The bundle item is unobtainable in modern Minecraft versions without the experimental toggle enabled, but it may still be used if obtained from older versions. Bundles were craftable in survival from 20w45a to 21w18a (1.17 snapshots) before this period of unavailability. The crafting recipe was removed in 21w19a because Mojang did "not feel that they are at the quality we want for Part 1 of the Caves & Cliffs release." The recipe was re-added in 1.18 Experimental Snapshot 1 and then removed again in 21w37a. Later on, the bundle is also obtainable in 2 April Fool's snapshots.

Obtaining

Crafting

From 20w45a to 21w18a (1.17 snapshots) and 1.18 Experimental Snapshot 1 to 1.18 experimental snapshot 7, the bundles can be crafted. The crafting recipe for a bundle was two string in the two top corners and rabbit hides in all other slots except the middle.

22w13oneBlockAtATime Enderman Spawning

Warning: April Fools' 

This feature requires the usage of April Fools' versions, often requiring file renaming or file deletion to load. See the help page for information on loading these versions.

Main page: Enderman Holding Invalid Block#22w13oneBlockAtATime Spawning

In the April Fools' version 22w13oneBlockAtATime, Endermen spawn with random blocks and random block states. The bundle cannot be directly spawned because it is an item, not a block. However, the generic_item_block that exists exclusively in this version has a block state for every single item in the game, including the bundle.

This means that the chance for an Enderman spawning with the bundle is very rare. There are 902 equally likely blocks, and generic_item_block is just a 1/902 chance. Then, there are 1105 different values that the generic_item_block can be set to. So, for the bundle, the chance is a 1/902 * 1/1105 = 1/996710 (≈0.0001%) chance of it spawning.

The Experimental Toggle

In the snapshot 22w42a (a 1.19.3 snapshot), the bundle was re-introduced behind an experimental toggle, which is only available on the world generation screen and prevents the world from being loaded in newer versions. However, World Save Insertion may be used to both enable the experimental toggle in old worlds and update it into versions beyond.

23w13a_or_b Votes

Warning: April Fools' 

This feature requires the usage of April Fools' versions, often requiring file renaming or file deletion to load. See the help page for information on loading these versions.

The April Fool's snapshot 23w13a_or_b introduces a plethora of ways to obtain every block and item in the game, including the bundle. These include:

1. The egg_free vote, when applied, will allow chickens to lay any block or item in the game (without NBT)
2. The fish_anything vote, when applied, will allow any item from the creative menu (not the operator tab, with NBT) to be fished (combine with the buff_fishing vote to greatly increase fishing speed)
3. The give_item vote, when applied, will give every online player a random amount of any block or item in the game (without NBT)
4. The replace_items vote, when applied, will replace all items in online players' inventories with any block or item in the game (NBT is preserved)
5. The replace_loot_drop vote, when applied, will replace all loot drops of a random block or item with any block or item in the game (NBT is preserved)
6. The replace_recipe_output vote, when applied, will replace all recipes for the given item with any block or item in the game (NBT is preserved)
7. The villager_gem vote, when applied, will replace all emeralds in all loaded villager's trades with any block or item in the game (without NBT)
8. The vote natural_spawn_replacement can be used to replace the natural spawning of any mob with any other mob in the game, including. Once approved, all mobs as specified by the vote, when spawning from natural spawns, will be replaced with a mob as specified by the vote.
9. The basalt_gen_replace, cobblestone_gen_replace, obsidian_gen_replace, and stone_gen_replace votes, when applied, replace the block of their respective fluid interaction with any block in the game

Uses

Bee Nest Overfilled Bundles

In 20w45a, Bee Nests and Beehives with NBT counted only as one item. By placing more than 1 into a bundle, and upgrading past 20w45a, an overfilled bundle will be created.

Generic Overfilled Bundles

Warning: Downgrading 

This feature uses downgrading which can result in crashes, data loss, or corruption, and requires specific versions. Follow the page instructions carefully.

From 21w06b to 24w20a (present), one can abuse downgrading to overfill bundles. This can be achieved by placing items into the bundle, and then downgrading to a version where those items were not implemented. This allows more items to be inserted into the bundle, creating an overfilled bundle. Then one must update to a version where the items exist again for the overfilling to be complete.

Duplication via Overfilled Bundles

From 21w06b to 1.17.1, overfilled bundles allow for duplication and overstacking are possible. Trying to place items into the bundle by right clicking on the bundle with an item adds more items to the stack, dependent on the amount the bundle is overfilled by and the stack being duplicated. This glitch allows any item added before 1.17.1 to be duplicated and overstacked.

Ghost NBT

From 21w06b to 24w07a, overfilled bundles have a bug when attempting to adding items. If the item is not able to be added to the bundle, and the bundle contains a fill level greater than 64, then the item will be added to the NBT, but with a negative count. Minecraft will always replace the item of any ItemStack with air if the count is less than or equal to zero, but the item's NBT will still remain inside the bundle. This can be combined with written books to create items with very large amounts of data, which are useful for various exploits, such as chunk regeneration or chunk savestating.

Statistics

Main page: Unobtainable Item Statistic

The crafted, picked up, dropped, and used (starting in 21w03a) statistics for bundles are unobtainable without having the bundle, and therefore are also discontinued.
