The Journey Rucksack is an item in Harvest Moon: Tree of Tranquility. This item is required if you want to start a new game as your child. After completing the 5 rainbows and saving the Harvest Goddess, your child will ask you if you believe in fairies. If you answer maybe, your child will claim that he or she saw fairies with pointy hats, which are, obviously, the Harvest Sprites. Your child will then say that your spouse did not believe his or her story, and will then ask you once again if your believe in fairies, to which you should reply 'yes'.
