Timeless Tales: Thumbelina (1990)

Thumbelina grows up to be just as tall as a thumb. Then, the evil toad Gargalong kidnaps her from her happy home. She escapes and moves in with Mrs. Widget the mouse, who tries to marry her to the boring mole, Mr. Budgenot. At the last moment, a kindly swallow carries her off to the land of the Flower Elves, where she marries and lives happily ever after.
