BS The Legend of Zelda: Inishie no Sekiban/Week 1/Overworld part 1

After Sahasrahla explains the situation he gives you the Big Bag. It holds all the items you need for your quest. You will be given your Bag back at the beginning of each new Week.

Once you have the Bag, open your inventory and let the Gold Bee out of its bottle. This is a special bee; it will stay with you and even move between screens with you, and it will not leave you until you get your sword—this is because you are currently defenseless without the bee.

Now head onwards to Dungeon 1, marked on your map.
