A friendly troll with a magic green thumb grows one flower too many for the queen, whose laws require all trolls to be mean ugly and scare humans whenever possible. As a punishment, he is exiled to a world of concrete, where he should live a life of proper trolldom: Manhattan.

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.
