The Adventures of Tom Thumb & Thumbelina begins when 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. He is not only similar to her in size, but is also looking for others like him. 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 and Queen of Gemworld.
