out what. They were well used to seeing plastic floating along in the water, though not generally a piece of plastic this big. When he was still a young calf, Spirit had taken a bite out of something white that drifted past him in the water and almost choked on a plastic bag as a result. They let the thing float on past them. It got caught by a gust of wind and was blown on to the rocks just out of sight of the beach with all the people on it. The clear floating plastic thing seemed to snag on something sharp and then crumpled as the air leaked out of it. Suddenly there was screaming sound from the direction of the floating thing and Spirit and Dancer glanced back to look at it. ‘ What was that?’ asked Dancer in alarm. ‘ I don’t know’ replied Spirit turning back towards the plastic thing in the water. The airbed sagged and as they looked they realised that a child had started scrabbling around on top of it. ‘ Is that a human?’ asked Dancer. ‘ It looks like a child’ replied Spirit. The human was much smaller than Lucy and Spirit guessed that the child was about half her age. In fact the girl on the airbed was about six years old and had fallen asleep as her brothers had played catch with a ball next to her. Another boy had stolen the ball and her brothers had chased him down the beach to get it back. Unattended, the airbed had floated away from the safety of the shallows, seemingly without any one noticing. Her parents thought she was with her brothers and her brothers thought she was with her parents. No one knew that she was out here at all. The girl started to shout something and although the two dolphins could not understand what she was saying, they could imagine. ‘ She must be shouting for help’ guessed Spirit, overwhelmed with concern for the young girl. Her face was red with tears and hot with fear. However the sound of her screams and cries would not carry far and no one on the beach could hear her over the gentle slosh of waves around them and the noise of the crowds. The airbed had got caught on a shelf of rock a few metres out from the main shoreline, which rose up out of the sea like a small island. The sea was still coming in though and when high tide came, the rocks would be fully submerged. They were slimy with seaweed. The airbed was rapidly losing its air and soon became unable to support the girl’s weight. She clambered off it onto the rocky islet. In doing so the airbed got pushed free of the rocks again and floated away again out of her reach. ‘ Look!’ exclaimed Spirit. ‘The girl’s trapped on those rocks.’ The rocks were so slippery that the girl could not stand upright on them, but instead clung onto them, tears streaming down her face. The two dolphins swam over to where she was and put their heads over the surface of the water in an attempt to whistle encouragement to her. ‘ Do you think that she will get on your back like Lucy does?’ asked Dancer. Instead of being encouraged though, when the girl saw the two dolphins, she shrank back in fear. She’d never seen dolphins before and was too scared and too upset to appreciate that they were friendly and wanted to help her. He realised that even if the girl had wanted to, she wouldn’t have the strength to pull herself up onto his back. ‘ I don’t think there’s any chance of that’ replied Spirit. Just as he spoke, a slightly larger wave came in and washed over the legs and feet of the young girl. It wouldn’t be long before the tide rose higher and larger waves started to batter her. They had to do something. ‘ Well what can we do then?’ asked Dancer anxiously, looking at the scared child a couple of metres away from them on the rock. Spirit shook his head. If only he could reach out to Lucy like she could reach out to him. He could tell Lucy what had happened and she could fetch help. He had no idea how to do that though. ‘ I’d better swim to the beach and find someone who can come back
