Please, I need some help very badly. Right now I'm at the Shrine of Kaddan and I've already defeated the Crystal Cerberus. But, instead of backtracking to a room where the five chests were (the ones with Aquaberrier, Blueberries, Blackberries, and Cooking Materials) I continued on through the dungeon. When I finally returned to the said room, I opened the green chest along with the others. Now, I can't trigger a earthquake in order to crack the east wlal inside the room. What should I do?
