"Excuse me, Phineas. Can I get you to sign some liability waivers?"
— Katie[src]

Katie is one of the Fireside Girls in Danville Troop 46231.


She, along with Ginger, Milly, and Holly helped Phineas and Ferb create S'winter ("S'Winter"). She also helped in building the time machine with the rest of the troop to rescue Phineas, Ferb, and Candace ("It's About Time!"). She and Holly also participated in the Chariot Race with Isabella as their leader ("Greece Lightning").

When Isabella was about to ask Phineas to the Night of the Falling Stars girls' choice dance, Katie interrupted by asking Phineas to sign some liability waivers regarding the upcoming space launch ("Out to Launch").

She sold cupcakes to Heinz Doofenshmirtz on two occasions: once with Gretchen and another with Milly ("Don't Even Blink", "Fireside Girl Jamboree"). She somehow got injured as a result of the Fireside Girls' attempt at running a lemonade stand, shown by her hands and part of her face bandaged up, possibly by paper towels. ("At the Car Wash").
