Sally is an odd little girl. It's not because she dresses as if she's from the Edwardian era or spends most of her time playing with creepy talking dolls. It's because she chases rainbows as if they were butterflies. She believes that if she finds the end of the rainbow then magical things will happen to her-leprechauns will shower her with gold and fairies will grant her every wish. But when she actually does find the end of a rainbow one day, and is given the opportunity to wish for whatever she wants, Sally asks for something that she believes will bring joy to children all over the world. She wishes that it would rain candy forever. She had no idea that her innocent wish would lead to the extinction of all life on earth.
