I'm Henrietta and there's a strange and ominous scuffling noise under my bed. I can tell it's not a crocodile and I'm sure it's not a rhino and it absolutely can't be a monster because monsters lurk in dark misty lakes, not under beds. So who could it be? One thing I do know is it's time to make some discoveries. When Henrietta finds Mabel May Hissop sleeping in her sock, she discovers not only a small fairy with a big problem, but also a big way to explore the small things in life.
