Moves that make you think of a mermaid?

Hi all, I have challenged myself to do my first solo performance in October and I am going to be a mermaid. I am currently brainstorming moves and was wondering if there are any moves people can think of that look mermaidy? For example, the corkscrew looks semi mermaid to me as you have your legs together. I am intermediate and can do both spin and static pole :)
