Ms. Fiona Frizzle



Fiona Felicity Frizzle is Valerie Frizzle's younger sister and the class' new teacher. She borrows a lot of her big sister's catchphrases, including "Bus, do your stuff!", among many others. Similar to her sister, her skirt and necklace often change each episode based on the topic. As a parallel to her sister's "as I always say" catchphrase, she often quotes random relatives and friends of hers.
