You may be wondering, why in the world would a Chibiusa and Hotaru shrine be named "Drop of a Little Hat"? Well, it actually makes sense. Think about how these two meet in both the anime and manga. In the anime, Chibiusa's hat blows away, and Hotaru is able to catch it before it falls into a lake. In the same vein, Chibiusa also loses her hat in the manga (except it's while she's on a rollercoaster). Chibiusa is the one to find it, but as if destiny had spun a thread, the young pink-haired girl discovers a suffering Hotaru. Without that hat, Chibiusa and Hotaru may never meet. So, with a drop of a little hat, an eternal friendship is born.
