Sulfur Cube Minecraft 26.2: All 12 Archetypes & How to Get One
The Sulfur Cube is the headline mob of Minecraft 26.2 Chaos Cubed. Here is every one of its 12 archetypes, the block that triggers each, how to capture and grow one, and the mistakes that get cubes killed.
The Sulfur Cube is the strangest mob Mojang has shipped in years, and the first time you corner one in a Sulfur Cave you will probably misjudge it. It looks like a slime and behaves nothing like one: feed it a block and it swallows the thing whole, copies that block's physics, and turns into one of twelve wildly different shapes. That one mechanic — a mob that becomes the block it eats — is what the entire Chaos Cubed update is built around, and it is also why so many early guides get the details wrong.
I have fed cubes about every block I could carry down into the caves, and the pattern that emerges is genuinely clever: the block a Sulfur Cube absorbs decides how it moves. Feed it wool and it floats down like a balloon. Feed it honeycomb and it sticks to the floor like glue. Feed it TNT and — well, you can guess. There are twelve of these states, called archetypes, and each one has its own bounciness, friction, air drag and knockback resistance.
This guide covers all twelve archetypes with the exact blocks that trigger them, how the absorption mechanic actually works, how to capture a cube in a bucket, and how to grow or shrink one on purpose. If you would rather see the cube before you read about it, you can spin all 12 archetypes in 3D on the AlaCraft Sulfur Cube page — it is the fastest way to understand what each state looks like.
What is the Sulfur Cube?
The Sulfur Cube is a passive, jumping, bucketable mob added in Minecraft 26.2 "Chaos Cubed" (Bedrock 26.30). It spawns in the new Sulfur Caves biome, and when a large cube absorbs a full solid block, it copies that block's physics and takes on one of 12 archetypes. It is the second feature drop of 2026, after Tiny Takeover (26.1), and it launches on June 16, 2026 — right now it lives in snapshots.
Think of it as a living physics container. The cube itself does almost nothing interesting until it eats something. The block you feed it is the whole point.
💡 Pro tip: Only large Sulfur Cubes can absorb blocks and be caught in a bucket. Small cubes can do neither — you have to grow them first. More on that below.
A few facts worth pinning down before anything else, because most of the bad advice online comes from mixing these up:
- Large cubes have 8 HP on Java (9 HP on Bedrock until the 26.30 update lands).
- Small cubes have 4 HP.
- They spawn naturally in groups of 2 to 4, at light level 0, only inside Sulfur Caves.
- A large cube killed by damage splits into two small cubes — this is a different thing from natural group spawning, so don't conflate them.
Where to find it: the Sulfur Caves biome
Sulfur Caves are the new underground biome introduced in the same update. You will know one immediately: yellow sulfur blocks, deep-red cinnabar, jagged sulfur spikes, bubbling sulfur springs, and geysers that erupt at random intervals and launch anything standing on them straight up. Underwater pockets contain potent sulfur, a denser variant of the regular block.
One detail that catches people off guard: Sulfur Caves are the first place cave spiders spawn naturally outside of spawners and trial spawners. Bring a sword. The cube is harmless, but its neighbours are not.
⚠️ Warning: Sulfur Cubes spawn at light level 0, so the caves are pitch dark. Light the area to stop new cubes spawning while you work — but don't expect torches to despawn the ones already there.
All 12 archetypes
This is the part every other guide gets slightly wrong. Several popular sites invented marketing names — "Rubber", "Golf", "Heavy", "Magma" — that do not match what the game actually calls these states. The table below uses the canonical names and the real trigger blocks, with the physics values straight from the mechanic.

Two columns do the heavy lifting here. Bounciness is how high the cube rebounds after a hop — Light (1.0) and Bouncy (0.9) are the trampolines, Sticky (0.0) barely leaves the ground. Knockback resistance runs from −2.0 to 0.8, and the negatives are the interesting ones: a value below zero means the cube gets launched further than normal when hit, which is exactly what you want for a cube cannon. Seeing those numbers as bars side by side makes the differences obvious, which is why the interactive viewer on AlaCraft draws each archetype's stats as a meter rather than a number.
How block absorption actually works
When a large Sulfur Cube comes into contact with an absorbable block, it pulls it in. From that moment:
- The cube stops moving, and the absorbed block becomes visible inside its translucent body.
- It turns resistant to damage — melee hits, arrows and explosions (everything except its own primed TNT) no longer hurt it.
- Instead of taking damage, a hit launches the cube like a projectile, and how far it flies is set by its archetype's knockback resistance — which is exactly why the negative values make good cube cannons.
- Its texture and physics swap to match the block it ate.
To get the block back out, use shears on the cube — the absorbed block pops out as a dropped item. A dispenser loaded with shears does the same thing, which is the basis for every automatic cube farm. Killing the cube also drops whatever it was holding.
✅ Note: A Sulfur Cube absorbs mostly full-sized blocks — not everything you place in its path will be eaten. Once it does absorb one, you can see that exact block inside its translucent body, which is a quick way to tell at a glance what archetype a wild cube is carrying.
There is one hard exception, and it is the mistake that ends the most cube-farming sessions:
❌ Mistake: Igniting a TNT-archetype (Explosive) cube and then trying to shear it. Once you light an Explosive cube with flint and steel or Fire Aspect, it primes a 6-second (120-tick) fuse and cannot be sheared, bucketed, or damaged before it detonates. When it blows, it does not split into small cubes — it is simply gone, along with your shears dispenser if it was too close.
