An Evil Deal

Back in the castle it was clear that Celestia was really mad and disappointed.

"I thought I told you not to go to the surface! And you broke that trust! So from now on you are gonna stay here til you marry a merman! You got that?!" Celestia said in rage.

"Yes mother." Twilight replied nervously.

Celestia left and Twilight was pretty upset. She cried hearing that her mom wouldn't let her see the surface and being forced to marry a merman. Then she heard a voice calling her name and followed the sound all the way to the cave. Once in the cave she encountered Suri.

"Hello dearie. I heard you were having a little trouble. Something about mommy not letting you see the surface?" Suri asked.

"Yes. How did you know?" Twilight wondered.

"Cause I was just like you. I used to have a place in the palace and now I'm wasting away. And if you want to see the surface I may consider a deal for you." Suri offered.

"What deal did you have in mind?" Twilight asked.

"Simple. See I noticed that you fallen for this woman named Luna. All you need to do is kiss her by sunset and you'll remain human. But if you don't then you'll turn back into a mermaid and you'll belong to me!" Suri answered. "So do we have a deal?"

"If I'm human I'll never be with my mother again." Twilight noted.

"Life's full of tough choices. Oh and before i forget in return I want your voice in exchange. But don't worry you'll have your looks and charms." Suri added.

"Well....." Twilight thought and sighed. "Okay. Deal."

"It's done then!" Suri said putting the different potion in her Calderon and asked Twilight to sing. She did and two hands of glowing magic took her voice out and sent her to the surface world and gain her human legs. Then Suri turned herself into a woman with Twilight's voice. Now things will really be in trouble.

The Start Under the Sea.

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.

A Motherly Discussion

When the girls arrived back at the Sea Palace they were greeted by the queen herself. She was a white merpony with a mane of pink, blue, and green. She was Celestia.

"Welcome home girls. And Twilight? May I have a word with you?" Celestia said.

"Yes mother." Twilight replied.

The girls all left and Celestia had a stern look on her face.

"Twilight. I just don't know what I'm going to do with you. Do you have any idea how disappointed I am that I had to cancel the celebration?" Celestia asked.

"Sorry mother but I'm ok. Really." Twilight assured.

Celestia sighed. "Young lady listen. As long as you live in this ocean you live under my rules. I don't want you going near any human stuff or the surface again. Is that clear?"

Twilight's cried a little and swam out fast as she could. Celestia sat down and sighed. She then realized that maybe she went too hard on her.

"Maybe I was a bit too hard on her. I just don't want her getting in trouble. I should keep an eye on her." Celestia thought.

So she decided to think it over and also keep an eye on her so she doesn't get in trouble but she didn't realize that two familiar eels were watching and headed back to their mistress.

Part of Your World

Twilight kept swimming til she needed to rest. Then she looked at the treasures she and her friends found and wished that her mother would allow her to see the surface world and know that it isn't bad.

"I don't understand why mother thinks the surface is bad. I just wished that I can help her see that the surface world isn't bad." Twilight said.

She then started to sing a little song.

https://m.

As she was singing about what it would be like to be part of the surface world a woman with blue skin and a mane of stars was listening and decided to follow the sound. Twilight kept singing and her voice was lovely. In fact after she finished the woman found her and Twilight was a little scared.

"Oh I'm sorry miss. I didn't mean to scare you. You had a lovely voice and wanted to see who was singing." The woman replied.

"It's alright. And I never knew that you were so beautiful. I'm Twilight." Twilight introduced.

"I'm Luna. And my you sing beautiful. Like the voice of an angel." Luna said.

"Why thank you. And I appreciate you saying that. You know I really wish I could get to know you." Twilight wished.

"Me too. Maybe tomorrow we can hang out if you like." Luna suggested.

"I like that. Thank you." Twilight replied.

Luna smiled and took her leave. Twilight dunked back into the ocean and swam home. But Celestia stopped her and she wasn't happy. She took Twilight by the arm and went straight to the palace. She was in trouble big time. Meanwhile Suri witnessed it all and formed a plan to get her revenge

Reunited But Too Late

Coming from the ocean Twilight now has human legs and although she can't speak anymore that least she'll be with Luna again. At the same time Luna came back to the beach and saw her. She wasted not a second and ran to her and hugged her tight.

"Twilight! I'm glad you're back! I got so much to tell you!" Luna smiled.

Twilight tried to speak but couldn't since she doesn't have her voice anymore.

"You alright? Hey it's okay. I'm gonna help you. How bout I invite you for dinner and let you meet my friends." Luna suggested.

Twilight could only smile and nodded yes. Luna then decided to give her a tour of the castle and have a little dinner which was great. And to Twilight's surprise she overheard that she wants to marry her and Twilight smiled. But all that hope was crushed when a mysterious woman sang placing Luna under a spell.

The next morning Twilight saw Luna and her servants talking about the wedding that Luna was going to hitched with this mysterious woman. She has black hair like a raven and Twilight's voice. Now Twilight knew something was odd about that woman and then she noticed that it was the sea witch in disguise planning to snatch her woman away! So she needed a plan to stop the wedding.

So she called upon her friends and they crashed the wedding with everyone panicking except for the bishop who is still reading the vows. Then the imposter's butt got bit and she yelled breaking her necklance and Twilight had her voice back and the spell was broken. Luna ran to her and hugged.

"So you can talk after all!" Luna beamed.

"Oh Luna I wanted to tell you for a while now..." Twilight replied.

"Heck no!!" The woman said with Suri's voice.

But just has soon as they were about to kiss the sun settled and Twilight groaned as she turned back into a mermaid meaning it's too late. Then the woman cackled and turned back into the sea witch Suri and everyone screamed and captured Twilight. She then jumped back in the ocean and Luna saw this. She needed to stop that witch and save Twilight.

The Final Fight of the Sea

Suri dragged Twilight to her lair and began to take her soul away. But Celestia showed up and demanded her to set Twilight free. Suri refused and showed the contract she signed. Celestia tried to destroy it but was unbreakable. Then Suri told Celestia that she was willing to make an exchange for her. Leaving Celestia no choice she signed the contract and the deal was done. Twilight was free but costed Celestia her soul and Suri took her crown and trident.

"At last. They're mine!" Suri shouted.

"You monster!" Twilight said enraged.

"Don't toy with me you little brat!!" Suri snarked.

But then she got shot and saw Luna trying to save her. Then Suri tried blasting her with the trident but Twilight made her blast the eels turning them into bits. Suri panicked seeing them dead. She growled in rage and when Twilight swam to Luna she began growing bigger and growling deeper. Above the ocean the two embraced and hugged.

"Luna! You have to get away from here!" Twilight replied.

"No! I'm not leaving you!" Luna said back.

Then a giant crown came out of the ocean and showed us Suri all giant looking and ready to take down the girls.

"You pitiful insufficient fools!!" Suri shouted.

Then began the battle. Since Suri had the trident she controlled the ocean now. And the two were having a very hard time trying to defeat her. Then Luna had an idea. She got on an old boat and steered it into Suri's chest as she groaned in pain as electricity surged through her killing her. Luna somehow managed to get to the beach and survived. Celestia was back to normal and finally realized that she loved Luna. Using her magic she decided to let Twilight go and be human. She smiled knowing her mother was finally accepting her love for Luna. Then Luna married Twilight and together they would be the great couple of the whole world. We cut back to the real world where Spike finished the book saying the last words.

"And like that they lived happily ever after. The End." Spike concluded and put the book away.

"Well that Little Mermaid story really was something. But now it's time for this dragon to get some sleep." Spike said heading to bed.

And that brings another Disney Twiluna story to it's happy conclusion.
