The Friendship draft only

I think the fox story is all about the friendship and a jealousy. If we go back to the story we can see that fox went jealous when the magpie and the dog were talking happily and always together but one day the fox came to magpie and tried to turn her mind over him and come with him but magpie respond her that ''I will never leave dog. I am his missing eye and he is my wings. So, this shows the friendship.
