Trivia

 * The colors for the whistle's and ranks were decided by the colors of the night sky. That is why they go from red, blue, moon etc. Red Whistles were made red so it would be easier to pick them out as beginners as the color is not associated with the night sky but more with early morning. The White Whistles are special because they are not part of the night sky theme.
 * According to Riko, whistles used to be made out of cork but, since cork whistles had problems making sounds at stable volumes when wet, they were eventually replaced with their current, improved designs.
