Addon: Chest Cavity PE
Chest Cavity PE is an unofficial Bedrock port of the organ-system concept created by TigerOfTroy. Players and many creatures receive internal cavity inventories filled with organs rather than being represented only by ordinary health points.


Author: Pronk; original concept by TigerOfTroy

To open the player's own body, look downward and use a long press. The interface exposes separate slots that can be inspected and modified. Cavity screens for Iron Golems, Slimes, Zombies, Chickens, Villagers, Cows and Pigs demonstrate how different creatures carry different internal parts.


A heart taken from an animal or monster can replace the player's original heart. Installing it grants the ability associated with the donor, allowing creature traits to become part of the character build.

Placing a heart is not enough to trigger its power immediately. Sneak three times in succession to prepare the installed ability. This creates a deliberate activation step and reduces accidental use.


The pack changes the normal approach to survival by turning creature encounters into a source of biological upgrades. Because it is an unofficial port with complex interfaces, testing it in a new world before using an important save is recommended.
How to install the add-on
Download the .mcaddon or .mcpack file, open it with Minecraft and wait for the import to finish. Then enable the resource and behavior packs in the world settings. If the add-on requires experiments, turn them on before launching the world.
