In one of the forest areas in earthrealm after you beat konwuest mode there is a normal treasure chest with koins in it but after you get the koins and turn around you see goro and he quickly dissapers(bad spelling) I have meditated for 8 weeks and have only seen him one other time but he only appears for about 3 seconds.And also in earth realm if you go to the beach area on the other side of were kobra is and talk to the man and woman selling fish they will tell you of a fish that has a jeweled ring inside of it but dosen't tell you were it is.
