Sunny

Appearance
She has fair skin, straight hair with a gradient from cyan to light pink, a slightly sparse, straight fringe adorned with an accessory that strongly resembles a jellyfish's umbrella, and two long pigtails that fade to the final color of the gradient—light pink—at the bottom of her hair. She has bright pink eyes with a white "+" pupil, and wears a navy blue blouse with a cyan jellyfish brooch fastening at the collar. The blouse has white stripes on the collar, the cuffs, and the hem. She wears a skirt with a gradient between navy blue and light cyan and shoes in the same color as her blouse.
It's noticeable that Sunny cares a lot about her friends — Batatinha, Kode, and Yuyu — and despite their major disagreements, even with Névoa, whom Sunny tends to be somewhat suspicious of.
Personality
Sunny demonstrates a neutral, rational, calm, and responsible nature, being the least emotional and most responsible of the group, often considered the "mother" of the group. She has stated many times that she doesn't feel or understand certain types of emotions, especially love; this is probably due to the fact that she never had feelings before becoming human. However, her personality changes completely when she is irritated, striking fear into anyone.

Furthermore, she is very observant and attentive to detail, always paying attention when someone in the group says something interesting, even keeping a personal diary where she records her daily life with the group and notes observations that may be relevant. In the episode SUNNY'S SECRET PLACE, a notebook, similar to a diary, is revealed where she recorded various details, mainly related to the personalities of the group members and her interactions with them. There's a chance that this notebook is the diary mentioned earlier.
Past
Before being teleported by the Staff to Potato's world, Sunny was just a normal jellyfish exploring the abyssal zone of the sea looking for lost things. She says it was cool, but kind of lonely.

We're not sure what Sunny's home planet was. There's a possibility it wasn't Earth, but rather a planet with marine life similar to hers. It's difficult to know, considering she has no records or memories of the world she lived in, beyond the sea. Many theorize that she was some rare or nearly extinct species of jellyfish, since in the second episode of the animated series, Doci reveals that Sunny is millennia old, and in real life, there are no records of any immortal or ancient jellyfish species whose habitat is the abyssal zone of the sea, although there is a real species of jellyfish that is considered immortal.
Powers
Shock: According to Sunny herself in the first video on the Turma da Batatinha channel, she knows how to do everything a jellyfish can do, including the shock ability. An example of this power appears in the video "Our FANS are FANATICS for US!" where she accidentally falls on top of Yuyu and, probably as a defense mechanism of her jellyfish side, gives him a thunderous shock. (However, she does NOT use her powers except when in extreme danger!)
Interesting facts
Previously, the color of his shock was blue, but starting with "THE SWEET TRUTH," his shock began to be yellow.
At the beginning of the channel, the shoes Sunny wore weren't 100% certain. In some images/videos she wore sneakers, in others flats, and in others sandals. After the video THE NEW LOOK of the Potato Gang!, she was always depicted wearing flats. Someone makes a joke about this old confusion in the video (I forgot the video '-' I'll add it here after re-watching ALL of them), where someone says something like "Does Sunny wear sneakers?" and everyone gets a little confused, not knowing if she wears sneakers, flats, or sandals.
She started reading fanfiction to better understand human emotions. It seems to have helped.
