Something really bugs me everytime I watch this. Why is the cartoon Giselle wears no earings and the real version of her does , did she magically get them pierced .Also how come shes upside down in the manhole

well, i don't know about the earings, but my reasoning for her being upside down in the manhole is to প্রদর্শনী how opposite their worlds are. I think it's dramatic effect that represents how paralell their worlds are before she even steps inside of it.
