Schroeder, who idolizes Beethoven, brought classical music to the Peanuts strip. Reserved and usually unruffled, Schroeder reacts only when Woodstock tries to make his grand piano into a playground, or Lucy seeks to make it her courting grounds. The latter can lead to minor violence.

Peppermint Patty is a pro on the baseball diamond, but in the classroom she's a D-minus all the way. Bold, brash and tomboyish, what she lacks in common sense she makes up for in sincerity. She's the only one who calls Charlie Brown "Chuck." Oblivious to much that goes on around her, for a long time she seemed unaware that "the funny-looking kid who plays shortstop" was a beagle. She has trouble staying awake in class; most of her waking hours in the schoolroom are spent analyzing the probability patterns of true-false tests.

Marcie is Peppermint Patty's best friend. From the moment they met at summer camp, Marcie has called Peppermint Patty "Sir" out of admiration and misguided manners. An unlikely pair, they seem to have nothing in common yet that is what makes their friendship so genuine. Marcie is the smartest of the Peanuts gang, but also the most naive. She's always willing to help out her friend with school work and she's not above sharing test answers or calling her on the phone to remind her of homework assignments. There is an innocence to Marcie and Peppermint Patty is her protector. Marcie is also completely inept when it comes to sports, yet they still let her play on the baseball team. If Marcie and Peppermint Patty ever have a falling out it's likely to be over Charlie Brown, who they both secretly love.

Before grunge was cool, Pigpen made his debut in the Peanuts comic strip on July 13, 1954 and since then has been the butt of "dirt" gags. He walks around in a cloud of dust, sprinkling dirt on all he comes in contact with. Pigpen is happily messy. He doesn't try to explain it, hide it, fight it. For him, it's just a fact of life. His slovenly ways paid off in 1993 with a series of television commercials for Regina vacuum cleaners which combined animation with live-action.

Franklin met Charlie Brown at the beach in 1968. They'd never met before because they went to different schools, but they had fun playing ball so Charlie Brown invited Franklin to visit him at this house across town for another play session. Later, Franklin turned up as center-fielder on Peppermint Patty's baseball team and sits in front of her at school. Franklin is thoughtful and can quote the Old Testament as effectively as Linus. In contrast with the other characters, Franklin has the fewest anxieties and obsessions. He and Charlie Brown spend quite a bit of time talking about their respective grandfathers. When Franklin first appeared in the late 60s, his noticeably darker skin set some readers in search of a political meaning. However, the remarkable becomes unremarkable when readers learn that Schulz simply introduced Franklin as another character, not a political statement.

Rerun Van Pelt is often mistaken for Linus even though he's his little brother. He can always be recognized in his trademark overalls. Rerun is more skeptical than his brother, much harder to convince, and always gets around Lucy where Linus gives in. His only fear is being the passenger on one of his mother's bicycle-riding errands. Somehow, Rerun is the only witness to her riding into grates and potholes. Luckily, he always wears a helmet. Rerun also longs for a dog of his own, but since his parent won't let him have one, he tries to "borrow" Snoopy from Charlie Brown. Snoopy won't have any part of it unless Rerun brings cookies.
