Raggedy Ann & Andy: A Musical Adventure is a 1977 live-action/animated musical fantasy film loosely adapted from the 1924 novel Raggedy Ann and Andy and the Camel with the Wrinkled Knees. It was directed by Richard Williams, produced by the Bobbs-Merrill Company, and released theatrically by 20th Century Fox. A 1941 short film had previously featured the Raggedy Ann and Andy characters created by Johnny Gruelle. The first feature-length animated musical comedy produced in the United States, the plot follows Raggedy Ann and Andy, who, along with other toys, live in the nursery of a little girl named Marcella. During Marcella's seventh birthday, Babette, from France, is introduced as the new doll from a large package. Meanwhile, the lecherous Captain Contagious kidnaps Babette in his pirate ship and escapes from the nursery. Ann and Andy must explore and find Babette in the Deep Deep Woods to save her.

The film began development when producer Richard Horner chose the characters from a conversation surrounding promotions of children's products. The Bobbs-Merrill Company became its financer, and the film was a stage musical and a live-action television special before it was decided to become an animated film. Director Williams controlled most of production, which lasted for more than two years, budgeting to the cost of $4 million. As a result, the release date was pushed back for an extra three months of work. Joe Raposo contributed all of the music and songs for the film. The film's promotional campaign cost $2 million.

Raggedy Ann & Andy: A Musical Adventure premiered on March 20, 1977, in nine major cities before it was generally released on April 1, 1977, in the United States. It received mixed reviews, with much of the praise going to the animation. Ever since its release, the film only gained a few home video releases and some television broadcasts. The film was adapted by the 1981 drama adaptation and the 1986 Broadway musical, Raggedy Ann. In recent years, it has developed a cult following for its songs and characters.

Marcella returns home and goes to her nursery playroom to put away her favorite doll, Raggedy Ann. When Marcella leaves, the toys come to life, and Ann tells them of the wonders of the outside world. She then shares that it is Marcella's seventh birthday, and the toys notice a large package in the corner. Marcella opens the present to reveal a beautiful bisque doll from Paris, France, named Babette. Ann and the other toys welcome Babette, but she is too homesick. Meanwhile, Captain Contagious notices Babette and he becomes immediately smitten. After tricking Ann into freeing him, he kidnaps Babette with his band of pirates and leaps out of the nursery window. Ann and Andy decide to rescue Babette.

Ann and Andy enter the Deep Deep Woods. As the dolls travel, they meet the Camel with the Wrinkled Knees, a blue stuffed animal who has been abandoned and hallucinates ghostly camels beckoning him to a home. Ann promises that once they find Babette, he may return with them. With Ann and Andy in tow, the Camel chases down the caravan and mindlessly rushes off a cliff. They find themselves in the Taffy Pit, where the Greedy lives. The Greedy explains that he feels unsatisfied despite endlessly eating. He thus attempts to take the candy heart inside Ann, but the toys successfully escape.

The toys then encounter the knight Sir Leonard Looney, who welcomes them to Looney Land. Looney pursues the toys into the court of its monarch, King Koo Koo. Koo Koo laments his tiny stature and explains that he can only grow by laughing at others. He thus intends to keep the toys as his prisoners. The dolls escaped and slipped away in a boat. The furious king follows them with an enormous sea monster, Gazooks.

While sailing, Ann, Andy, and the Camel notice Contagious' ship, only to discover that Babette had become the new captain while imprisoning Contagious. When Ann tries to tell Babette to return, Babette is enraged and has the trio tied to the mast. Meanwhile, Contagious' shackles were successfully unlocked by Queasy and he returns above deck, freeing the others and pledging his love for Babette. King Koo Koo and Gazooks then attacked the ship and seize all but Ann, Babette, and Queasy to subject them to tickles, making the monarch swell to mammoth proportions by laughing. Babette begs for forgiveness, only for her and Ann to be captured and tickled. The dolls realize that King Koo Koo's inflated ego is "full of hot air," and Andy tells Queasy to pop him, which creates a massive explosion that sends them spiraling.

The following day, Marcella discovers the toys lying her backyard. She returns all but the Camel, where Babette apologizes for her actions and accepts Ann's offer of friendship and Contagious' affection. While the heroes are contented, Ann notices the Camel through the window. The dolls welcome him to their family. The next day, Marcella finds the Camel among the dolls and hugs him tightly, accepting him.
