How about the sound?

I think that that's intended as well, but I also think they should change it

Confirmed in 1.8-pre2. If you hack in a water/lava source block and place it (or have a wither break water/lava), you will also hear the stone sound.

Still in 1.8-pre3.

Confirmed for 1.8.

Breaking water block causes this sound.

Can confirm for 15w31c.
Confirmed for 15w47c

the particles are intended as the sponge became wet
