Jyoti is a new student in Ms. Frizzle's science class and replaced Phoebe, who went back to her old school. Arnold tells her about how the class has an ecosystem and that nothing should change, except her. Jyoti is delighted after she hears stories of their famous- or, for Arnold, "infamous"- field trips. Arnold offers Jyoti Phoebe's old seat, revealing that she went back to her old school.
Jyoti has her dark brown hair in a ponytail, wears a magenta hairband, gold earrings, a lavender and indigo shirt, black shorts, cream socks and purple and white sneakers.
Her signature colours are indigo and magenta.
- She has a strong interest and talent in the fields of technology and engineering.
