The Sunken Gong Piece


One piece of the gong is located in the pool on the eastern edge of the village. This sunken gong piece is obtained by making a special magic stew consisting of one of the black flowers near the waterfall and two of the large orange flowers to the south of the village. Have a villager eat the stew, and then drop them in the pool.
