Unable to think of other ways to make these lifeforms make noise, the Composer looked to the products of its influence, and the underlying mechanics it had for the most part ignored, for inspiration.

Photosynthetic cells, attached to one another to form the shape of a pair of cups (once a single cup but violently torn in two) were floating on the surface of the water, making a distinct gurgling noise and emitting a strange chemical underneath.

And underneath the two cups and the surface of the water, a large amount of cells freely swimming and consuming prokaryotes, avoiding the cups overhead (whom they were responsible for splitting) out of a repulsion for this strange chemical.

In all honesty, the Composer was barely responsible for the latter cells, whom it decided to call “aggressors”. All it had really done was will them away from the Cup while they were consuming it whole. It was intrigued, however, by the method they were being repulsed. It had given the aggressors a repulsion from a chemical, and at the same time made the Cup(s) emit said chemical? The Composer began to ponder this new kind of interaction between its organisms.

So, now some cells were able to remotely repel other cells? That was pretty useless as a defense mechanism, since the Composer would have to have both cells under its influence. And the case with the aggressors was a special case; the Composer wouldn't normally be able to will most attackers away quickly enough. So what other uses might this repulsion have?

Well... does it have to be repulsion? After all, what the chemical actually did to the aggressors was make them want to move away from the chemical's source. What if a chemical made a cell want to move towards its source instead? Not only was repulsion possible, but (in theory) compulsion; a cell could remotely compel another cell towards it as well.

The Composer was becoming more intrigued by the concept every second. When it thought about it, this would be an immensely useful tool to have. Compelling other cells remotely to move? It seemed like an okay function, but... what if the two cells were each part of a larger, multicellular organism? What could be done with that?

It absolutely had to be done. The Composer had more trouble imagining what [i]couldn't[/i] be done with this interaction. Immediately, to set up the first foray into this concept, the Composer willed that the aggressors congregate, much like the Cup had done, and attach themselves to each other, into the shape of a sturdy circle underneath one of the Cups (the other had drifted off), with a circular hole large enough to fit the Cup inside. At the same time, the Composer willed the Cups to extend down to the (shallow) ground, for a sort of anchor.

While the Cups had finished with their changes fairly quickly, the aggressors were evolving to theirs much more slowly, as it was not yet evolutionarily feasible, without a great source of food. Rings of aggressors (horizontally incomplete) finally managed to form around the Cup's anchor, unable to get closer to it due to the strange chemical, and were swimming mainly up and down around the Cup, eating any approaching prokaryotes. These rings attached to another, slowly speeding up the process, and eventually, around the anchored Cup was a disk of aggressors with a Cup-sized hole in them, eating oncoming prokaryotes as they swam up and down the Cup.
