Chocobo Stables

[Cruise Control]

Ride the green, black or gold chocobo over the hills near Nibelheim (I think that was the place) and dismount in the round area with the waterfall.
How soon on disc 2 can I rent the chocobo stables (Farm or Highwind whichever is sooner), in order to raise a green chocobo?

[Wuggly Blight]
