Oona is a sweet, sincere, sensitive, and gentle little girl who's empathetic and aware of other people's emotions. Sensitive, Oona would be the most likely to show concern for a sick friend, to notice when someone is feeling down, or to give loving care to a pet or a plant. Her best friend is Nonny, and they frequently play together. When not around Nonny, Oona usually likes to hang out with Deema.
Oona has a great amount of empathy, meaning when someone is sad or unhappy she feels the exact same way. She finds limitless wonder in the world around her and she is normally the person to ask Mr. Grouper a question and is always excited to learn the answer.
When Oona was first seen in the series, she was seen as a outgoing person, but later in the series she was shyer than ususal. Oona is the only guppy out of all of the 6 to be sweet and gentle. Unlike Molly and Deema, she has a fully piece suit. Because of her weight, she has a full piece tail. Oona loves to look after flowers. She'll take care of any animal or an object.
Oona's personality is seen to be shy. She loves to play with the other guppies. She is never afraid of asking questions. Since she is 4 years of age, she is not as intelligent as the other guppies.
Oona is emotional, but she's never seen crying in the show. In Bubble-Cadabra! She was seen very upset because she thought that Goby had dissapeared until after Goby re-reappeared, Oona quickly hugs Goby as an act of love. (See: OonaxGoby).
In Call a Clambulance! Oona was worried about her fish friend named Avi. He broke his tail on the journey to school, and Oona got worried that he might be hurt and might not swim ever again.
In The Spring chicken is coming!, she was upset because her flower didn't bloom before the ceremony. She taught the viewers that patience is the best way for happiness. The Spring Chicken wouldn't announce that it's spring unless she saw a flower. Oona remembers that her flower was behind the bench and then it bloomed right on time; making it spring!
From Season 1 to Season 2, Oona has never been seen angry. She is kind to all creatures, no matter how they look like. Oona is kind to animals, plants, and even paper! She's Eco friendly. In Boy Meets Squirrel!, she asked Mr. Grouper what she should do with the paper. She decided to not throw it away, but to recycle it.
Oona has light tan skin and brown eyes. Her purple hair is worn in two low pigtails, and she wears a pink starfish accessory in her hair. She has a purple tail with wavy pink stripes. Her eyes are almond-shaped instead of round.
There may be a slight possiblity that Oona could be Filipino or Japanese. She had Tofu and a Sushi roll for lunch, giving her a more possible chance of being Japanese. Oona is the most different out of the girls, she wears her hair in pigtails while Deema and Molly have their hair down.
Season 2 Oona
Oona's eyes in season 2 are more almond shaped. This helps the young viewers identify race, since she is Asian or Japanese. The producers could've made her skin lighter and her eyes more oval shaped.
Her body is thicker but the tail is thinner than season 1. The bottom of Oona's tail is thinner than season 1, but around her stomach area, her body is thick, probably due to animations they used.
Her hair is longer. Oona's hair is longer due to growth.
Oona's singing voice is very good. in season 1 Oona's voice wasn't really heard, she'll normally just say her lines other than singing them. Oona has a high pitched voice, best for singing solos, since she's one of the least characters, she's always put in the background. Oona sang a solo in: Call a Clambulance! (See: A bunch of bones).
Oona can dance very well. That's why she's put in some dance songs. Oona doesn't seem to dance that often when she's on her own. She likes to dance with Deema a lot, thlly of what Deema does)ough. Oona follows dance steps (normally what Deema does) as seen in the dance song: Stick out your wings and fly.
Oona's head shape was oval not circle, all of the guppies had similar shaped heads, like Goby's was slightly bigger than the rest, but Oona's head was the thinnest. The colour scheme of her head was Pale Gold instead of Light amber. Oona's hair was shorter in length, and it was still tied up in pgtails but using ribboned hairbands instead of unseen colours. Oona's tail was very thin and she was the thinnest guppy in the early drawing of the Bubble Guppies, Oona had a pink tail. It had polka dot spots on it. Her tail was slightly red aswell.
Like all the guppies in the Beta version, her eyes were round. She wasn't known as Japanese or Filipino, she was just there.
