Spell To Become A Mermaid

I do not vouch for this spell, but maybe, if you want it badly enough, and if the incantation is said with enough power and comviction… ??

While touching water on a full moon or during a solar eclipse say the following:

Mermaid now let it be.
Mermaid when wet so mote it be.
Human when dry so shall it be.
On land I walk.
In the sea I swim with a long_______(tail color) tail.
Blessed be.
And by the power of 3x3x3.
In sea I swim.
When dry I walk.
So mote it be.
So mote it be.
