George has the submarine's motor, Paul has "a little 'love'," and Ringo has "half a hole" in his pocket (having apparently given the other half to Jeremy). The real Beatles then appear in live-action, and playfully show off souvenirs from the events of the film. An enormous party ensues (" It's All Too Much"). John extends an offer of friendship, and the Chief Blue Meanie has a change of heart and accepts.

Jeremy performs some "transformation magic" on the Chief Blue Meanie, causing the Meanie to bloom roses and sadly concede defeat. Pepper's Lonely Hearts Club Band are released due to Ringo's hole, and join the Beatles in combating the Meanies' multi-headed dog (" Hey Bulldog"). Pepperland is restored to colour as its flowers re-bloom and its residents revive. The Chief Blue Meanie retaliates by sending out the Dreadful Flying Glove, which John defeats by singing " All You Need Is Love". The four rally the land to rebellion (" Sgt. Pepper's Lonely Hearts Club Band and steal some instruments. Reuniting with Old Fred and reviving the Lord Mayor, they look upon the now-miserable, grey landscape. Jeremy is kidnapped by a Blue Meanie, and the group finds their way to Pepperland. They then find themselves in the Sea of Holes, an expanse of flat surfaces with many holes, Ringo takes one for himself. They arrive at the Foothills of the Headlands, where they are separated from the submarine and Old Fred (" Lucy in the Sky with Diamonds"). As they prepare to leave, Ringo feels sorry for the lonely Boob, and invites him to join them aboard the submarine. In the Sea of Nothing, the protagonists meet Jeremy Hillary Boob Ph.D., a short and studious creature (" Nowhere Man"). As they operate the submarine, they sing " All Together Now", after which they pass through several regions on their way to Pepperland, including the Sea of Time, where time flows both forwards and backwards (" When I'm Sixty-Four"), the Sea of Science (" Only a Northern Song") and the Sea of Monsters, where Ringo is rescued from monsters after being ejected from the submarine. The four decide to help Old Fred, as they call him, and journey with him back to Pepperland in the submarine. Ringo collects his mates John, George, and Paul. He travels to Liverpool (" Eleanor Rigby"), where he follows a depressed Ringo to "The Pier", a house-like building on the top of a hill, and persuades him to return to Pepperland with him. Fred takes off in the Yellow Submarine (" Yellow Submarine"). In the last minutes before his capture, Pepperland's elderly Lord Mayor sends Young Fred to get help. The Blue Meanies fire projectiles and drop apples (a reference to the Beatles' then-new company Apple Corps) that render Pepperland's residents immobile as statues, and drain the entire countryside of colour. The attack starts with a music-proof glass globe that imprisons the band. The land falls under a surprise attack from the music-hating Blue Meanies, who live beyond the mountains. At the edge of the land is a range of high blue mountains. The titular Yellow Submarine rests on an Aztec-like pyramid on a hill. Pepperland is a cheerful, music-loving paradise under the sea, home to Sgt. Half a century after its release, it is still regarded as a landmark of animation.

Time commented that it "turned into a smash hit, delighting adolescents and aesthetes alike". Pixar co-founder and former chief creative officer John Lasseter has credited the film with generating wider interest in animation as a serious art form, it having been generally considered a children's medium at the time. The film received widespread acclaim from critics and audiences alike, in contrast to the Beatles' previous film venture Magical Mystery Tour. However, aside from composing and performing the songs, the real Beatles participated only in the closing scene of the film, while their cartoon counterparts were voiced by other actors. Initial press reports stated that the Beatles themselves would provide their own character voices. Yellow Submarine (also known as The Beatles: Yellow Submarine) is a 1968 animated jukebox musical comedy adventure film inspired by the music of the Beatles, directed by animation producer George Dunning, and produced by United Artists and King Features Syndicate.
