Princesses can fix it!
(Book)

The castle is crawling with wayward alligators, and the clueless king doesn't know how to fix it. Lila, Margaret, and Harriet have lots of ideas, but their father won't listen! According to him, the Princesses should be focusing on proper pursuits like drawing, jewelry, and music. When the three girls start falling asleep during the day, the King sends the Prince to investigate. He discovers that the three princesses are gathering at night to use their knowledge of the six simple machines to invent an ingenious alligator removal contraption in their secret workshop. A modern, gender-stereotype-smashing reinterpretation of the classic fairy tale, The Twelve Dancing Princesses.
