Sponge crafting recipe

They might need to add new materials to make a recipe. They could add a smaller sponge item in the shape of a brick. And when you interact with water while it is in your hand it will have the same effects as a normal sponge but smaller. The crafting recipe for the sponge block would be 9 of the smaller sponges. The smaller sponges could be a new underwater plant. Or they could grow off a plant. I think this change should come in a future aquatic update part 2 of some sort.
