Info:

In a normal day, 3 teenagers fall into a pool in a no-longer working volcano, which is mostly an island now, and watch as the water bubbles in the sight of the full moon up above.
What happens when they become mermaids, and see their tail every time they interact with water?
What happens when they get powers?
Will they meet other mermaids?
At all cost, they must keep this a secret!

I DON'T OWN ANY OF THE CHARACTERS IN H2O!
