Pocket Jar Dimensions
- By
Capture a biome inside a jar, shrink down, and step into your own portable pocket world — carry a mini-base in a single inventory slot.
Seal a snapshot of a biome inside a jar, then shrink down and step inside it. Build a secret base, loot a themed guardian's chest, and carry the whole thing around in your inventory.
Features
Portable biome capture — sneak + tap on any biome while holding a jar to seal a snapshot of it.
Shrink & enter — sneak + tap again with a captured jar to shrink down and teleport into its pocket interior.
Themed interiors — Desert, Nether, Jungle, and End biomes each generate a distinct interior, complete with a loot chest and a themed guardian mob.
Truly persistent — anything you build or leave inside stays exactly as you left it, no matter how long the jar sits in your inventory.
How to Use
Get a glass bottle — this is your jar.
Sneak and tap any block while standing in a biome to capture it.
Sneak and tap again (anywhere) to shrink and enter your jar's interior.
Explore, loot the chest, deal with the guardian.
Type !jar exit to return to normal size at the spot you entered from.
Notes
Bedrock doesn't support creating true custom dimensions, so this uses a reserved, out-of-the-way location in the Overworld instead — which is also what makes the "safe no matter what" persistence possible with zero extra save/restore logic.
The jar activates while held rather than being placed as a world block.
