In Tears of the Kingdom, there is a place called the Pagos Woods Excavation Site. It is a cave in the Faron Region that is inhabited by a variety of foes like Lizalfos, Chuchus and Moblins. A Bubbul Gem, which is obtained from a Bubbul Frog, is one of the treasures that are also found in the cave. These gems are a resource that can be traded for rewards, and create a variety of equipment.
