Pepper Mills is a teenage girl featured on Histeria!, voiced by Tress MacNeille. An occasional singer in the Histeria! Kid Chorus, she is a hyperactive teenager who was born in Homewood, Illinois (as mentioned in "Really Oldies But Goodies"). She is almost a polar opposite in terms of personality to co-star Charity Bazaar, driven to adoration for any and all celebrities. As a result of this, she frequently bothers historical celebrities by asking for their autographs. However, Pepper is always getting these historical figures mixed up with pop cultural celebrities, and it's only when she looks at the autograph she's just been given that she realizes she's made a mistake. She also occasionally hosts an interview show titled Pepper's Pep Rally.
