Mindy is a girl living in the city of Danville, and a rival to schoolmate Candace Flynn. She shows interest in Jeremy Johnson when asking him to sit next to her under Phineas and Ferb's circus. However, Jeremy does not seem to like her in the same way, as he tells her that he is going to sit next to Candace. ("Jerk De Soleil")
She is also the first person to see Candace in Goth-styled clothes, after an unwanted switch with Vanessa Doofenshmirtz. The first thing she does is to take a picture with her phone and send it to all her contacts, stating, "Wow, fifty replies already!", despite Candace obviously not wanting anyone to see her. ("Hail Doofania!")
Mindy has short blond hair with a blue hair clip. She wears a green short-sleeved shirt with neon green and yellow swirls on it over a blue long-sleeved shirt and faded pale green leggings.
