Goose Girl is a very characteristic fairy tale with numerous well-known elements which can be found in other classic stories for kids. The main character (namely princess) starts her personal quest in high social and economic position just to be defeated by forces from outside (namely her treacherous servant) but with a help of an indisputable authority (namely king, father of her fiancee) and a pinch of magic regains her status and finishes the story in even better position than before.

To become truly evergreen it has to possess some elements which are, with a bit of practice, easily recognizable in other 'classics' as well. Here is a top 10 list of characteristic elements in The Goose Girl with short symbolic interpretations and other not so obvious meanings.
