Sunny is the main character of the show.
Sunny is the owner of the hair salon. Her full name is Sunny Day. She is in charge of styling and cutting customers' hair. Her best friends are Doodle, Rox, and Blair. Her catchphrase, which she says whenever she's finished styling someone's hair, is "Have a Sunny day!"
Sunny's name reflects her personality and attitude: she has a very sunny, or cheerful, disposition. As said in the theme song, she is perseverant and never gives up. She is the most serious and sincere employee at the salon, which is probably why she is the unofficial leader of her friends.
Sunny has golden blonde hair with bright scarlet and purple highlights. She wears a blue button-down shirt with a pink collar, matching blue tights, and a yellow/red frill skirt. Whenever she needs to "gear up and go" on a mission, she puts on a pink toolbelt that holds all kind of hair products.
