Sponge is a block which currently has no uses rather than decoration. In the 1.8 update, Sponge will have new behavior and a variant, Wet Sponge.
On June 8 2014, Jeb stated that he is re-adding sponges to survival for 1.8. They still clear water as they did before, though their mechanics are more complex than simply clearing a 5x5x5 area. They still remove water in what appears to be a 5x5x5 area, but it will only remove water if water is touching it, and will remove only water that is connected to the water touching the sponge. This will transform it into a wet sponge, which is darker and drips water particles. Wet sponges make no attempt to keep the cleared area clear of new water, thus getting around the specific bug that required disabling the old sponges in Infdev. The new sponges have undergone a slight retexture. The Sponge Block will be available in Survival Mode, but will not be crafted, and can be found by the methods below:
Ocean monuments have a chance of spawning with a room containing stalactites of wet sponges.
The Elder Guardian drops a wet sponge when killed by a player.
A wet sponge can be dried in a furnace making the sponge reusable. If a bucket is placed in the fuel slot after the fuel is used up, including if the fuel was lava in a bucket, the water will drain into the bucket. This is currently the only way to get the water back.
|May 24, 2009||Sponge suggested on the TIGSource forums.|
|0.0.18a_02||Sponge block added. The sponge was a temporary fix to stop water from flooding until finite water was implemented. It soaked up water in a 5x5x5 area around it. Sponges do not need light to survive, and do not decay (sponges used to decay in the implementation of the 0.0.19a update, but this was changed within 50 minutes of the release). It was also used as yellow for pixel art before yellow wool was introduced.|
|A sponge can be hidden in walls, floors, etc. as a defense against griefers. This can confuse and slow them down when attempting to flood an underground development, leaving more time for them to be caught and stopped.|
|Sponges became non-functional and available only by inventory editing.|
|A sponge can be used as a redstone object for updating blocks. If you place a sponge next to a block that needs to be updated, then remove the sponge, all blocks within a 5x5x5 range will be updated. This can be very useful for redstone builds using the BUD (Block Update Detector) switch.|
|1.8||The sponge is available in Creative Mode, but it doesn't function.|
|1.1||12w07a||Sponge blocks can no longer be used as a redstone tool.|
|June 8, 2014||Jeb tweeted that the ability to erase water blocks will be returned to the sponge. This also shows that they have a new texture. It is also seen that the sponge changes colour once it has absorbed water.|
|1.8||14w25a||Sponges have a new texture (), can absorb water again, and are obtainable in Survival. A sponge turns into a wet sponge when it soaks up water.|
|Pocket Edition Alpha|
|0.8.0||build 2||Added sponges to Creative mode.|
