Lava Sponge

So when mining or exploring your world you come across lava pools and they are annoying to get rid of because you have to do it with blocks. The lava sponge works like a regular sponge but just for yep lava! To get it you have to travel to the nether where you find it growing on the edges of lava lakes. It grows like glows tone but grows upwards. This allows the player to gather multiple blocks of it all at once. To dry it all you would have to do is use is a cauldron with water in it or a water block source. This means it has the same functionality as an empty bottle. It could be a pale orange color to match the lava color.
