Chelsea Van Der Zee (voiced by Annie Murphy) is the primary antagonist of the Dreamworks animated film Ruby Gillman, Teenage Kraken.  Chelsea is a popular girl at Ruby's school and is also a mermaid, though she blends in very well with humans.  To recreate her school-going look from the film, you'll need a long red wig, blue crop top, and sparkling pants.  Accessorize with a blue choker necklace, green beaded hoop earrings, and white sneakers.  Lastly, add a dab of light blue fingernail polish.
