Bottle Adventure is an interesting glitch that allows you to assign just about every item to the B button as Adult Link. Where Reverse Bottle Adventure writes a bottle item to the "inventory", Bottle Adventure retrieves a "bottle item" from the "inventory".
† Turning the Deku Stick into a Bottle activates the Reverse Bottle Adventure glitch.
|Button Items||Inventory Screen Offsets|
|M. Sword||Hammer||Bombs||Bugs||Slot 15||Slot 2||Slot 18|
In Zelda 64, the contents of a bottle are represented by different item values, meaning that an Empty Bottle and a Red Potion are really two separate items. So to figure out what bottle is equipped (and what bottle to update), the game stores an item slot offset (seen above) for each C button, but not the B button.
The ability to time travel in Ocarina of Time complicates things further. The game records what items you stored on B and the C buttons for both the Child and an Adult versions of Link so that the player does not have to re-equip items after traveling through time. If a bottle is equipped to a C button in one time period, the item value is updated on returning back since the contents of the bottle could have changed in the other time period.
But what happens if a bottle is equipped to the B button when you travel through time? Since an item slot offset does not exist for the B button, Child Link's C-Right button is used instead to determine which inventory slot to restore the B button to when returning back to Adult Link.
Things work very similar to Reverse Bottle Adventure, except we are reading a value to B, rather than writing the item value on B to memory. For example, if putting a Bottle on B with a Bottled Fish on C-Right overwrites the Deku Nut count, going forward in time with a bottle on Adult B with a Bottle Fish on child C-Right will put the value of the Deku Nut count on B.
As an alternative to going back in time, you can instead use the Temple of Time & Light Arrow cutscene to assign an item to B.
The B button is active in any areas the normal sword would be, allowing you to use several items in locations you're not intended to use them, like using Bombs inside the Temple of Time for example.
If you don't have Version 1.0, the item you have on B as an Adult will be reverted back to the Master Sword when you save, unless it's either the Koriki Sword, the Master Sword, the Biggoron Sword/Goron's Knife, or the Broken Sword.
If the trade sequence has been completed, the Biggoron's Sword and Broken Sword will act like the Biggoron's Sword, otherwise they will act like the Goron's Knife and Broken Sword.
The Bow, Slingshot, Bombchus, and Fishing Rod behave differently when putting them on B. See Minigame Items on B for more information.
If you put an Egg on the B button, it will never hatch.
When placing items 0-23 on c-right as a child, the game will look at the corresponding item slot and put whatever value is on that slot onto B. For example, if you have the megaton hammer in your inventory and put the Lens of Truth on c-right, the Hammer will be placed on B. The chart can be seen below.
|item on c-right as child||linked item slot|
|Deku Stick||Deku Stick|
|Deku Nut||Deku Nut|
|Fairy Bow †||Fairy Bow|
|Fire Arrow †||Fire Arrow|
|Din's Fire||Din's Fire|
|Fairy Slingshot||Fairy Slingshot|
|Fairy Ocarina||Fairy Ocarina/Ocarina of Time|
|Ocarina of Time||Bombchus|
|Hookshot †||Ice Arrow|
|Longshot †||Farore's Wind|
|Ice Arrow †||Boomerang|
|Farore's Wind||Lens of Truth|
|Lens of Truth||Megaton Hammer|
|Magic Beans||Light Arrow|
|Megaton Hammer †||Nayru's Love|
|Light Arrow †||Bottle #1|
|Nayru's Love||Bottle #2|
|Empty Bottle||Bottle #3|
|Red Potion||Bottle #4|
|Green Potion||Adult Trade Items|
|Blue Potion||Child Trade Items|
† Unequippable as child
This is a much more useful form of BA that lets you put items on B that are not in your inventory. It can place almost every item on B between 0-50 (the exceptions are Fairy Slingshot, Bombchus, and Fairy Bow). When placing certain bottled items or child trade items on c-right, the game will look at the value of the linked item amount and place an item on B with that value. For example, putting a big poe on c-right with 19 deku seeds will place Nayru's Love on B. Look at the Item Chart for the values of every item.
|item on c-right||linked item amount|
|Fairy||Deku Stick amount|
|Fish||Deku Nut amount|
|Lonlon Milk (full)||Bomb amount|
|Bottled Letter||Arrow amount|
|Blue Fire||Fire Arrow amount †|
|Bug||Din's Fire amount †|
|Big Poe||Deku Seed amount|
|Lonlon Milk (half)||Ocarina amount †|
|Weird Egg||Hookshot/Longshot amount †|
|Cucco||Ice Arrow amount †|
|Zelda's Letter||Farore's Wind amount †|
|Keaton Mask||Boomerang amount †|
|Skull Mask||Lens of Truth amount †|
|Spooky Mask||Magic Beans amount|
|Bunny Hood||Magic Beans popularity ††|
|Bomb Bag (holds 20)†††||Water Temple Small Keys|
† Unused Value.
†† This is how many Magic Beans you've ever bought from the Bean seller in Zora's River. For example, if the value is set to 6, he will charge you 70 rupees for a bean. Any values higher than 9 cause him to stop selling beans.
††† It is possible to equip this item due to an Upgrade Oddity.
It is possible to place an item on B depending what items you have in your equipment screen with the Goron Mask and Zora Mask. See this page for more details.
