A lonely widow longing for a child of her own is given a barley seed by a friendly witch. The planted seed grows into a flower, and a tiny girl emerges from inside, no bigger than the old woman's thumb. The old woman names the tiny girl Thumbelina and raises her as her own. Although Thumbelina loves her mother, she craves companionship from someone her own size. One night, the fairy prince Cornelius stumbles upon Thumbelina after hearing her singing. The two take a ride on Cornelius' bumblebee and fall in love. During this ride, Mrs. Toad and her son Grundel are enchanted by Thumbelina's singing. That night, Mrs. Toad kidnaps Thumbelina, desiring her to join their show troupe and marry Grundel. Thumbelina is rescued by Jacquimo, a swallow. Meanwhile, Cornelius learns of her kidnapping and returns to his kingdom, the Vale of the Fairies, to ask his parents to try holding back the winter as long as they can.
