Sponges are yellow blocks that are only obtainable in creative mode. Sponges are used to stop water from flowing in a certain area. Sponges protect 5x5 zones so that water cannot flood. Some Minecraft members used sponges for yellow pixel art before the addition of yellow wool, and some use it to prevent griefers from flooding homes and mines.
