Fishfood

Melanie had always dreamed of becoming a mermaid. Her legs would fuse into a fishtail, she could breathe under water, it would be awesome.
A witch promised her: The moment she touched water, her spell would activate.
It was nothing like she imagined. It hurt! Her legs didn't join, they became belly fins. She grew a scaly, cumbersome fish-tail. She lost her voice and couldn't breathe air. And she grew an ugly fish mouth.
Hungry, she tried to catch little fish, but they were all quicker.
After 3 days bigger fish, found her.
The sharks were also quicker.
And hungry!
