|“||They want Sextina Aquafina, baby!||”|
—Sextina Aquafina, Prickly-Muffin
Sextina is a light blue dolphin. Unlike real-life dolphins, she has human arms and legs. She wears eyeliner and lipstick. The colors of her makeup and her outfits vary from scenes and episodes.
Little is known about Sextina's background. She was born in early or late 2000.
In a flashback from 2014, in Prickly-Muffin, A Ryan Seacrest Type describes Sextina as "a fourteen-year-old teenage dubstep wunderkind." She states in her interview, with A Ryan Seacrest Type, that she was a big fan of Sarah Lynn growing up.
The resulting controversy helps Sextina's career, so she decides to carry on pretending.
Sextina's tweet and music video, end up being inspiring and even educational, to many women. When Diane goes to for her abortion, a woman at the abortion clinic, says it helped her feel less alone.
In the end, Sextina actually becomes pregnant and wants to keep the baby. As a result, Diane and Princess Carolyn work together, to hide this pregnancy. They also strategize, on how to keep Sextina relevant in the public eye, while she goes incognito.
She appears in the background of Princess Carolyn's wedding during Nice While It Lasted.
