Crafting sponges in Minecraft is a valuable skill that can be used to create underwater structures, drain water from areas, and collect experience points. Sponges are relatively easy to craft, and the materials required can be found in most Minecraft worlds.
To craft a sponge in Minecraft, you will need to collect three wet sponges. Wet sponges can be found by killing elder guardians, which spawn in ocean monuments. Once you have collected three wet sponges, you can craft them into a single sponge by placing them in a crafting table in a 3×3 square.
