has many systems to explore, but one of the most interesting is the Goro Kingdom, an area where you can farm items from animals you recruit.
You can recruit animals to the Goro Kingdom when you meet special creatures in various locations. Once there, Majima can build better friendships with these animals by taking care of them, causing them to produce valuable resources.
Similar to the Golden Balls in , you have to track down many of the potential recruits for Goro Kingdom by exploring your map.
However, you'll meet some Goro Kingdom animals naturally through the main story and quests you've already been following.
Once you progress to a certain point in the story, you'll be taught about the Goro Kingdom and the benefits of gathering more animal recruits.
