Act I
Scene 1
During the Overture, Woodstock energetically enters and sets the scene, introducing Charlie Brown and the rest of the Peanuts gang. Together, they celebrate "The World According to Snoopy." After his grand introduction, Snoopy laments the monotony and repetition of his daily life (“Snoopy’s Song”). But he changes his mind after Lucy suggests that Charlie Brown trade him in for a couple of goldfish. After a few brief comic vignettes, Woodstock falls in love with a worm (“Woodstock’s Theme”). Snoopy remarks, “That’s like me falling in love with a can of dog food.” But it doesn’t last long: Woodstock’s wormfriend runs off with the early bird. Sally enlists snoopy's help in writing an essay on her Best Animal Friend.
Scene 2
In school, Sally excels presents a report on Rain, Peppermint Patty gets carried away in answering true-or-false questions, Linus waxes poetic on his summer vacation, and Lucy applies her math skills to Louis the Fourteenth, and Charlie Brown reads a very brief report on Columbus. But mostly, the entire class agonizes over “Edgar Allen Poe.”
Scene 3
Charlie Brown finds a note in his pants pocket and wonders whether it's from the little redheaded girl. But it's just an inspection ticket from the pants factory. Lucy asks Peppermint Patty and Sally, “Wouldn’t it be wonderful to have your whole life to live over if you knew what you know now?” and the three girls celebrate the breadth of their knowledge (“I Know Now”).
Scene 4
On Halloween, Linus sits all night in the pumpkin patch, awaiting the arrival of the Great Pumpkin (“The Vigil”). Peppermint Patty remains skeptical.
Scene 5
After a few brief vignettes, Snoopy enters as the Easter Beagle, distributing colored eggs to everyone… except Charlie Brown. Charlie Brown, musing on the new independence of his pet, wonders "Where Did That Little Dog Go?" Lucy, Patty and Sally declare that dogs like Snoopy are a “Dime A Dozen.”
Scene 6
Snoopy nostalgically recalls his days at the puppy farm ("Daisy Hill") and settles into his favorite position: reclining on his doghouse with his head in the water dish. Lucy, grumbling about this boring town, wonders “When Do The Good Things Start?” Her question develops into a spirited musical number, ending with the whole gang singing, “How about if some good things start right now!”
Act II
Scene 1
After the Entr'acte, during which Woodstock builds himself a nest, Snoopy and the Peanuts gang celebrate their friendship ("Friends").

Scene 3
At Lucy’s five-cent psychiatric booth, Charlie Brown wishes someone would say they like him, but Lucy simply can’t do it.
Scene 4
Snoopy, as Joe Cool, would rather chase chicks than sticks. Linus endures a painful separation from his blanket as Lucy runs it through the wash cycle.
Scene 5
Peppermint Patty asks Charlie Brown to explain love to her, and he describes the kind of girl he’d like to marry: someone who’d call him “Poor Sweet Baby.” Patty sings a lovely, affectionate song to Charlie Brown, and then says, “Forget it. It’ll never happen.” Inspired by the resilient cycle of nature, Sally leads the gang in a rousing song called “Don’t Be Anything Less Than Everything You Can Be.”
Scene 6
Snoopy sells tickets at a Movie Box Office, and everyone has an opinion about the film. Sally dreams about a future with Linus ("Husband Material").
Scene 7
Woodstock delivers a letter naming Snoopy “Head Beagle.” Snoopy proudly accepts the honor (“The Big Bow-Wow”).
Scene 8
Everyone begins preparing for Christmas: Woodstock and Snoopy decorate the doghouse, Lucy writes to Santa, requesting cash, and Charlie Brown admires the stars at Christmas time. He believes there’s one star out there that is his star, prompting Linus to ask, “Wouldn’t it be wonderful if everybody believed in everybody else?” Lucy scoffs at believing in someone like Charlie Brown, but Snoopy admits, “You gotta start someplace.” He begins to sing, and one by one, the kids join in. Soon the entire gang is holding hands and singing together (“Just One Person”).
Charlie Brown pets Snoopy and puts him to bed, saying, "He isn't much of a dog. But after all, who is?" Snoopy sighs and settles into sleep as the lights fade.
