What blocks can sulfur cubes absorb in Minecraft? Large sulfur cubes can absorb most full-sized solid blocks, and each block type changes how the cube behaves when you hit it. This guide covers every absorbable block, all 12 archetypes, and the effects each one unlocks in the Chaos Cubed update.
- Only large sulfur cubes can absorb blocks — small ones cannot.
- Feed a block by holding it and interacting, dropping it nearby, or using a dispenser.
- There are 12 archetypes in total, each changing bounce, friction, weight, and buoyancy.
- Blocks like TNT and magma unlock special dangerous effects.
- Non-solid, partial, and functional blocks are rejected by sulfur cubes.
- Use shears to safely remove an absorbed block at any time.
How Does Sulfur Cube Block Absorption Work in Minecraft?
The sulfur cube is a passive mob introduced in the Chaos Cubed update. It lives in sulfur caves underground. When a large sulfur cube absorbs a block, it locks into a set of physics traits called an archetype. The cube stops hopping, the block becomes visible inside its body, and it turns into a ball you can hit around.
You can feed a block to a large sulfur cube three ways:
- Hold the block and right-click the cube directly.
- Drop the block on the ground near it — the cube walks toward it.
- Load a dispenser with the block and fire it at the cube.
Once the cube holds a block, it becomes immune to melee hits, projectiles, explosions, fall damage, freezing, and anvil damage. Fire, lava, suffocation, cramming, and the warden’s sonic boom can still kill it. To remove the block safely, use shears on the cube. Killing the cube also drops the block.
If a cube already has a block inside, feeding it a new block swaps them out. The old block drops as an item on the ground.
What Types of Blocks Can Sulfur Cubes NOT Absorb?
Not every block works. Sulfur cubes only accept full-sized solid blocks. They refuse anything partial or functional.
- Non-solid blocks — torches, flowers, redstone dust
- Partial blocks — stairs, slabs, walls, fences
- Transparent blocks — glass, glass panes, leaves
- Functional blocks — crafting tables, furnaces, pistons, observers, chests, dispensers
If you hold a rejected block, the cube ignores you completely and keeps bouncing around.
All 12 Sulfur Cube Archetypes Explained
Each archetype changes five things: knockback resistance, bounciness, ground friction, air drag, and whether the cube floats in water. Here is every archetype and what it does.
Bouncy Archetype — Wood Blocks
Wood blocks turn the sulfur cube into a near-perfect rubber ball. It has the lowest knockback resistance, so it flies fast and far when hit. It also floats in water. This is the most popular archetype for player-built minigames.
Blocks that trigger Bouncy: Planks, logs, stripped logs, wood, stripped wood, block of bamboo, block of stripped bamboo, bamboo mosaic.
Light Archetype — Wool Blocks
Wool makes the cube extremely light with maximum bounciness. It floats and falls slowly, like a beach ball in the air. All 16 wool colors trigger this archetype.
Regular Archetype — Dirt and Common Blocks
Dirt and similar blocks give the cube balanced, default physics. It bounces moderately and floats in water.
Blocks that trigger Regular: Dirt, coarse dirt, rooted dirt, podzol, grass block, sand, gravel, clay, concrete, concrete powder, block of coal, bone block, block of redstone.
Slow Bouncy Archetype — Stone and Terracotta
Stone-type blocks make the cube bouncy but slow and heavy. It sinks in water. This covers most of the common building materials in the game.
Blocks that trigger Slow Bouncy: Stone, cobblestone, andesite, diorite, granite, tuff, blackstone, basalt, obsidian, bricks, terracotta, sulfur, and cinnabar.
Fast Flat Archetype — Organic Blocks
This archetype gives the cube a low bounce and fast lateral movement. It slides quickly across flat surfaces and sinks in water.
Blocks that trigger Fast Flat: Coral blocks, dead coral blocks, sponge, wet sponge, dried kelp block, moss block, pale moss block, pumpkin, melon, hay bale, carved pumpkin, froglights.
