Then she could join WW with the rest of the animals
Or will she be classed as half human half fish?
A New Zealand woman with no legs is having a mermaid's tail made to help her swim.
Nadya Vessey, from Auckland, is having the tail made by the company behind the special effects in Lord of the Rings and King Kong.
She was born with a condition that meant her legs would never develop properly, reports the Stuff news website.
She began swimming after she had her first leg amputated at seven. Despite having her other leg amputated at 16, she swam competitively in high school and now swims as often as she can.
The tail will be moulded on to a pair of wetsuit shorts to make it easy to put on and take off. Vessey says it will allow her to propel herself through the water as if she was a mermaid.
