Sponge-Like texture below:

#declare Sponge =
material {texture { pigment { rgbf 1 }}
interior {
     media {
       scattering { 1,10 extinction 1.75}
       method 1
       samples 5, 10
          density {
            crackle solid  scale 0.1
            density_map {[0 rgb 0][0.5 rgb 0][0.5 rgb 1][1 rgb 1]}
              }
            }
        media { emission <1,.6,0>}
              }
   }
}
