I went to go take a bath after I made the cupcakes and I jump into the tub like usual and I wash myself. Once I clean my mane I open my eyes and find a pony with fins in front of me. She was a seapony of course. She introduced herself to me.
"I'm Kelp Coral and I'm a seapony. I come from the deep ocean looking to find a land pony and I finally found her," she said looking at me.
"How did you crawl through the small pipes?" I ask
"You will find out once I pull you down the drain," Kelp looked down.
"I can't fit through there. You can't do that either," I say "Unless I believe,"
I close my eyes as the seapony pulled on my hoof and now feeling the water in my face. There was no air surrounding me anymore. All I could feel was the warm bath water. The water got cooler and cooler as I traveled through the pipe. Then I black out because of lack of air.
I wake up in a pile of kelp on the seafloor. Not knowing how I could breath underwater, I tried to sit up on my hoofs but I didn't have hooves for some reason. I look over and find a Seapony's tail. I was now the pony of the sea. Once I get back to Ponyville and tell Twilight this, she won't believe me.
I still had my puffy mane but not my tail. My front hooves were replaced by fins.
I found Kelp staining there. "You're finally awake. How was your deep sea slumber."
"SUPER! What did you do to me?" I said the first part load and clear.
"I wish I had a spell to help you breath underwater, but turning you into a seapony was the only option to saving your life," Kelp replied.
"It's fine, now I can breath in my bathtub!" I yelled.
"We have to head to the village. There waiting for us there," Kelp smiled.
"Lets go!" I yelled in excitement.
We both headed off to the village.
We arrive in the village 3 hours later. Celestia's day was about to end. I could see the sunlight reflecting in the water so beautifully. The seaponies in the village watch the sunset, now being replaced by Luna's moon. The Seaponies look at the moon and bow.
They must worship the moon down here I thought.
After the bowed the swam up to me and started to get to know me. I do this in Ponyville. I was wondering what its like to have a pony welcoming me. But this was way too much.
"Where are you from?" one asked
"What is it like on land?" another asked.
"CAN WE HAVE A PARTY!?" I asked in a loud voice. Everypony became silent.
"Sure, that's a great idea!" one seapony said
And we all partied hard.
I was parting with the seaponies and that when everything went wrong. Darkness filled the ocean like a poisonous gas. The seaponies where very afraid, they hid behind plains and clams. I just stayed where I was with my eyes closed and dancing. I open them.
"Where did everypony go?" I ask.
"Well, well, well, what do we have here?" said a dark voice. I look behind me and found a sea serpent.
"HI! I'm Pinkie Pie!" I introduced myself. The serpent licked his lips.
"You look tasty. You could make a great snack," he said.
"Well we have plenty of snacks here!" I pointed out. But her kept staring at me.
"Do you want to play a game? I call it smack the pony unconscious so I can eat it game," he said.
"I WANT TO PLAY!" I yelled in excitement.
The serpent wracked me with its tail. I flew into a nearby sea cliff. Then everything went black.
I wake up underwater but in a different place. I wasn't in the dragon's belly but I was inside some type of white tank. I saw the edge of the water above me. I pop my head though the water and found myself back in my tub. Was this all just a dream? Did I fall asleep in the tub? If I did, how long did I say underwater? I rub my neck to find that I still had gills. I found that I still had my seapony tail. I jump out of the tub and I quickly turned back into my original body. Thats why I was still able to breath in Magic Duel.
