Deep

As Willow tumbles over the side of her familys fishing boat during a sea storm, she expectes nothing but death. But here's the thing - she doesn't die. How could that be possible? No normal person would survive a second on the ocean floor in the middle of the ocean. Then again, no normal person could breath under water, like she just discovered. And no normal person, as far as Willow is concerned, has a tail instead of legs.
