Getting started

Productive Slimes turns slimes into a resource farm. You catch slimes in the wild, breed them into rarer types, keep them in pens that collect their slimeballs, and squeeze those slimeballs into real items.

Install

1. Install Fabric with Fabric API, or NeoForge, for Minecraft 26.3.
2. Put the Productive Slimes jar in your mods folder.
3. Optional: add JEI to look up breeding and squeezing in game, and Jade to see a slime's size and growth by looking at it.

The guide book

Every player gets a Productive Slimes Guide the first time they join. It covers the same steps as this page in a few short pages, and the mod's advancement tab walks you through them in order. See Guide book & advancements.

The loop

1. Find the Slimy Land. It is the only place wild productive slimes live, and the only place with Slime Crystal Ore.
2. Mine Slime Crystal. Almost every block in the mod needs it.
3. Catch slimes with a Slime Jar.
4. Feed and breed them to unlock new types, tier by tier.
5. Put a jarred slime in a Slime Pen. It makes slimeballs on a fixed timer.
6. Press the slimeballs in a Slime Squeezer to get the resource.

Your first farm

1. Find the Slimy Land. Look for bright green grass, sage-colored trees and slime boulders. If you have cheats on:

/locate biome productiveslimes:slimy_land

2. Mine Slime Crystal Ore in the biome's Slimy Stone. You need a stone pickaxe or better.

3. Craft Slime Jars. One recipe gives two.

4. Catch a slime. Right-click a wild slime with an empty jar. Green, Dirt, Stone, Sand and Oak slimes spawn in the biome.

5. Craft a Slime Pen and right-click it with the filled jar.

The pen starts making slimeballs right away. A size 1 slime makes 1 slimeball per batch, and a size 4 slime makes 4. Put the slime's food in the pen's food slot: one item keeps it fed for 4 batches at twice the speed.

6. Craft a Slime Squeezer and put the slimeballs in it.

Each slimeball becomes that slime's resource after 4 seconds. A Stone Slimeball gives 2 Stone, an Iron Slimeball gives an Iron Ingot.
