Under Dwell Level H0, Treasure Hunt, is part of the “Home Side Quest“. To unlock this quest, you must complete the Gate Keeper’s treasure hunt. He gives you a clue as to where each of the three items are located. We have labeled the image below.
Go to each level and drop the item safely into the boat. You must pass the level in order to fully obtain the item. Then return each item to the Gate Keeper to gain access to the quest.
