Exit Castle Town through the south gate. Climb the pillar to the left. At the top is a
circle of rocks. Turn into a wolf and dig in the middle. You will drop into a cave filled
with water with two small islands on each side. Kill the enemies for a chest, then knock
down the bee hive for bait. You can catch record breaking Pike and Greengills here and
nearly every other cast can yield a bag of Rupees. It is possible to fill your wallet
here.

After you have filled your third Vessel Of Light and are again in human form, go to the
Howling Stone high up on the cliff by Lake Hylia (the one you could not reach as a wolf).
Behind it is a bombable wall leading into a cave. Bomb the wall and go in. Make sure you
have plenty of Bombs and Lantern Oil. Bomb the walls all around the cave to find enough
Rupees to fill your wallet.

In Kakariko Village, after you have the ability to change into a wolf whenever desired,
and after you can make bomb arrows, turn into a wolf and jump on top of the big building
with the giant bell on top. Shoot the bell with a Bomb Arrow to get a Silver Rupee worth
200 Rupees.

This trick requires the bow combined with bombs. Warp or go to Kakariko Village. At the
top of the Shaman's house is a giant bell. Aim the bow to the inside of the it and shoot.
You can see it clearly with the Hawk Mask that you can buy at Malo's Mart. A kind of light
will fall from the inside and stays on the roof of the house. To get it you must go where
no one can see you and transform into a wolf. At the side of the house there is a
hand-cart. Get over it and Midna will help you jump to the top of the house. There will be
a Silver Rupee worth 200 Rupees.

Go to Lake Hylia to play the little bird's mini-game where you pop the fruit balloons. Get
a perfect score by getting everything at the beginning (you should have 24 points) then
just hit all twenty strawberries to get a Silver Rupee worth 200 Rupees.

There is a dog and bone near the Castle Town west gate. If you throw the bone into the
patch of grass to the right of the doctor's house, the dog will try to get it, but will
instead come back with a Rupee. You can do this as many times as desired. 

Go to any place that has a lot of birds flying around (for example, the bridge over Lake
Hylia) and kill all the birds with your bow and arrow. Once all of them have been killed,
a number of Rupees of different values will fall to the ground.

Once you have the Zora Armor and can dive into deep water, dive into the water in the
center of Zora's throne room. Lift up the small rocks on the bottom and around the area to
find high value Rupees. Four or five rocks have Yellow Rupees (worth ten Green Rupees), a
couple have Blue Rupees (worth five Green Rupees), and one has a Red Rupee (worth twenty
Green Rupees). Once you have collected all of the Rupees, rise to the surface and exit the
throne room. Then, go back into the throne room and dive back in to find the now respawned
Rupees. This is a quick way to fill your wallet.

Go to Death Mountain and a Goron will ask if you want to climb on. Say "Yes",
and continue following the path. A second Goron will asked you the same thing. Say
"Yes" and look to the right. When you arrive, grab the rock, and a Red Rupee
(worth 20 rupees) will appear . Continue following the path and grab the other rocks. Each
one will have a Red Rupee. You can do this as many times as desired.
