To easily find the locations of all Heart Pieces, go to Fanadi's Palace in Hyrule Castle Town and pay her 10 Rupees for a Love fortune. You will then see an area in the game that will contain a Heart Piece around it, obtainable in some fashion. You can keep paying her to show you other locations, but she will sometimes repeat the same location a few times over.

Turn into the wolf and dig these up, earth worms will appear, scoop them up in an empty bottle and use them as bait for your fishing hook to make fishing extra easy!

[Knil]

There is another Bomb bag capacity upgrade

[Commodore Axilon]

No. No there is not.

[DW]

Axilon is right. there is only the double-sized bags.

[Knil]

I absolutely possitive there is another with no cheats, no secret codes.

[Evahn]

Wouldn't it be easier to just paste the URL, rather than always pasting in huge posts? GAH

And there isn't another bomb bag capacity upgrade.

[Knil]

Yes there is.  I should know I have it.

[Hero Link]

^ How many Normal Bombs can you hold?

[Knil]

If ^ means above person, then 90

[Hero Link]

^ Yes... It means above person. Then how did you get it then?

[bgrugby]

Actually you can hold 180 bombs. But that is if you use all three bomb bags (fully upgraded). In a fully upgraded bag you can hold 60 normal bombs, 30 water bombs, or 20 bombalings.

[DW]

that's a burn. So that means you ahve three bags with normal bombs, but you don't have the bomb bag size upgrade. I have them all, what now? :D

[Hero Link]

Aha! Now i see it... I thought he said that he could hold 90 bombs with one Bomb Bag... xD

[Knil]

No.  It was on the GC version, so it might be different for Wii.  It could hold 90 regular bombs, 45 water bombs, and 30 bomblings.  Now that I think about it can not remember how I got it, but I remember that I did get it.  I check on the Internet and see if I can find it.

[Commodore Axilon]

I have the GC version too, and I think you're full of it.
