We should firmly oppose any form of content that involves minors in inappropriate situations. Minors need to be protected and safeguarded, not the subject of such improper 'stories'.
Since the original phrase has inappropriate connotations, in a non - inappropriate context, we could assume that 'forbidden little girls' might refer to something like a group of girls who are not allowed to do certain things (in a non - sexual way), and 'nifty' could just mean interesting, but there are no erotica stories involved. For example, in a story about a group of girls who are forbidden to enter a certain area in a castle, and there are interesting tales about their attempts to find out why.
Another is 'Anne of Green Gables'. Although the focus is mainly on Anne, a girl, there are interactions with boys in the story. It's about her life in a new place, her dreams, and her relationships which are very pure and family - friendly.
Stories like 'The Little Prince' feature a boy's adventures and are full of wonder. It's a great story for kids that has themes of friendship and discovery. Another one could be 'Anne of Green Gables' which focuses on a girl's life, with lessons about family, dreams and growing up.
Well, 'The Wizard of Oz' is a nifty fantastic story. Dorothy's journey through the magical land of Oz, meeting the Scarecrow, Tin Man and Cowardly Lion is full of excitement. Also, 'Beauty and the Beast' is a classic. The idea that true beauty lies within and that love can transform is a great lesson for little girls. And then there's 'Peter Pan', a story about a boy who never grows up and his adventures in Neverland with Wendy and the Lost Boys. It's full of magic and imagination.
One nifty fantastic story could be about a little girl who discovers a magical garden. In this garden, the flowers can talk and they tell her secrets of the world. She has adventures with the little fairies that live there, and together they solve problems like saving the garden from a big storm.
There are many authors who write such stories. J.K. Rowling, for example, has elements in her 'Harry Potter' series that could be considered nifty and fantastic, although it's not specifically about little girls, but still has inspired a lot of similar writing. Another is Roald Dahl. His books like 'Matilda' are about little girls and are full of nifty and strange situations and fantastic adventures.
One reason could be for the sake of a performance, like in a play or a movie where there is a lack of female actors. Another might be for a family's creative or fun idea, such as in a themed party or photo shoot.
Little girls might like stories where boys show kindness and bravery. For example, a story where a boy helps a little girl find her lost pet. The boy could be fearless in the face of difficulties, like climbing a tree to rescue a kitten. This kind of story with positive values can be appealing to little girls.
