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.
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.
Joni is on very friendly terms with Milo but tends to avoid him as others do. When asked if she'd like to sit beside him, Joni politely declined, stating that she'd just gotten the cast off from last time. She nearly declined Zack's invitation to go to Milo's birthday party on grounds that it would be too dangerous but decided to go anyway.
