Born of a flower and growing to only a couple of inches tall, poor Thumbelina is worried she'll never meet someone her own size, until she happens to catch the eye of Prince Cornelius of the Fairies. Just as soon as she finds love, however, it's torn away from her when she is kidnapped by Ms. Toad. Now Thumbelina has to escape Ms. Toad's grasp and search for Prince Cornelius. Luckily, there's a whole city of animals willing to help her.

Mia is a young girl with a knack for getting herself into trouble. One night, when her mother falls asleep while reading "Thumbelina" to her, Mia is magically transformed into the two-inch tall character. As she journey's through "the Unknown Country of Wonderland," Mia will be forced to overcome obstacles that help her grow as a person.
