I'm in the dungeon, I rolled into the water, I've budged the 2 Watchdrones.....I can see the Flying Ing key thing I need to kill to get the key, but I can't get to it. It's behind a mesh wall. My Trilogy guide says "Destroy the Flying Ing Cache in the room beyond for a Sky Temple key". The room beyond?? I'm already in the dungeon? Any help??