Fast Sliding Archetype — Ice Blocks
Ice blocks completely remove bounce and make the cube slide at extreme speed. This is the fastest-moving archetype in the game. It sinks in water.
Blocks that trigger Fast Sliding: Blue ice, packed ice, snow block.
Slow Sliding Archetype — Mushroom Blocks
Mushroom blocks also remove bounce but make the cube slide slowly. It glides without bouncing and sinks in water.
Blocks that trigger Slow Sliding: Brown mushroom block, red mushroom block, mushroom stem, mycelium, nether wart block, warped wart block, shroomlight.
Slow Flat Archetype — Metal and Ore Blocks
Metal blocks make the cube feel like a medicine ball. It is heavy, slow, sinks fast, and has high knockback resistance. It is very hard to knock far.
Blocks that trigger Slow Flat: Block of iron, block of gold, block of raw copper, block of raw gold, block of raw iron, gold ore, nether gold ore, iron ore, copper ore, block of netherite, block of copper, copper bulb, cut copper, chiseled copper.
High Resistance Archetype — Soul Sand and Soul Soil
Soul sand and soul soil make the cube almost impossible to push. It has maximum friction and virtually no bounce. It sits nearly still after being hit, making it useful as an immovable obstacle in builds.
Sticky Archetype — Honeycomb Block
The honeycomb block gives the cube the highest friction of any archetype. It cannot slide or bounce at all. After being hit, it stops almost instantly. It also sinks in water. Get honeycomb from beehives to craft honeycomb blocks.
Explosive Archetype — TNT
TNT is a special case. Once absorbed, the cube can be ignited. After a six-second fuse, it explodes and dies. It does not split into smaller cubes. Shears cannot remove ignited TNT — there is no way to defuse it once it starts. Handle this archetype very carefully.
Hot Archetype — Magma Block
A magma block makes the cube deal contact damage to nearby entities as it bounces around. It floats in water like the regular archetype. This is useful for mob traps and hazard builds. This is the same block found in nether terrain and used in damage-based contraptions.

Java Edition vs Bedrock Edition Differences
A few blocks behave differently between the two editions. These differences are expected to be resolved in Bedrock Edition 26.30 and later updates.
- Resin bricks and block of resin — Fast Flat on Java, Bouncy on older Bedrock (changes to Fast Flat with BE 26.30)
- Ice — Not listed on Java; Fast Sliding on older Bedrock builds
- Slime block and honey block — Not listed on Java; Fast Flat on older Bedrock builds
- Jack o’Lantern — Fast Flat on Java; added to Bedrock with BE 26.30
- Ancient debris — Slow Flat on Java; not currently listed on Bedrock
Stone-type blocks also behave differently based on which experiment mode is active on Bedrock. In the older Drop 2 experiment they use the Regular archetype, while in newer builds they use Slow Bouncy. Check the version you are running before planning builds around stone.
How to Use Sulfur Cube Archetypes in Builds and Farms
Once you understand the archetypes, the sulfur cube becomes a flexible tool. Here are the most practical uses:
- Pinball and minigames — Use the Bouncy archetype with wood blocks. The cube rebounds predictably off walls.
- Obstacle courses — Use ice for a fast sliding puck, or soul sand for a near-immovable blocker.
- Mob traps — A magma block cube deals contact damage as it moves. Pair it with walls to hit mobs automatically.
- Redstone triggers — Hit a cube with a known archetype into a button or tripwire at a calculated distance using a redstone circuit.
- Explosions — A TNT sulfur cube can be used as a moving explosive. Light it and knock it toward your target.
You can carry a large sulfur cube anywhere using a bucket, and it keeps its absorbed block while bucketed. The bucket tooltip even shows which block is inside. This makes it easy to prepare a specific archetype at home and deploy it in your build.
To grow small cubes into large ones faster, feed them slimeballs. You can set up a mob farm to collect slimeballs in bulk. If you want to stop a small cube from growing, feed it a golden dandelion instead.
