Smog monster
this one actual comes from my favorite Godzilla movie and that is Godzilla vs the smog monster. the film is about an alien crash land on the earth and absorb the population of japan forming into the smog monster. it is up to Godzilla to decent the foe and clean up the mess. the piece is from where the smog monster is in the water soaking up the population and growing. you can see the water is slowly be turning into the body liquid of the smog monster.
