Once upon a time, there was a girl named Isabella. She loved the sea and beaches. Her dream was to visit a beach one day where she could make sand castles, listen to the waves of the sea and swim to her heart's desire. Overall, she wanted to spend one whole day near the beach. Her wish came true on her ninth birthday, when her parents told her that they were taking her to Krabi, Thailand. She jumped with excitement! This was the best birthday gift ever. She helped her mother in packing their bags and off they went to Thailand.

On reaching the Krabi airport, Isabella was very eager to reach the beach resort. She kept on talking about things she would do there and how she was going to spend her day!

Finally, the blissful moment came and Isabella was there, at the beach, watching the blue sea wide-eyed. It was a delightful moment for her. She had brought her favourite, pink swim suit and strolled across the beach. The sand was hot in day-time, so she decided to swim. She always wanted to become a swimmer.

She quickly went to the sea, where the waves touched her feet. It was so lovely. She entered a little deep in the sea when she felt something under her bare foot. She dropped her gaze to find beautiful sea shells! That added to her happiness. She felt the urge to pick them up. She bent down, and started collecting sea shells. She took care that she didn't step on them and break them. After few minutes of collecting glittering sea shells, she saw a unique shell which was shining more than the others. That shell attracted her in some way. Her hands were full of other shells. If she wanted the big shell, she would have to drop the others. She made a decision and dropped the shells, she had collected. Her mom and dad were watching her from the shacks. She waved at them. They smiled. Finally, she picked up the beautiful shell.
It was different. It made her feel different. She had the urge to break it open. She had never felt like this. Her parents were now walking towards her to look what she had found.

With both her hands, she broke the shell and it split into two with no difficulty. A blinding light forced Isabella to shut her eyes and she instantly dropped the shell.

She hadn't passed out. Not according to her anyways. She slowly opened her eyes and her jaw almost dropped to the ground...

It was the most beautiful scenery ever. It looked as if she was deep inside the sea. She looked up and saw small fishes of almost every colour she knew. Pink, yellow, white and even black.

Isabella didn't know what to do. How was she able to breathe underwater? Had she transformed into a fish? No. Humans cannot transform into a fish. She looked at her hands and she looked like a human only. There were no fins on her. She took a deep breath. Yes, in the water. This time it was intentional. She might be breathing in the water since a few moments now but she needed to check how she was able to breathe underwater. After inhaling, she exhaled. She noticed water coming out from her neck. Shit! She had gills. She touched her neck and felt pores. How? How did she have gills?

But the positive side was that she was able to breathe.

Next experiment she did was to move her legs. It was very easy to move in water. It was like she floated inside it. She moved around completely enjoying herself. She was happy. She had always felt that she was meant to be an  aquatic animal. But, her happiness soon turned to fear when she saw a big, transluscent green figure arising from under the ocean.

She froze. Now, she wasn't able to move anymore. Not even able to move a limb.

"Welcome, my daughter, welcome in my domain." the huge figure spoke.

He looked like a king or something. He was transluscent, meaning that Isabella could see right through him. But, a strange thing she noticed was that the fishes which were coming his way, instantly turned around after noticing him. It meant that we certainly couldn't pass through him!

"Daughter?" asked Isabella, confused.

"I," he said proudly, "am the God of the seas and storms. I am Poseidon! And you are my daughter Bella"

Isabella didn't understand a word of it. She had never heard of such a strange name: Poseidon. And the other thing was how this person or something knew who she was.

"You doubt me." said the big figure bending towards her that she flinched away.

Ofcourse she doubted him.

"Come on. I'll show you your castle." he said, instantly changing into his human form making Isabella gasp. He held her hand and suddenly Isabella was standing infront of a huge castle. She tried to count the number of storeys it had but failed. It was very big and mermaids were floating around.

One mermaid swam towards them. She floated infront of them, smilingly and she pulled a glass filled with red shimmering liquid nearly out of nowhere. Are mermaids magical? Was this a weird dream? It was good as well as shocking for Isabella. Isabella took the shimmering glass and looked at it curiously. The mermaid went away gracefully.

Her so-called father said, "Drink it, my dear."

Isabella reluctantly drank it and instantly felt good. It felt that she was meant to be in this place.

After reaching inside the castle, she was given a very special treatment. Poseidon sat beside her looking at her lovingly. The castle was huge from inside. There were beautiful shells hanging from the ceiling. They were attached by a series of pearls which gave a beautiful look. Isabella, was then presented with a very delicious looking food. She gobbled up everything, afraid that it would vanish any moment. She hadn't imagined this even in her best dreams. After food, it was time for entertainment. The mermaids moved around at first and did back-flips which Isabella guessed was a kind of a dance. It also looked as if they were singing because the water was taking different colours and shapes near them, making the show more joyful! After few minutes, they dragged Isabella to dance too. Isabella laughed her heart out and enjoyed very much. They all danced for nearly half an hour and it was immense fun!

Isabella went back to where Poseidon was sitting.

"Um... Can I ask you something?" she said.

Poseidon nodded.

"How come I got here?"

"Because of 'The Magical Shell' dear." answered Poseidon.

And with that everything was gone. Poof!

"Bella! Bella dear! Get up baby."

Isabella opened her eyes. She was back on sand. Was everything she saw real? Was she really a daughter of Poseidon? She sat up, shocked. She coughed out some salty water. Her mother rubbed her back soothingly.

Isabella moved her hands to her neck frantically, to check if the gills were still there.

No gills.

"Come on! It's 7 already." said her dad.

Isabella was too shocked to say anything. Was it a dream after all? But she was almost sure that she broke a shell.

She dreamily walked towards her hut, recalling everything that had happened and turned around one last time to see the sea when she saw something green and transluscent waving at her...
