Two Summer-camp sequences involve Charlie Brown and Peppermint Patty, who has decided that Charlie Brown is madly in love with her. Snoopy shows up at camp as well, as does Peppermint Patty’s new permanent sidekick, Marcie.

The eternally mutable Snoopy mostly shakes off his World War I Flying Ace identity and turns into Joe Cool, college hipster extraordinaire. And in three long sequences he writes a fan letter to his favorite author, Miss Helen Sweetstory, then goes on a journey to meet her, and finally enlists Charlie Brown’s help when her latest opus, The Six Bunny-Wunnies Freak Out, falls afoul of censors.

Woodstock attends worm school, falls in love with a worm (perhaps the most doomed unrequited Peanuts love story ever!) and is nearly eaten by the neighbors’ cat… Peppermint Patty is put on trial for another dress code violation and makes a very ill-advised choice in terms of lawyers… Snoopy turns Linus’s blanket into not one but two sportcoats… Lucy hits a home run … and introduced is her baby brother Rerun Van Pelt!
