special someone." Twilight answered.
"Don't worry Twilight. One day you'll find a special handsome merman to treat you like a princess." Rarity assured.
Then Twilight followed Rarity to meet up with the other girls. But Twilight had a different love experience. See her mother Queen Celestia wanted her to pick a merman but she didn't want that. Deep down she prefers to have a lovely woman. But anyways they all travelled to a sunken ship and found many treasures to have. But none of them realize that an evil sea witch named was watching. Her name was Suri Polomare. She had an octopus dress and purple hair and was watching them through a bubble.
"Yes. Swim back to mommy. You wouldn't want to miss her party do you? In my day I would enjoy the party when I was in the palace. Now look at me. Wasted away. If it's a party they want then I'll give them something to party. Flatsam! Jetsam!" Suri shouted as two eels came to her.
"Keep an eye on Celestia's daughter. I think she may be the key to her undoing." Suri grinned.
The sea witch had a plan and can only mean trouble.
