Kill Shrink: The Datapack That Changes Your Size with Every Kill
Minecraft is a game built on consistency—blocks, crafting recipes, and the steady rhythm of survival. But every now and then, a creative datapack comes along that flips a familiar mechanic on its head. Kill Shrink does exactly that by tying your player’s physical size directly to combat and diet. Every time you slay a mob, you shrink a little. Bite into a golden apple, and you grow back. It’s a simple loop that adds a layer of strategic depth to every encounter, and it’s all powered by the versatile Pehkui mod.
What Is Kill Shrink?
Kill Shrink is a datapack designed to work exclusively with the Pehkui mod, a popular tool that allows dynamic resizing of entities in Minecraft. Without Pehkui, this datapack won’t function—so that’s your first step. Once both are installed, the pack introduces a straightforward rule: each kill reduces your player size by a small, fixed amount. Over time, a lengthy caving session or a night of mob farming can leave you noticeably tiny, changing how you navigate the world and interact with blocks.
But you’re not stuck as a miniature adventurer forever. The pack also gives you two ways to regain your stature. Eating a regular golden apple will bump your size back up a bit, offering a reliable—if somewhat expensive—method of control. For a dramatic growth spurt, an enchanted golden apple provides a much larger increase, reflecting its rarity and value. This creates a constant push-and-pull between shrinking through combat and growing through consumption, making every decision about when to fight and when to feast feel meaningful.
How the Shrinking Mechanic Works
The core loop is deceptively simple but surprisingly engaging. Here’s a breakdown of the size changes:
- Killing any mob – Your player shrinks by a tiny fraction. Stack enough kills and you’ll become pocket-sized.
- Eating a golden apple – Restores a moderate amount of size. Useful for maintaining a comfortable height during long adventures.
- Eating an enchanted golden apple – Grants a large size boost, often returning you to or even exceeding your original scale. This makes Notch apples a precious resource for reversing severe shrinkage.
Because the size change is cumulative, you’ll start to notice the effects after just a handful of kills. Your hitbox shrinks along with your visual model, which can make melee combat trickier against taller foes but also lets you slip through one-block gaps that would normally be impassable. This dual-edged nature forces you to think about positioning and engagement range in a whole new light.
Gameplay Impact and Strategy
Kill Shrink doesn’t just alter your appearance—it reshapes how you approach survival. Early on, the shrinking might feel like a nuisance, but soon you’ll discover clever advantages. A tiny player is harder for skeletons to hit and can hide in spaces that mobs can’t reach. You can build compact bases with doorways only you can squeeze through, or create traps that rely on your reduced size. Conversely, being too small can make building and mining awkward, as your reach effectively shortens. This encourages you to balance combat with periodic golden apple consumption, turning a simple food item into a strategic tool.
For modpack creators, Kill Shrink is a lightweight addition that pairs beautifully with other Pehkui-based tweaks or difficulty mods. The author has explicitly allowed its use in modpacks, so you can freely integrate it into your custom experience. If you’re managing multiple mods and datapacks, a launcher like foxygame.net can simplify the process enormously—it lets you download and activate Pehkui and Kill Shrink directly from its interface, keeping everything organized without digging through folders. That kind of convenience is a real time-saver when you’re eager to jump into a world where your size is constantly in flux.
Installation and Compatibility
Getting Kill Shrink up and running requires just a few steps, but the order matters. Since it’s a datapack and not a standalone mod, you’ll need to install Pehkui first. Here’s how:
- Download and install the Pehkui mod for your Minecraft version (Fabric or Forge, depending on your setup).
- Create a new world or open an existing one, then locate the
datapacksfolder inside that world’s save directory. - Place the Kill Shrink datapack file into that folder.
- Load the world and use the
/datapack listcommand to confirm it’s active. You may need to run/reloadif you added it while the world was running.
The pack is designed to be compatible with most other mods and datapacks, as long as they don’t heavily conflict with Pehkui’s size functions. It’s a client-side effect with server-side logic, so it works smoothly in multiplayer—just make sure the server has both Pehkui and the datapack installed. One thing to note: the shrinking effect is permanent until you eat a golden apple, so death won’t reset your size. Plan your apple stockpile accordingly.
Why Kill Shrink Stands Out
What makes this datapack special is its elegant simplicity. There are no complex GUIs, no skill trees, no grinding for levels—just a direct consequence for your actions. It taps into the same satisfaction as a roguelike risk-reward system, where every kill chips away at your physical presence and every golden apple feels like a meaningful recovery. The fact that it’s the creator’s first fully original upload adds a personal touch; it’s a polished little idea executed cleanly.
The lack of visual clutter is also a plus. You won’t find flashy particle effects or intrusive HUD elements. The only sign of the mod at work is your changing size, which you’ll notice as you suddenly fit under half-slabs or struggle to reach a chest on a high shelf. It’s immersive in a way that many overdesigned mods miss.
Final Thoughts
Kill Shrink is a brilliant example of how a single mechanic can refresh the entire Minecraft loop. By linking combat to your character’s scale, it encourages mindful play and resource management without adding bloat. The dependency on Pehkui is a small hurdle, but once you’ve got both installed, the experience is seamless and endlessly entertaining. Whether you’re looking to spice up a solo world or add a quirky twist to a modpack, this datapack delivers a unique flavor of challenge that feels right at home in the blocky universe. Give it a try—just remember to keep a few golden apples handy, or you might find yourself eye-to-eye with a baby zombie.
