Oranges are not the only fruit

As a read this novel and I get to the parts that have the fairy tails in them I find myself questioning what fairy tail it is....starting on page 61, we are introduced to a fairy tail about a "perfect" women and a prince that is looking for a wife with his goose sidekick. When the advisor is sent out to find the perfect wife for this prince he comes across this women who is said to be perfect by the people that live around her. when the advisor goes to great her she says to come back later when she is done with her deadline so sewing. She finally meets with the prince she explains to him that there is no such thing as "perfect" and everyone has flaws. he chops off the gooses head, which I don't understand why. He meets with some man in the forest and I guess he tells the prince to go evil so that the book he wrote will never be wrong. The prince chops of the "perfect" woman's head and then flees up a tree. Walking around he finds a man with oranges. clearly to this author, oranges mean a lot to her that she is bring it up in the fairy tales. What is this fairy tail? Has the author made it up?