Best block to feed your Sulfur Cube
Different builds want different physics. This pairing table is the cheat sheet I wish I'd had on day one — pick the goal, feed the block, get the behaviour.

Catching and growing your cube
Once you have the archetype you want, here is how to keep the cube and shape it:
- Capture it. Hold an empty bucket and click a large cube to get a Bucket of Sulfur Cube. It works exactly like bucketing an axolotl — and like an axolotl, small cubes cannot be bucketed.
- Grow a small cube. Small cubes turn into large ones automatically after 20 minutes. Feed a small cube slimeballs to cut down the remaining growth time (slimeballs also tempt and lead them around).
- Keep a cube small on purpose. Feed it a golden dandelion and it will stop growing entirely. Useful when you want a compact, decorative cube that never reaches absorb-capable size.
Note that this is a baby-style growth timer, not classic two-parent breeding — you are not pairing two cubes, you are aging one up or freezing it in place.
⚠️ Warning: Don't bucket a cube that is mid-absorption. Capture clears its state; you'll lose the block you just fed it and have to start over.
Six common mistakes
❌ Mistake: Feeding a small cube and wondering why nothing happens. Only large cubes absorb. Grow it first.
❌ Mistake: Using the wrong archetype names from other guides. The game calls them Regular, Bouncy, Slow Flat, Fast Flat, Light, Fast Sliding, Slow Sliding, Sticky, High Resistance, Explosive, Hot and Slow Bouncy — not Rubber, Golf or Magma.
❌ Mistake: Assuming the cube eats anything. It absorbs mostly full-sized blocks, and some blocks simply won't be taken — test with a known one like dirt or planks first.
❌ Mistake: Lighting an Explosive cube near your collection system. Once primed, it can't be sheared back and the blast destroys nearby blocks and entities.
❌ Mistake: Hitting a cube to "tame" it. Damage doesn't tame anything — it just splits a large cube into two small ones and resets your work.
❌ Mistake: Searching for cubes in a lit base. They spawn at light level 0 in Sulfur Caves only; a bright room will never produce one.
Quick decision tree
Stuck? Run through these in order:
- Is your cube absorbing blocks? If not → it's a small cube. Grow it (20 min, or feed slimeballs).
- Did the block get ignored? → not every block is absorbable. The cube takes mostly full-sized blocks — try a different one like dirt, planks or wool.
- Can't shear the block back out? → it's a primed Explosive cube. Nothing will work; clear the area.
- Cube keeps getting pushed off your contraption? → wrong archetype. Switch to High Resistance (soul sand) or Slow Sliding for positive knockback resistance.
- Cube won't go in the bucket? → it's still small. Only large cubes are bucketable.
- No cubes spawning at all? → wrong biome or too much light. You need Sulfur Caves at light level 0.
See every archetype before you dig
Reading a stat table is one thing; watching a cube actually bounce is another. The AlaCraft Sulfur Cube page renders an interactive 3D cube you can drag and rotate, with one-click switching between all 12 archetypes and live bars for speed, bounciness, friction and buoyancy. It also lays out the capture flow, the Sulfur Caves biome blocks, the growth cycle and a redstone-automation reference — everything in this article, in a form you can poke at. It is free, works in the browser, and needs no login.
Frequently asked questions
What is the Sulfur Cube in Minecraft?
It is a passive, bucketable jumping mob from the Minecraft 26.2 Chaos Cubed update. It lives in Sulfur Caves and, when a large cube absorbs a full block, it copies that block's physics into one of 12 archetypes.
How many archetypes does the Sulfur Cube have?
Twelve: Regular, Bouncy, Slow Flat, Fast Flat, Light, Fast Sliding, Slow Sliding, Sticky, High Resistance, Explosive, Hot and Slow Bouncy. Each changes bounciness, friction, air drag and knockback resistance.
How do I get a block back out of a Sulfur Cube?
Use shears on it — the absorbed block drops as an item. A dispenser with shears works too. The only exception is a primed Explosive (TNT) cube, which can't be sheared before it detonates.
How do I catch a Sulfur Cube in a bucket?
Hold an empty bucket and click a large cube to get a Bucket of Sulfur Cube. Small cubes can't be bucketed — grow them to full size first.
How do I stop my Sulfur Cube from growing?
Feed it a golden dandelion. It freezes the growth timer so the cube stays small. Slimeballs do the opposite — they speed growth up.
When does the Chaos Cubed update release?
Minecraft Java 26.2 / Bedrock 26.30 launches on June 16, 2026. The Sulfur Cube has been in snapshots since Snapshot 1 (April 7, 2026), with the Explosive archetype and geysers arriving in Snapshot 5 (April 28).
Where do Sulfur Cubes spawn?
Only in the Sulfur Caves biome, at light level 0, in groups of 2 to 4. The biome is full of sulfur and cinnabar blocks, sulfur spikes, springs and geysers — and, for the first time in vanilla, naturally spawning cave spiders.
Chaos Cubed turns a single mob into a box of physics toys, and the only way to really get it is to see each archetype move. Once the snapshot fully clicks for you, head over to the interactive Sulfur Cube guide on AlaCraft, rotate the cube, and flip through all twelve states until you know exactly which block to bring down into the caves.
