Join the Peanuts gang for a timeless adventure as Charlie Brown preps for a party, Snoopy sets his sights on the Red Baron, and Linus patiently awaits a pumpkin patch miracle.

After their humiliating 999th defeat, Charlie Brown's whole baseball team quits on him. All seems lost...until Charlie Brown learns that his team can join the Little League and become an official team with real uniforms! But as the team's enthusiasm sparks, Charlie Brown learns that neither girls nor Snoopy would be allowed to play. Charlie Brown faces the difficult decision of breaking this horrible news to his excited team.

When the gang loses patience with Snoopy's mischief, he suddenly finds himself back in obedience training. With a vengeance, Snoopy decides it's time to run away to Peppermint Patty's house, but soon realizes life might not be so bad with Charlie Brown after all.

School is out for the summer and Charlie Brown, Linus, Schroeder and Pig Pen are planning to spend it reading every comic book, watching television, practicing ballplay, and classical music, and having clean thoughts. However, Lucy tells them that she signed them up for camp. The girls are eager to go, but the boys hate the idea.(Linus adding that its like finding out that he was drafted.) The boys shove each other to get on the bus, while the girls line up in order. At camp, Charlie Brown is chosen captain of the boys camp. The boys and girls have a swim race which the girls win easily. Then they have a softball game, which the boys lose with only one run. Other competitions are just as lopsided. Afterwards, the boys sit around the campfire and reflect on how miserable they are. In one scene, the colors of the shirts of Schroder and Linus are mixed up during this scene.

With the school year coming to a close, Charlie Brown is trying to work up the courage to meet his dream girl, whom he only knows as "The Little Red Haired Girl." However, he's too nervous to go meet her upfront and all his attempts to impress her at school backfire disastrously. His friends, Linus and Peppermint Patty, try to help, but only aggravate the situation, while Charlie Brown desperately tries to find a solution to this romantic conundrum.
