Alright, then! This is the petra-cola (rocky dweller)

It works like this:
The petra-cola consists of only three types of cells. Originally, the creature was only a bunch of purple translucent single-celled organisms which bonded together for protection. These cells consumed germanium. Eventually, these groups began to be deposited on beaches and were exposed to harsh radiation. The outside layers died, forming a tough shell around the blob. After many years, another type of cell came into the group. It was a small cell which consumed selenium and excreted germanium at a very efficient rate. When these cells bonded, they were able to expand the groups to larger proportions, due to the more effective energy intake. Eventually, another type of cell moved in, one that also consumed germanium. These cells had simple cilia which always pumped in one direction. These cells oriented themselves so that they pushed dirt into the interior of the organism. This caused the organism to expand to an even greater size.
Currently, the organism is so simple, it can barely hold itself together. Thus, when the cilia cells on the bottom begin to dig, the organism will follow gravity and slosh into the hole. However, with the increased efficiency, the organism is able to grow as fast as it falls, making it tunnel slowly into the ground.
later, the various cells began to form a column, in which the cilia and selenium-consuming cells would occupy. The cilia would pass the dirt past the selenium cells, who would digest what they needed and pass the waste to the rest of the organism. Each organism would normall have around five of these columns.
When the organism gets around six feet long, the relatively thin column it has created can no longer support such a massive entity. When this happens, it spits out "spores" which contain varying amounts of all three organisms. These spores roll down the sides of the petra-cola and start up their own colonies. Shortly after releasing spores, the organism dies.
On the surface, the petra-cola appears to be nothing more than a mound of lightly colored dirt, from which small pieces of sand slowly emerge
