A Chocobo Saddle is a type of saddle used to ride on a Chocobo after it is tamed using a Gysahl Green. It can be equipped on a tamed Chocobo by right-clicking a tamed Chocobo with the saddle on your hand. Players can then ride on a Chocobo by right-clicking on the Chocobo again, with the saddle in hand. You can also equip your Chocobo with Chocobo Saddle Bags for storage.
