After escaping from the circus, to which she was kidnapped as a baby, tiny Thumbelina sets out to find others of her diminutive stature and the place where she belongs. She happens upon Tom Thumb, who was raised by a good normal-sized man. They also meet Zach Loud and his family. But just as they fall in love, Thumbelina is taken prisoner by the terribly sinister Mole King, who wants to make her his bride. Thumbelina is the daughter of King & Queen of Gemworld.
