Stepping into the flooded dungeon, you need to realise they are not kidding, the dungeon is under water. There are also 2 zarchtons, so remember to bring the Zarchton Harpoon, which you can find at the Treasure Chest in Sleet Island at 07 There are a few areas where you can climb up to breathe, memorise the map as good as you can so you can move as quickly underwater as necessary. Only do one thing at a time to prevent suffocation.
