Vessel Cubes
by Knighy
Vessel Cubes is a Forge technology mod for 1.20.1 in which mobs can be captured into portable vessel boxes and carried around.
What it does
Captured mobs are stored inside Vessel Boxes, which are light enough to carry in the inventory, so a captured creature can be moved from place to place. Capture success depends on the kind of mob: pets are always caught, passive mobs have a base chance of 50 percent, and hostile mobs have a base chance of 0 percent. Each mob's chance rises with the lowered health of the target, and upgrading a capture grade improves the odds further.
The mod runs on the client and server together, so the server and every player need it installed. Files are published for Forge only, for Minecraft 1.20.1, and the mod depends on nothing outside the Forge loader. The latest file is 1.0.1 for 1.20.1, released on 2026-06-17. The code is covered by All rights reserved, and the mod is not open source.
Key features
Portable mob capture
Mobs are caught into Vessel Boxes that can be picked up and carried around like other items.
Chance by mob type
Pets are always captured, passive mobs start at 50 percent and hostile mobs start at 0 percent before health is lowered.
Capture grade upgrades
Upgrading the grade of a capture improves the chance of catching a mob, and the rise follows the lowered health of the target.
Required vessel items
Capturing mobs depends on the Vessel Cubes items, so the mechanic does not work without the mod installed.

Use cases
Moving animals between farms
A player can capture a passive animal in one area and release it in another without leading it by hand.
Collecting pets
Pets are caught every time, so a player can carry a companion to a new base or world without the risk of a failed capture.
Who it’s for: Players who want to relocate mobs in survival or creative worlds, and server owners who run a Forge 1.20.1 server with technology mods.
