Liz!", "As I always say", "To the bus!" or "Wahoo!". Valerie appears in The Magic School Bus Rides Again as "Professor Valerie Felicity Frizzle, Ph.D.", with Tomlin once again providing her voice. In this series, she answers phone calls in the call-in segments (replacing the producers scene in the original series) along with her pet monkey named Goldie, and usually gives some clue as to the topic of the next episode. Mostly, in the new series, she sometimes but not always shows up, and is always known for being shown at the ending. Fiona Felicity Frizzle Voiced by Kate McKinnon Fiona Felicity Frizzle is Valerie Frizzle's younger sister and the class's new teacher.

In "In a Pickle", she is the supposed "Judge" in Ms. Frizzle's trial for stealing Keesha's first prize cucumber/turning it into a pickle; she wears the wig, and the outfit, and carries the gavel. While Liz is mute on the show, she speaks in the CD-ROMs (although it appears that only the player can hear her). She is also seen at the end of most episodes with the producers of the Magic
