Vivian is a shy girl who has trouble talking to other people, and as a result had no friends. There were also many false stories made up about her, that she was never able to say weren't true because she wasn't brave enough to say so. But after being partnered with Sofia for a project for art class, the two of them eventually became best friends and Sofia helped Vivian become more confident, and overcome her fear of being around and talking to others.
Vivian is musically talented and her favorite instrument is the mandolin. She is also a talented painter and has a hyper-active, baby blue dragon named Crackle.
Vivian appears in "The Shy Princess", and is partnered with Sofia for the dream castle project in art class. Sofia comes over to her castle, where she is greeted by Queen Cecily, Vivian's mother, to work on it. There Vivian reveals that she knows the other girls make up stories about her but due to her shyness, is unable to say anything to them about it. She is also shown to have a love of music, as her castle's music room is her favorite room. She plays the mandolin while Sofia sings and slowly gains more confidence, eventually singing with her new friend. But Vivian is still scared of Amber and the other girls, and during lunch, runs away when they approach the table she and Sofia are sitting at. When Sofia visits her castle to make sure she's okay, Vivian seems to have lost her confidence and says Sofia should do all the talking when they present their project. But Sofia suggests instead of talking about their castle, they could sing about it instead while Vivian plays her mandolin. This idea works out perfectly, and in the end Vivian's musical talent is praised by the other girls, and Amber even says she would like to be friends with her. Hildegard suggests Vivian join the school band due to her musical talents.
In her next appearance, Vivian entered Crackle into a pet competition, Crackle's talent being riding a unicycle on her belly, which she admitted to Sofia that Crackle learned to do on her own.
She has appeared as a background character in several following episodes where she talks with other kids with confidence. In the episode "Princess Butterfly", she was part of the band that played for the All Hallows Eve Ball, alongside Prince Desmond on the accordion, therefore taking Hildegard's advice.
In "Enchanted Science Fair", she was teamed up with Prince Khalid. When their original project got destroyed, the kids raced off to get the one ingredient they needed to complete their projects. While Khalid was more aggressive in the search, Vivian fell back a bit into her shy department quietly asking if what they were doing was right. In the end all three teams worked together to produce an enchanted solar system for the fair.
In "Scrambled Pets" she brought Crackle to school, hoping to let her play in a bigger playground. Unfortunately, thanks to a magic potion Crackle and Clover got mixed up eventually leading to her and her friends to admitting the truth and fixing the problem.
