Japanese Name: Spring Nation
Unlocked By: Defeat the Plant Nation
In the Fontaine, you confront Motochika, and challenge him to gain control of the area. In this battle, there is a river running through the middle of the area. It has two dams which can prevent flow of water, allowing you to cross. These are activated by positioning your Pokémon on the switches.
Unique Area - Gold Mine
The unique area of the Earth Nation is a larger gold mine. This mine allows for finding higher amounts of money and potentially items.
