A sponge, absorbs water. Turns darker when water is absorbed. Burns when exposed to fire or at temperatures above 2450. Water can be released under high pressure or when SPNG is burnt with fire.

When sponge absorbs salt water, it may drop SALT. When absorbing BUBW, it releases CO2. When absorbing PSTE, the PSTE gets turned into CLST.
