Home on the Range, Bringing the World to Life, Piko's Prep, Practice, and Break in the Saddle are quests in Final Fantasy VII Rebirth, taking place in the Grasslands Region and Bill's Ranch during Chapter 2, "A New Journey Begins". In Bill's ranch, Cloud Strife's party wrangled a chocobo named Piko. While learning to ride Piko, the group met Chadley, who assigned them World Intel objectives to help develop more materia for their quest.
Walkthrough[]
Downtime[]
After speaking with Choco Billy and leaving the barn, Chadley will appear. This begins the World Intel objectives, starting with activating a remnawave tower in the bar part of the Activation Intel objectives. Activation Intel marks the other nearby World Intel objectives to make them easier to find. They are activated simply by finding the tower's marked panel, which is either on the foot of the tower or found by further climbing.
Break in the Saddle[]
When finished with Chadley, return to the barn to find Billy, who will have fully prepped Piko to be mounted. Billy gives the party a chocowhistle, enabling Piko to be summoned anywhere on the region. Summoning and mounting Piko then approaching Billy on the outside of the map will lead to the minigame Hustle de Chocobo, a time trial minigame involving racing Piko through checkpoints. Better times in the minigame lead to better rewards, but the minigame is otherwise solely for practice.
World Intel and odd jobs[]
After completing it, Billy will prompt the party about odd jobs, a series of sidequests granting rewards and also helping relationships. A nearby one can be begun involving Chloe named "Flowers from the Hill", while others can be found in the billboard at Kalm, which can be fast traveled to.
Having the chocobo also means the party can now embark on World Intel objectives. These allow the party to develop more materia after completing objectives and earning intel points that can be exchanged with Chadley for more. Chadley also has the Chadley Combat Simulator, where a number of battles can be selected for rewards, including materia, and a battle to obtain the region's 
Summoning Materia.
Titan can be fought to be obtained as a materia, though completing the sanctuaries for the region's Divine Intel first makes the fight easier, as well as improving the materia once obtained. Completing Fiend Intel battles and the Classified Intel battle also unlocks more battles in the Chadley Combat Simulator, including one for the 
Enemy Skill Materia, enabling a variety of unique attacks.
Completing sidequests and World Intel objectives can be very helpful for their rewards. Otherwise, the story is continued with "Through the Swamplands".
