Sponge Stone

Adds one block, the Sponge Stone.

It is crafted using 2 stones and 2 sponges.

There is also a brick version.

each has a stair, slab. and wall.

The blocks kind of look like stone, but are a lot more yellow, obvious that they are made from sponge.

This is a dumb idea for a block, and it's exactly why I made it! Hope you all enjoy!
