When you first enter a chocobo forest (does not mater which one) you well meet a little boy named Chocoboy. He'll explain to you about the whole Chocobo deal. He will offer you a ChocoWhis and teach you how to use if for 1000 Gil. Now you must have this Whis in order for the Chocobos to come for you so you might as well pay. This Whis is the tool for locating baby chocobos (chicobos) in the forests. The ChocoWhis has two modes on using it: "ChocoSonar" and "ChocoZiner". "ChocoSonar" is used to sniff out the Chicobos location. The "ChocoSonar" will produce a soft ping as you seach an area and it will change to a hight fast-pitch that is loud if you standing in the right spot for a chocobo to fall down. When that happens use the "ChocoZiner" mode. Blowing on this will send a Chicobo to drop from above or go into hiding if you're on the right spot. If you are not in the right spot, the Chicobo will steal your ChocoWhis and you'll have to buy an addition one from the Chocoboy for 700 Gil. So be careful alright?
