Ocarina of Time

What is the smell item that the woman in the potion shop in the village is looking for and how do I find it?

In Ocarina of Time, you must be adult Link. Make your way to Kakariko Village. Talk to the woman you takes care of the cuccos and she'll give you a pocket egg. Wait for the egg to hatch a pocket cucco. Ok, there is a house next to the stairs. Go into the house and find Talon. Wake him up with the pocket cucco. Then take the pocket cucco back to the woman. She'll give you Cujio (I think I misspelled it). Take him to the Lost Woods where you play Saria's Song to the Skull Kid. You'll see that guy who sits at night in Kakariko Village when your child Link. Take out Cuijo and he'll wake up and ask you to take the Mushroom to the old hag in the potion shop. Take it to her and she'll make a medicine for that guy. Go back to the Lost Woods but the guy won't be there just a Kokiri girl. She'll demand for you to give back the medicine and in return she'll give you the Poacher's Saw. Take the saw to the lead carpenter in Gerudo Valley. You'll need Epona to cross the bridge (she jumps over). The guy will give you a broken Biggoron Sword. Take it to Biggoron on top of Death Mountain to have it fixed but he'll need eye drops from Zora's Domain. Go to Zora's Domain and show King Zora the prescription and he'll give you an eyeball frog that you must take to the scienitist at Lake Hylia. Once you get to Lake Hylia see the scienitist (inside his lab) and show him the eyeball frog. He'll make the eyedrops. Take the eyedrops to Biggoron and then ask him to fix your sword. Wait at least four days and nights (just stay there and play the Sun's Song). Then show him the claim check and he'l give you the Biggoron's Sword.

If is Majora's Mask, you need to beat Woodfall Temple and take the Deku Princess to her father. They'll have a surprise for you. Exit the Deku Royal Chamber and head for the Deku Palace exit. Only once you get to the area where those two Deku guards are turn right and flow the river. You'll come across an opening. Enter it and speak with the butler. You must keep up with him all the while making your way around mazes. When you reach the end he'll give you the Mask of Scents. Go to the Stock Pot Inn and go to the second floor. Go to the last room. Equip the Mask of Scents and go to the bottom bunk thats to your left (you should see a purple fume rising). Put the smell into a bottle and take to the potion shop. Koume or is it Kotake, anyway, she'll make you blue potion.

Doing the whole Biggeron Sword thing might be frustaring but the sword is huge and never breaks so give it a try.

Moved to N64 Zelda.

You get these mushrooms from a guy in the lost woods.
