Did you even give it a second thought? Or did you just have them all named 'Boco'?

While breeding, I named mine by "rank." My GOOD Chococobo was named GOOD, my GREAT named GREAT, and my WONDERFUL named WONDER (it wouldn't all fit). When it came to the specials, I named them by what they can cross (up until GOLD). My Blue Chocobo was name RIVER, my Green one named ROCK, and my Black one named SAND. Then I named my first Ocean Chocobo GOLD. Eventually, I'll get bored and decide to breed more Ocean Chococbos, and then I'll start naming them wacky stuff, like WINNER .
