Sea Swirl

Sea Swirl is a female unicorn pony with a pale pink 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. She has a speaking role in The Cutie Pox, and she mouths the word "muffins" along with other ponies in Applebuck Season.

Depiction in the series
Sea Swirl is commonly featured as a background pony. She makes her first appearance in episode 1 at the surprise party that Pinkie Pie throws for Twilight Sparkle in the Ponyville library.

In Cutie Mark Chronicles, she stands on a cloud in the sidelines of the race track in Fluttershy and Rainbow Dash's flashbacks of flight camp, even though she is not a pegasus pony--it was stated by Rainbow Dash in Sonic Rainboom that only pegasus ponies can stand on clouds. However, as proved by Twilight Sparkle in the same episode, a spell exists that enables non-pegasus ponies to accomplish the feat, making the circumstances around Sea Swirl's station in Cutie Mark Chronicles much more plausible.

She appears in a bowling alley in The Cutie Pox. She has her first speaking role when she makes an exclamation about "a bowling cutie mark", which a colt earns in the scene.

Merchandise
A mystery pack toy was released in November 2011. The toy shares Sea Swirl's color scheme--albeit with red-orange eyes instead of rose--and cutie mark. Her name comes from the card accompanying the toy. According to the toy package, Sea Swirl "loves the sea".
