"It´s finally done girls! I´ve created a spell that allows us to breathe underwater!" Twilight proudly announced.

"YEAH! Finally I can throw my swimsuit party!!" Pinkie Pie yelled, pulling the bikinis out of nowhere.

"Sounds like fun." Rainbow Dash said, referring to the swimsuits.

"Indeed. This will be a perfect opportunity to study underwater life." Twilight conceded levitating her notepad. "Fluttershy, I´m looking forward for you helping me communicate with the animals down there."

"Oh please Twilight, everypony knows that fish are just food."

"...okay."

"I can´t wait to get my hooves in some nice shiny pearls." Rarity added.

"Then let´s get our package ready. We´ll sail, so to speak, tomorrow morning."

"Euh Twi- ah think ah´ll pass on this one. Ah ha-have work in the farm, yah know...apples." Applejack said, looking white.

"What´s the matter, AJ? Afraid of water?" Rainbow teased her.

"Don´t worry Applejack, the fact that you can´t swim at all won´t affect our mission. You can just stay on the bubble." Twilight said.

"Jeez. Thanks for keeping a secret, sugarcube."

"Everypony ready?"

"YES!"

"...no."

*****

Ignoring Applejack´s complaints, the next morning the mane six and Spike were ready to dive into the unknowns deeps using the magical bubble created by Twilight. Although Twilight assured them they wouldn't need to swim, Pinkie insisted on them wearing bikinis, Rarity one causing Spike to remain unconscious the entire time.

Once they descended enough, they found a city build out of coral and inhabited by mermaid like ponies.

"Oh my Celestia, the legends were true! Sea-ponies!" Twilight saidenthusiasticc.

Shoo-be-doo shoo-shoo-be-doo!

"This is going to be so much fun!!" Pinkie chirped.

****

Shoo-be-doo Shoo-shoo-be-doo!

"This sea-ponies are fascinating! Not to mention very welcoming." Twilight said while marking some item on her list.

"I must said their taste in fashion is simply delightful!" Rarity added, covered in pearls.

"Their culture is simply fascinating and everypony seems to be having a wonderful time in here, right Applejack?"

"..." the blank stare of the earth pony said enough.

"Yeah, we´re having fun."

Shoo-be-doo!

****

"Dear Princess Celestia it´s been two days since we discovered the sea-ponies." Twilight said while writing her own letter due to SPike being out of service. "Although seaweed is not exactly my favorite we´re still enjoying it in here, right Applejack?"

"..."

"Yeah, even Rainbow Dash who I think would dislkie the water is engaged to their underwater races, insisting on being the fates on land, sky and water. I´m eager to return home and give you a full report on their cult- Fluttershy, stop chewing on their tails!"

Shoo-be-doo!

***

Sho-sho-be-dooo!

"Dear Princess Celestia...I CAN´T TAKE IT ANYMORE!! All they do all day is singing and swimming and singing. I´m going crazy in here and my friends do nothing to help! Rarity does nothing but roll on the pearls all day, Rainbow Dash just doesn't know when to give up and keeps circling on those silly races, Applejack is useless...

"..."

"Pinkie got sick after eating seaweed and Fluttershy keeps trying to eat this ponies whom, should I add,a re incredible annoying! They´re not fascinating, they´re obnoxious!"

Shoo-shoo-be-doo!

"ARGH! That´s it we´re out of here!" and Twilight teleported all of them back to dry land.

The sea-ponies watched the magical bubble burst and finally let themselves breathe in relief.

"Finally they´re gone!" one of them said.

"Thank Oceanis, I couldn't take them anymore! That pink pony never shuts up!" another said.

"And that pegasus? It was all me, me, me, me! So annoying!" yet another one said.

"I liked the orange one." a sea pony wearing a sailor cap said.

"Enough girls! Now that we´ve have get rid of those characters we can focus on stopping the evil Tidal Wave for destroying Portssnout!Let´s go!" the leader of the sea-ponies said.

and thus the sea-ponies leave to have many adventures...that we will never see.
