Peppermint Patty is a supporting character in the Peanuts comic strips and a close friend to Charlie Brown, Marcie, and Lucy. She often gives her friends nicknames such as "Chuck" to Charlie Brown and "Lucille" to Lucy. She is even an expert baseball player and finds Marcie calling her "Sir" annoying even if she tells her to stop.
- In some of her Peanuts appearances, she is voiced by a boy.
- In the Winnie the Pooh/Peanuts crossovers, Pooh and his friends get easily annoyed at Peppermint Patty's overconfidence and her unacquainted romance of Charlie Brown, but it doesn't stop them from being good friends to her. And whenever Peppermint Patty accuses Charlie Brown over something like not having romance, Ash would literally slap her in the back of her head as a way of making her behave herself and be nice to Charlie Brown. Sometimes she would say, "Hey, what did I do? What did I do?" or "What did I say? What did I say?"
- Peppermint Patty will appear with any of her fellow 'nuts in a lot fo Barney's adventures.
