Chest Cavity Mod introduces a new storing system into the game and interestingly, it is players’ own bodies. With a crafted Chest Opener, players can burst open their own body. With such ability, players can research, replace and cure themselves off any acute diseases. Furthermore, the prospects to acquire prowess from other entities are made a possibility, as you can gather their organs, replace it within your own body to be as fast as a horse, jump high like a rabbit and witty like enderman. Be careful, however, the procedures to replace your own organs constitute threatening to one’s own life. Interestingly, you can also store normal items into your own body.

Features:
- This tool allows you to access a secondary inventory within your character or other mobs. You can remove and replace organs to gain different abilities.
- Different organs provide various effects. For example, hearts affect your health, lungs affect your breath, ribs affect your hardiness, muscles affect your strength and movement, spleens affect your healing, kidneys maintain your blood, spines let you move, and livers remove toxins.
- Organs come in three tiers: rotten, animal, and human. Rotten organs are half as effective as human organs, while animal organs are three-fourths as effective.
- Organs from other entities can cause organ rejection, leading to negative effects. However, organs that drop as loot are safe to use.
