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!").

Katie has blond hair in two low pigtails with red elastics, green eyes and is light-skinned, and wears a uniform with a red collar with larger shoes and no socks.
