Marigold is a brunette girl known for bold clothes, cowboy boots, and her hearing aid. In Dragon Overnight, she is shown to wear grandma nighties. Marigold has long hair and usually wears it back in a ponytail.
Marigold shrinks things. Unlike most upside-down magicians, Marigold's power is not identafiable as a variety of one of the five F powers: Flare, Fluxer, Flicker, Flyer, and Fuzzy. She's shrunk her toothbrush, her bed, her grandpa's car, and, once, Lacey Clench. She can't always stop it, and she can't make things big enough. Ms. Starr has taught her to put her hands in her pockets to prevent her from shrinking things, since Marigold shrinks things she touches. Marigold is in tutoring with an unnamed specialist from the University of Maine.
Marigold is a spunky girl who stands up for herself. She wants to master her power. Marigold seems secure with her problems and has no difficulty sharing private details. She misses her parents and is best friends with Willa.
Marigold used to live hours from Dunwiddle, but she moved in with her grandparents to attend Upside-Down Magic class. They let her watch all the TV she wants, but she misses her parents.
