Peppermint Patty

Patricia "Peppermint Patty" Reichardt is a fictional character featured in Charles M. Schulz' comic strip Peanuts. She is one of a small group in the strip who lives across town from Charlie Brown and his school friends (although in The Peanuts Movie she lives in the same neighborhood and attends the same school). She has freckles and auburn/brunette hair and generally displays the characteristics of a tomboy, although that was slightly changed when Marcie was paired with her in There's No Time for Love, Charlie Brown in 1973. She made her first appearance on August 22, 1966. The following year, she made her animated debut in the TV special You're in Love, Charlie Brown and began (in the comics) coaching a baseball team that played against Charlie Brown and since has had other adventures with him. Uniquely, she refers to Charlie Brown and Lucy as "Chuck" and "Lucille", respectively.

As established by a 1970 strip in which Patty's father (who always calls her his "rare gem") gives her roses on her birthday, Peppermint Patty's birthday is October 4th.
