|“||Well, I'm glad it was apple sauce today instead of Sloppy Joes.||”|
— Joni after Murphy's law covers her in apple sauce, Spy Little Sister!
She is voiced by Phoebe S. Hughes.
Joni seems to be very accident prone and tends to fall victim to minor incidents of Murphy's Law more often than other students in her class, often over her own carelessness and plain out misfortune.
She's very friendly, and while she avoids Milo over his condition, she doesn't seem to fear him to the extent that other students do, and is forgiving when something goes wrong.
Joni has a round face, prominent lips, and turquoise eyes with visible pupils and eyelashes. She has bangs and wears her thick brown hair in a long ponytail, tied back with a green hairband.
Joni wears a light green sleeveless shirt with a darker green collar alongside a pale colored skirt with vertical stripes in a darker shade. Her shoes are light grey loafers with dark heels and white soles, and she wears a pair of blue earrings.
In The Undergrounders, she attends the field trip to the natural history museum.
In Rooting for the Enemy, she was seen at the football game, she tells Milo she just got her cast off when he asks her to sit with him and Melissa.
In Disaster of My Dreams, she is seen in the halls.
In Spy Little Sister!, she gets covered in applesauce after Milo's robot malfunctions. She accepts his apology and gives him back his robot, only for Amanda to grab her and shake her, harshly exclaiming 'He's Mine!'.
Joni and Milo are classmates. While they're on friendly terms, Joni tends to avoid him over Murphy's law, as most other people do. She politely declined Milo's invitation to sit beside him, and stated that she'd 'just gotten the cast off from last time'. Likewise, she'd nearly declined Zack's invitation to go to Milo's birthday party on the grounds that it would be too dangerous, but decided to go anyway.
In spite of this, she's very friendly towards him. She was very forgiving when a robot he'd built went out of control and landed in her apple sauce, causing the food to cover her face. After stating that she was glad it was apple sauce and not Sloppy Joes, she thanked him for his apology before giving him back his robot.
Zack and Melissa are two of Joni's classmates. She is on friendly terms with them and gave them a cheerful greeting upon running into them outside of school, unaware that 'how has your day been progressing' was a poor choice of words at the time. After they'd left quickly in response, Joni puzzled over what she'd said wrong.
Joni and Amanda are classmates. After Joni had a 'moment' with Milo in the lunchroom, Amanda raced up to her and began shaking her by the shoulders, stating the words 'he's mine' repeatedly.
