You stop and think for a moment about all of the possibilities that you can achieve. Changing your worst enemy into an pixie permanently, changing yourself into a giant for a little while. Suddenly it hit you. Mermaid's have always been an fantasy of yours ever since you were young and the transformation sequence takes your breath away. You then thought of the perfect person to use it on. After a few second thoughts and some reassurance, you then say.
"Genie, I wish my girlfriend would go through a slow transformation sequence into a permanent mermaid. Each day for a month, she would undergo more and more changes. And there would be no way of changing back. And she wouldn't want make love to anyone but me".
"Granted" replied the Genie. And with a click of his fingers and a puff of smoke, he left you alone in the middle of the living room.
What happens next?
