Katrina Peachie

Katrina Peachie is James Stone's 98th Street counterpart and a 42-year-old woman (born 1955) who went undercover at 98th Street School, on the orders of Superintendent Brickly, posing as a new fourth-grade student in C.J. and the gang's class. He appears only in the episode "The Spy Who Came In from the Playground".

Appearance
Katrina is very short for her age easily being mistaken for a child of about nine. Unlike her male counterpart who is bald, she has blonde hair.

In her undercover outfit, Katrina wore a pink knee-length dress, a purple vest, black leather shoes and white socks. She also wore a red cap, and sunglasses to cover the wrinkles around her eyes.

History
The gang immediately befriends Katrina. As time goes by the gang begins to suspect something is awry when their various secrets continue to be found out, and the gang initially blames Rachel for this, but Rachel denies this. The gang then finds out that Peachie, not Rachel, was responsible for this on the orders of Brickly.

Katrina is compared to Benedict Arnold by the gang when they find out about the truth: while posing as a student, Katrina wears sunglasses and a baseball cap to conceal his true identity; in the girls' bathroom, she is revealed to have wrinkles around her eyes.

Upset over the betrayal, the gang decides to teach Peachie a lesson for messing with them. By tricking her into pulling a prank on Brickly involving the flagpole, C.J. gets Rachel to rat out Peachie, for which Rachel thanks C.J. As a result, Brickly angrily fires Peachie and has her arrested. As she is taken away, Peachie swore revenge on the gang.
