Runo shifted in his sleep, still dreaming about his previous home even though some outside noise sneaked in. Someone shouting? 

In his dream, the merman brushed it off as something that one of the humans on the beach were going on about. They could be just as noisy as the whole pod together, but sometimes he really had no idea what they were talking about. It wasn't that he didn't understand human speech, just not all of it. And this voice sounded kind of far away, too, so he didn't really have any way of understanding what was being said very easily. 

Ignoring it for now, the boy continued watching a group of humans playing in the water. His natural camouflaging abilities kept him practically invisible to most eyes, especially those of the creatures on land, so he felt fairly safe in his observation. Xicca had gone off somewhere for the time being, so he was alone for now.
