The bouncy archetype of the Sulfur Cube is the most fun and the most pranks-friendly addition in Chaos Cubed. A cube that copied a slime block becomes a permanent launching pad — mobs, players, and items all bounce off it with vertical lift. In this guide we cover how to set up bouncy sulfur cubes, the best trap designs the pre-release community has already built, and how to defend your base against bouncy-cube ambushes.

 

What does the bouncy archetype do?

 

When a Sulfur Cube absorbs the slime block archetype, it gains the following properties:

 

• Vertical launch on touch. Any entity that lands on the cube is launched 4 blocks straight up.
• Sound trigger. Each bounce emits the slime block sound — useful for Sculk Sensor detection.
• No fall damage. Entities bouncing on the cube don't take fall damage on landing.
• 30-second duration by default. Bouncy cubes lose the archetype unless you "feed" them another slime block.
• Multi-cube chains. Two bouncy cubes placed 4 blocks apart can keep a player bouncing indefinitely.

 

The duration can be extended permanently by using the new Cube Essence to craft a "Permanent Slime Catalyst" — see below.

 

How to set up a bouncy Sulfur Cube

 

The base setup takes 5 minutes:

 

1. Find or breed a Sulfur Cube. Spawn eggs work from creative; on survival, capture one with a name tag from Sulfur Caves.
2. Place a slime block on the floor in your contraption area.
3. Push the cube onto the slime block with a piston facing down, or via name-tag pulling.
4. Wait 1 second. The cube absorbs the archetype — its color turns green-tinted and slime particles emit.
5. Move it to the trap location before the 30-second timer runs out.

 

For a permanent bouncy cube, you'll need:

 

• 1 Sulfur Cube
• 4 Cube Essence (drops from defeated cubes, ~5% rate)
• 1 Slime block
• Crafting table

 

    Place all 4 cube essences around the slime block in the crafting grid to make a "Permanent Slime Catalyst." Feed this to a Sulfur Cube via right-click to make the bouncy archetype permanent.

 

 

Top 5 trap designs

 

1. Wall climber (one cube)

 

    Place a single bouncy Sulfur Cube at the base of a 6-block wall. Mob spawns near the wall now climb it automatically — and so do raid pillagers. Use this to redirect enemy mobs into kill chambers.

 

2. Player launch pad (one cube + redstone)

 

Bouncy cube on a pressure plate trigger:

 

• Step on pressure plate → piston exposes cube
• Player lands on cube → bounces 4 blocks up
• Lands on second exposed slime block → bounces again
• Lands on third slime block → bounces over 9-block barrier into kill chamber

 

This is the foundation for the popular "Mineshaft Tag" PvP mini-game.

 

3. Drop trap (two cubes)

 

Two bouncy cubes facing each other in a vertical tube, 6 blocks apart:

 

• Player or mob enters from top
• Bounces off bottom cube up to top cube
• Bounces off top cube down to bottom cube
• Stuck in infinite bounce loop until you finish the trap (lava, suffocation, kill chamber)

 

4. Crowd disperser (4-cube grid)

 

A 3x3 grid of bouncy cubes (one in center, four corners as bouncy):

 

• Mobs swarming the center get launched in random directions
• Useful for raid defense, mob spawner control, AFK farms

 

5. The Bouncy Maze (creative builds)

 

Bouncy cubes as platforming elements:

 

• Place bouncy cubes at edges of platforms
• Players must time bounces to cross
• Add mid-air rotation with vertical levers
• Combine with magma archetype cubes (damage on touch) for hardcore mode

 

Anti-bouncy defense

 

If players are using bouncy cubes against you, here's how to defend:

 

• Lava walls. Bouncy cubes die when bounced into lava. Spray lava at any incoming cube.
• Magma block floors. Force the cube to land on magma — it loses bouncy archetype to magma archetype.
• Honey block barriers. Honey blocks neutralize the launch effect because their stickiness slows the entity.
• Pistons with cooldown. Push cubes out of bounce position before they can reset.
• TNT minecarts. Quick demolition of established bouncy contraptions.

 

Additional Tips

 

• Bouncy archetype DOESN'T affect cubes themselves. Two bouncy cubes won't infinite-bounce each other; they ignore each other.
• Bouncy cubes work as light sources. They emit light level 5 when active, so you can use them to light up areas.
• Pets bounce too. If you have tamed wolves or cats, keep them away — they get launched and lose target lock.
• The bounce height stacks with player jumps. Jump on a bouncy cube for 6-block lift instead of 4. Useful for parkour servers.
• In creative mode, the Sulfur Cube spawn egg now has a dropdown to select archetype directly. Survival players need physical setup.

 

Conclusion

 

    The bouncy Sulfur Cube is the most fun mechanic added to Minecraft in years and the foundation for an entire new generation of redstone traps and parkour maps. Whether you're building competitive PvP arenas, raid defense, or just a launch pad for your roof garden, the bouncy archetype turns ordinary survival servers into engineering playgrounds.
