A small quantity of sand began to displace from its position as something invisible began to move between it.
If anyone had the power to see invisible things, they would have noticed that a white tiny tentacle that didn't have any origin was moving in a particular direction.
After reaching its location, it slithered into the sand in hopes of hiding itself from someone. Having its place secured, it began to listen to the conversation that was happening between two people.
The conversation was happening between a man and a woman, and by being there, it was making a few things sure. The only purpose of the tentacle was to let everything flow as it was supposed to in the first place.
The tentacles leisurely continued to hide there as everything was good for a few moments. Like every good thing, it didn't last forever as well. Sensing a disturbance, it became agitated making the sand around him disturbed as well.
