(A/N) Hello world of fan fiction! First things first, this isn't a crossover with 'The Little Mermaid'. It has some references to it, and also a little bit to 'Peter Pan' but it isn't based off it.
There will be pairings (e.g. Phineas/Isabella, Ferb/Vanessa). And each chapter is a different point of view.
Well, hopefully you enjoy:) Oh, and because I have to:
*Disclaimer* I don't own Phineas and Ferb. Obviously.
Well, now to the story, hope you enjoy:)

Chapter 1

Swim. Bow and wave. Swim again. More bowing. It was always the same old thing. By the end of the day, my fins would ache. But it was what I had to do. The same boring old routine. I sighed and looked out of my window. Sometimes I wished that I could go up there. To the human world I mean. My mother, Queen Vivian, would always warn me and my sisters about getting too close to the surface world. But I dreamed of meeting a human and falling in love. I'd be just like my cousin, Ariel. Although, I'd prefer to pass on losing my voice. I don't think I could go a day without speaking to everyone. Especially the coralside girls. They are my bestest friends in the entire ocean! We all are desperate to explore the world above this water. My sisters, Candace and Vanessa don't share in this desire though. Vanessa is convinced that we will bump into some evil nut-job and Candace, well; let's just say she is a little eccentric when it comes to what she considers 'breaking the rules'. She is always on edge, just in case we get 'busted' as she would put it. We can't get away with anything if she is around. Don't get me wrong, I love my sisters, but sometimes, I wished they shared in my enthusiasm to explore. But until I meet an evil sea witch, I guess I'm stuck here.

I moved to my bed and grabbed a shell off my shelf and started to examine it. Me and the Coralside girls always collected them; we would swim down to the lowest point in the ocean and try and find our perfect shell. Although I had yet to find a 'perfect' one, I had found some rather pretty ones. This was probably my favourite so far. Although it looked a little plain, it certainly had a lot of beauty. It was white at the top, but faded out into a pastel purple colour at the tips. It was similar to my tail really. Except my tail started off a deep purple, but faded into a pastel at the tips. I returned to my spot at the window, and tried to look up at the surface, however an unfamiliar object was blocking my view.
