Ludivine

A 4'11" princess of sharks in the sea. Once she started seeing sailors, Ludivine grew intrigued and wanted to see what the human world was like!!!!. When she ended up beached on a shore, a witch found her and helped her transform into a human. 

Because she's royalty, she has quite an ego and a mean streak, and doesn't realize when she's upsetting other people (because it's funny to her!!!).
