Another merm! I love drawing these. Did this a while ago, finally got around to posting it.

This is Sidney as a mermaid, with a beta tail. She's my rainbow baby, so she needs something colorful and bright.

I imagine her being a terrible magpie of a merm who likes to explore shipwrecks and take anything that strikes her fancy. A mischievous sort, but tends to be on her own a lot.
