I remember when i got my first choco, I was told that he was trained from a baby to respond to a certain whistle. Well, turns out that everyone uses the same exact whistle. Sometimes i wonder if im riding someone else's bird! And really, how would i know? That aside, how cool would it be if each GC issued its own special whistle? Imagine being with your shellmates, calling all your chocos: you hear a several Serpent whistles, a bunch of Flame whistles and a lone, sad Maelstrom whistle. We have unique salutes, why not whistles!
