Sea Swirl

Sea Swirl is a female unicorn pony with a lilac coat, iris mane and tail with a light glaucous streak, raspberry rose eyes, and a cutie mark of two encircling dolphins; one light glaucous and one iris. Her name has not been used on the show, but she is named in merchandise. She shares her design with Minuette and Peachy Pitt. Sea Swirl mouths the word "muffins" along with other ponies in Applebuck Season and has a speaking role in The Cutie Pox.

Merchandise
A mini-figure toy named Sea Swirl was released in January 2012 as part of the third wave of mystery packs. The toy uses the Rarity mold but features Sea Swirl's color scheme—albeit with red-orange eyes instead of rose—and cutie mark. Her name comes from the mystery pack packaging and collector card. According to the European version of the card, Sea Swirl "loves the sea". The U.S. version of the card lists Sea Swirl's name with a trademark symbol and has a longer description reading, "SEA SWIRL loves to go swimming in the ocean!"

A second Sea Swirl mini-figure toy and collector card pair was released in November 2013 as part of the ninth wave of mystery packs, which also lists her name with a trademark symbol.

Sea Swirl also appears with her name listed with a trademark symbol in Enterplay's collectible card game, in which she is simultaneously referred to by name and depicted with the same design and eye color as in the show. Her card α #93 R gives her the description "Sea Swirl loves living in Ponyville, but she still takes regular train rides to go swim in the ocean whenever she can take a couple days to herself."

Sea Swirl appears standing next to Noteworthy on page 19 of the upcoming book Winning Style.
