7. The Humans' Law of the Jungle #6
The fairies' realizing that she is shrinking, take her to her own home without realizing that they are the same person thinking that they can get some help. There they find more of the flour (which used to be her brains) with which they proceed to make cookies. Accidentally eating one before dying, the heroine realizes that it restored some of her intelligence and height. By keeping the fairies from eating the freshly made cookies, she ends up eating all of them and going back to normal.
