The Explosive Sulfur Cube is one of the coolest new additions in the Minecraft Chaos Cubed update. This dangerous mob variant acts like a walking TNT block, and once you know how to create and trigger one, it opens up insane possibilities for traps, chain explosions, and redstone contraptions. In this guide, I’ll walk you through exactly how to find a Sulfur Cube, turn it explosive, and put it to good use.
| Step | Action |
|---|---|
| 1 | Find a Sulfur Cave underground |
| 2 | Locate a large Sulfur Cube mob |
| 3 | Feed it a TNT block |
| 4 | Activate using fire, redstone, or explosion |
Sulfur Cubes don’t spawn anywhere in the Overworld — you must find a Sulfur Cave biome first.
/locate biome minecraft:sulfur_cavesSulfur Cubes spawn in groups of 2–4 at light level 0. Only large Sulfur Cubes can absorb blocks — small ones (which split from large ones) cannot.
Once you spot a large Sulfur Cube, you have two options:
The bucket method is highly recommended if you want to set up traps above ground or in a specific location.
This is the key step. To create an Explosive Sulfur Cube:
Once absorbed, the cube stops moving and holds the TNT block inside. It also becomes immune to most damage — hitting it just sends it flying instead.
🏆 Achievement Unlocked: Feeding a Sulfur Cube a TNT block unlocks the “Uh Oh” husbandry achievement in Minecraft.
The explosive archetype makes the cube slightly heavier and less bouncy than normal, closest to the regular (football) archetype in terms of physics.

An Explosive Sulfur Cube can be triggered just like regular TNT, plus a few extra ways:
| Activation Method | Works? |
|---|---|
| Flint and Steel | ✅ Yes |
| Fire Charge | ✅ Yes |
| Redstone Signal | ✅ Yes |
| Fire / Lava / Flame Arrow | ✅ Yes |
| Nearby Explosion | ✅ Yes (0.75–3 sec fuse) |
| Campfire / Magma Block contact | ✅ Yes |
Once activated, the fuse timer begins. When triggered by another explosion, the fuse is set to a random 15–60 game ticks (0.75–3 seconds). When it detonates, no small Sulfur Cubes spawn from the explosion.
⚠️ Pro Tip: To remove the TNT from a Sulfur Cube without exploding it, use shears — the TNT pops out as an item and the cube returns to normal.
No. No Sulfur Cube spawns with the explosive archetype naturally. You always need to feed one a TNT block yourself.
No. Only large Sulfur Cubes can absorb blocks, including TNT. Small ones are harmless.
Fire damage still activates the TNT inside even if the cube has Fire Resistance applied to it — so lava and flames are always a trigger.
Yes, but carefully. You can bucket it up before the TNT is activated. Once the fuse is lit, you cannot capture it in a bucket.
