NOw, I am not sure about the 3DS version, but the one I have is for the Wii. (Bought it in the Wii Shop) Alright, so if you go to Kakriko village, on a hill there'll be the Skulltula house. In there is a giant Skultula. If you kill all the skultulas in Hyurle, see the giant Skultula. He'll give you the money bag.
I think the bomb bag is rewarded to you in a chest in dodongos cavern... you must complete that to get the bomb bag, therefore, you will not need bombs until you have gotten to the stage where dodongos cavern is.
Its in the dondongos cavern in death mountain, right next to one of the doors on a ledge in a large treasure box.
after you beat death mountain (as a kid) go to the bombchu bowling alley and play. if the prize is a bombchu bag win and that's how... the prize is random by the way.
From Beetle. He's flying in his hot air balloon, use the whistle on your train to get his his attention, and he'll land near you.
you do not upgrade nuts. only seeds.seeds!:lost forest.turn right. hit the very middle of the target 3 times. a deku sprout will give you a better seed bag.
You get it in the second sub-level you go to as a kid called the Dongos cavern (not sure that's correct spelling) you get it in the room with five or so dongos after you kill them all
You need to get the bomb bag first from the dodongos cavern which is the second dungeon in the game
the bombuchu bag is on goron island
there is no bombachu bag in the temple.
They go in your spoils bag.
a bomb bag
Unless I am very much mistaken, there are no stores that actually sell bomb bags. The reason for this is that you have to first learn how to use Bomb Flowers. This is just another puzzle in the game. However, in Dondongo's Cavern, you will get your own bomb bag -- this is the reward in that dungeon. This is only the second dungeon in Ocarina of Time, so you will have bombs for most of the game. After getting the bomb bag, you will be able to get bombs from the store -- or by simply mining them out of grass.
