Cat Quest

Dungeons are scattered all over the map and are in the form of caves and ruins etc. In order to clear a dungeon, you must defeat all of the enemies in it and "cleared" will pop on on the screen when completed. If you have killed all the enemies you see in the dungeon and "cleared" hasn't popped up, that more than likely means there's a hidden passage some where leading to another enemy or so (which is the case in a few dungeons). Dungeons that have not been cleared will have a ? above them. The only one that is slightly hidden and can give you an issue to figure out how to clear it is the Secret Cave which is located on the upper left most snow island. It is located to the top left of the island just behind the mountains as a bush (just look for the ?). To clear it, you must defeat the mimic chest as well as all the ghosts in the middle of the traps (you can't see them but you can see their health bars in the middle of the traps). Once you clear all 52 dungeons, the trophy will pop.
