Pamela Harding is Karen Brewer, Nancy Dawes, and Hannie Papadakis' main enemy. Pamela's best friends are Leslie Morris and Jannie Gilbert, also known as "The Milky Ways" in "Karen's Candy." Karen describes all three as snobby girls.
Pamela is first introduced in "Karen's Sleepover" as a new student in Ms. Colman's class. At first, Karen wants to impress her and become friends with her. Pamela comes to Karen's sleepover party, but it doesn't take long for Karen to realize that Pamela is not fun to be around at all.
Pamela refuses to sleep on the floor, hates the movie "The Wizard of Oz", and claims that pizza "gives" her bad breath.
