Greens are the entire nutritional meal of a healthy chocobo. All chocobos are herbivores and all chocobos love greens. Chocobos will eat berries, leaves, grass, and sometimes even bark, but greens have the most nutritional value for a Chocobo, besides being absolutely delicious to them. Most chocobos are caught by offering them greens as a sign of friendship, distracting them long enough for you to move in and surround or lasso them. Being docile, they will easily submit to following someone who is leading them by a rope if they have just been given greens.
