On a sunny day at a pebbled beach, three children interact near the water's edge. A boy is lying down, with his upper body seemingly submerged in the pebbles. Another boy and a girl in a Barcelona jersey sit beside him, appearing to be playfully burying or manipulating the pebbles around him. A fourth child sits behind them, slightly out of focus. The sea is calm and stretches to the horizon, with a clear blue sky above.
