Bomb Bag

The Bomb Bag is the case in which Link carries his supply of Bombs. In Ocarina of Time it is said that the Bomb Bag is made from the stomach lining of a Dodongo. It is often possible in Zelda games to acquire larger Bomb Bags as you progress.

Ocarina of Time
In Ocarina of Time you can get two upgrades: one as a prize in the Bombchu Bowling Game and one from stopping Hot Rodder Goron's wild rolling around Goron City's 3rd floor.

Majora's Mask
In Majora's Mask there is the regular Bomb Bag and the Bigger Bomb Bag. You can obtain the Bomb Bag by returning to normal, then going to the 3rd shop in West Clock Town. They will have the Bomb Bag in stock, and you can carry Bombchu and Bombs in it. The Bigger Bomb Bag is obtained by going to the Curiosity Shop on Night of the Final Day, around 10:00 p.m. . They will have the Bigger Bomb Bag there, OR you can save the old lady from Sakon the thief in North Clock Town at Night of the First Day, around 12:00 p.m. She says that they will then put Bigger Bomb Bags in stock at the Bomb Shop the next day, but the bag will be there right away.. This also allows you to get the All-Night Mask from the Curiosity Shop at 12:00 p.m. Night of the Final Day, for 500 Rupees. Then, you can get the Biggest Bomb Bag from the Deku Merchant in the Goron Village at Snowhead for 200 rupees and your Bigger Bomb Bag.

The Wind Waker
In The Wind Waker, the bomb bag is not actually shown as a physical item, however it is still possible to upgrade the number of Bombs Link can carry by visiting the Great Fairies. Initially it can hold 30 bombs, with increases to 60, then 99.

The Minish Cap
In The Minish Cap, the bomb bag can firstly be collected from a Forest Picori named Belari. Later on in the game, Link can find a Great Mayfly Fairy in Mount Crenel who will provide him with a bigger bomb bag. Also, fusing Kinstones later on with Belari will cause a treasure chest to appear in Wind Ruins which provides Link with an even bigger bomb bag.

Twilight Princess
Bomb Bags work a bit differently in Twilight Princess than they do in other games. A Bomb Bag with bombs can first be obtained from Barnes in Kakariko Village as part of a special package once he restocks his shop. There are three types of bombs which can be put into it - regular Bombs, Water Bombs, and Bomblings - and the maximum number depends on the type of bomb, being 30, 15, and 10 of each type respectively. Furthermore, only one type of bomb can be used in a bag at a time. To cope with this handicap, two more Bomb Bags can be obtained: one by using Bomb Arrows to clear away rubble downriver of Iza's boat rental, and the other by using Water Bombs to destroy the Molten Shard used to thaw out the throne room of Zora's Domain.

If Link scores 25 or more points on Iza's river rapid ride game, she will give him the Big Bomb Bag, which doubles the carrying capacity of all his bags, allowing them to hold up to 60 regular Bombs, 30 Water Bombs, or 20 Bomblings.
