Minecraft Sulfur Cubes Explained: Finding, Catching, And Modifying The Chaos Update's Best Mob
Update 26.2 added the massive Sulfur Caves biome, bringing along a completely passive and fascinating new mob for clever contraptions and cozy bases alike.
Sulfur Cubes look quite a bit like yellow Slimes, but they have a much more relaxed personality. You'll find them exclusively in the new Sulfur Caves biome. I honestly spend too much time carefully creeping around pitch black tunnels looking for these squishy yellow mobs, and knowing the exact spawn rules takes away a lot of the frustration.
Hunting them down requires a little bit of bravery. They only spawn in areas where the light level sits at absolute zero. They also show up in small groups of two to four, with just a 32 percent chance of appearing.
You'll need to listen closely for a distinct squishy jumping sound. Exploring dark spaces means fending off creepers and skeletons, but knowing exactly what to listen for makes the search feel like a fun scavenger hunt rather than a stressful chore.
Scooping Them Up
Once you spot a group of them, you can skip the hassle of trying to drag them around on a lead.
You can scoop a Sulfur Cube directly into a standard bucket. It drops right into your inventory, which makes moving them back to your base completely painless. This takes the headache out of transporting your new friends across difficult terrain, letting you secure them safely before you start testing out their unique mechanics.
Designing Your Perfect Cube
These mobs happily jump around aimlessly until you introduce a block to their diet. You can hand them a full-sized block directly or simply drop it on the ground nearby.
The cube absorbs the material and instantly changes its physical properties based on what it just ate. It might become incredibly heavy, it might start floating, or it might turn into a tricky hazard. This gives you incredible freedom to customize how they interact with your world, making them perfect for building clever redstone systems or just organizing a bouncy obstacle course.
Fixing Mistakes Safely
If you accidentally feed your cube a block that turns it into a mess, don't worry.
Using a pair of shears safely removes the absorbed block and resets the mob to its standard state. Killing them drops the block, but considering how tricky they are to find, that trade is simply terrible. Shears keep your rare mob safe and return your block instantly, saving you from having to hunt down a replacement cube.
All 12 Cube Archetypes
There are 12 distinct archetypes you can trigger. Each one rewrites the cube's friction, bounciness, and air drag. Knowing exactly what each block does helps you plan out the perfect setup without any guesswork.
Bouncy: Feed them Wood, Planks, Logs, Bamboo, or Resin blocks. This makes the cube incredibly buoyant with a high bounciness stat of 0.9, and it floats perfectly in water.
Explosive: Feed them TNT. The cube can then be ignited to cause an explosion. You'll want to keep this far away from a wooden base.
Fast Flat: Feed them Coral, Sponge, Kelp, Moss, Slime, Honey, Pumpkins, or Melons. The cube bounces less frequently and spends most of its time sliding around at high speeds. It loses the ability to float.
Fast Sliding: Feed them Ice, Blue Ice, Packed Ice, or Snow blocks. This removes the bounce entirely. The cube slides around super fast with minimal friction.
High Resistance: Feed them Soul Sand or Soul Soil. This maxes out the friction modifier. The cube becomes very tough to push and completely stops bouncing.
Hot: Feed them Magma blocks. The cube turns into a hazard that damages any nearby entities it bumps into.
Light: Feed them Wool. The cube's gravity drops significantly. It floats around gently with a massive air drag modifier.
Slow Bouncy: Feed them Stone, Cobblestone, Obsidian, Bricks, Tuff, or Basalt. The cube remains highly bouncy but moves very slowly horizontally.
Slow Flat: Feed them Metal blocks, Ores, Ancient Debris, or Copper. The cube becomes incredibly heavy. It moves slowly and sinks in water.
Slow Sliding: Feed them Mushroom blocks, Mycelium, Wart blocks, or Shroomlight. The bounce ability disappears completely, and the cube slides around the floor at a slow pace.
Sticky: Feed them Honeycomb blocks. This anchors the cube in place. It can't slide or bounce at all, killing all momentum.
Regular: Feed them Dirt, Sand, Gravel, Mud, Concrete Powder, or Bedrock. This is the default state. The cube slides and bounces predictably and floats in water.
