Years ago, in the Flower Fairy Kingdom a mole stole a huge diamond that was the size of a human’s fist. He hid it in a sealed room hidden in an old tree stump not far from the kingdom. It was sealed with a spell that only allows him to open to the door. But the spell could be broken if the king and queen of the flower fairies open the door. A human woman named Thumbelina who is no bigger than a thumb and the King of the Flower Fairies just got married. They head off for their honeymoon to a nice romantic place, but an amphibian named Mama Frog finds them and informs them that she just found where the mole hid the diamond. The newlywed couple put off their honeymoon to follow her to the sealed door. Since they are the king and queen, they are able to break the spell and open the door. To their surprise they see Mama Frog was telling the truth, but they find out she wants the diamond herself and after rendering them unconscious she gets her spider ally to dispose of them by eating them. Will their fate be sealed? Probably not.
