Mermaid Gilly loves to swim! Adding lots of flips and turns, she never misses an opportunity to put on a show for her friends. Her name is based off the gill, an organ many aquatic animals use to breathe.
Gilly has pink skin and yellow-blonde hair with pink polka dots on one side and a orange-red fringe on the other side, tied up in a single ponytail with pearls and a starfish. One of her arms is orange, while the other is pink with darker pink stripes. She wears two pink seashells as a shirt, and she has a purple tail with pink and orange fins. Her skirt is orange.
