The only hard part for me was trawling the world wondering where in the hell I could find Carob and Zeio nuts. It's always best to save before breeding a pair of chocobos so you can reset if you don't get the results you want. Also, I have found that wonderful chocobos will ALWAYS be the same gender as each other. The first time I bred a gold one they were all male, and the second time round they were all female. So therefore you will need a black chocobo of the opposite sex, so catch the wonderful one before breeding the black one.
Nah, the Chocobo music's good!It's the darn Chcocobo music that really annoys me. I switch the sound off whenever I'm racing, it's that bad.
