Call of the Sea

It was a dark night on board the ponies pride and a certain pony was heaving her lunch over the side if the ship. "Why did y'all have to make us go with ya on this trip sugercube?  Ah told ya that ah don't do well with the sea."

"Because, Applejack, this research could go on for new breakthroughs for Equistria!" Replied the alicorn.

"Yea, ah guess so Twi." Applejack muttered before she heaved over the side of the ship again. Being a farm pony had its disadvantages, such as getting seasick real easily. Nevertheless she and the other elements of harmony agreed to come with Twilight to see what they can learn of the Chaos Triangle. Legend has it that a secret race can give knowledge and power to those brave enough to face the Triangle, but anypony who went in was either never seen again or came out as insane lunatics. The elements had their own reasons for coming: Rarity wanted to find inspiration for her new line, Pinkie to throw a 'yay we sailed party' at the end of the journey, Fluttershy to learn about the local marine life, Rainbow dash came to see if she can pull off a new trick she has been working on, Applejack to get rid of her seasickness and Twilight to come and see if the legends are true.

Then suddenly the ship lurched, signalling that they arrived in the Chaos triangle. The other elements came out to ask what is happening when they heard angelic voices coming over the side of the ship. They rushed to find out what is making such music to see a pony's head stick out of the water.
