After nightfall in a boy's toy room, the Ballerina comes to life and begins to dance. A nearby Jack-in-the-Box finds himself attracted to the Ballerina and begins to peruse her until the neighboring tin soldiers come to life and patrol the room. One of the soldiers (with a broken leg) catches sight of the Ballerina with her leg up and believes her to be disabled, as well. He offers her a rose until he notices her second leg, disappointed. The Ballerina nevertheless accepts his gesture and the two fall in love. The jealous Jack-in-the-Box attacks the Tin Soldier and traps the Ballerina in a glass cup. From under the glass, the Ballerina watches helplessly as the Jack-in-the-Box first tries throwing some blocks at the Tin Soldier in order to knock him out of the window, only to have the hero knock one back at him. This dislodges the Jack-in-the Box's hat and reveals his bald spot, much to the Ballerina's amusement. However, when the Jack-in-the-Box tosses a wooden boat at his opponent, the Tin Soldier falls out of the shop's window, leaving the Ballerina in the grasp of the Jack-in-the-Box. The Tin Soldier returns the following night and fights off the Jack-in-the-Box, who accidentally stumbles into the fireplace, to his death. The Tin Soldier and Ballerina reunite and victoriously proclaim their love.
The Ballerina and Tin Soldier make a brief appearance in the episode "Goofy's Valentine Date". In the show, her dress was incorrectly colored as pink instead of white.
- Like in the original Hans Christian Andersen story, the Ballerina and Tin Soldier were intended to die together in the fire, but the ending changed when it became apparent that the ending would conflict with the music choice for the segment.
- In the original fairy tale, the Ballerina is described as a paper doll. In Fantasia 2000 she seems to be more of porcelain.
