he answered.
“See you tomorrow, Sophie.” Antonia waved at her other best friend, who waved a sketch book back. Sophie was mad about art and her latest project was painting pictures of the cats that roamed around Sandy Bay.
“Ooh, look at the lovebirds,” called Lauren nastily, as Antonia and Cai ran from the building together.
Antonia ignored the comment, knowing that it was the best way to deal with Lauren.
“Spirit, I hear your call,” she murmured as her dolphin charm thrashed its tail and then began to whistle. Spirit was the leader of a dolphin pod and he was responsible for calling the Silver Dolphins.
Cai’s badge was whistling too and the combined noise was ear-splitting. Nervously, Antonia glanced up at the parents waiting at the school gates, but only a Silver Dolphin could hear the dolphin’s call and no one looked their way as they weaved between them.
“Which beach?” panted Cai.
“Sandy Bay’s nearest,” said Antonia, her fingers still curled round her dolphin charm. Its tiny tail flicked against her palm, urging her into the sea. She and Cai ran neck and neck down the street, only stopping at the promenade to pull off their shoes and socks. Antonia was first to jump down on to the beach. Her feet sunk into the soft white sand and it trickled through her toes as she ran to the rocks.
“This’ll do,” she said, dumping her things against a large boulder before stepping across the rocks to the sea. Cai hobbled slowly behind. It was only the second time he’d answered the dolphin’s call and his feet weren’t used to walking across slippery rocks encrusted with knobbly barnacles. Antonia hesitated. Normally, she would answer Spirit’s call as fast as possible. But she had a strong sense that this time it wasn’t urgent and wondered if she should wait for Cai.
“You go on,” called Cai.
Antonia was grateful to him for letting her go ahead. What if her feeling was wrong and Spirit’s call for help was life or death? Splashing into the water, Antonia concentrated on believing she could swim like a dolphin. The moment the sea reached her waist, she lunged forward. Instantly her legs felt as if they had joined together. Antonia whistled delightedly as she swam out to sea; legs flicking like a tail and arms paddling the water like flippers. She swam clear of the bay and into the open sea before she felt vibrations in the water. Something was coming towards her.
“Spirit?” she whistled.
“Silver Dolphin,” he answered. “You came quickly.”
Moments later, Spirit appeared and swam straight up to Antonia to rub his nose against hers. Spirit was a magnificent dolphin with a yellow blaze stretching along his silver flank and dark stripes running from eyes to mouth and chin to flippers. Shyly, Antonia rubbed his nose back.
“What’s my task today?” she asked.
Spirit sighed.
“This afternoon a boat anchored up near the cliffs. Two people were diving from it. They seemed to be bringing up things from the seabed. I couldn’t see what. When they’d finished they had a clear out and threw their rubbish overboard. It’s made a terrible mess.”
“Lucky you saw them,” said Antonia. Rubbish was a serious problem for sea life and could cause animals to choke or drown.
Cai arrived, panting slightly and with a determined look on his face. “I made it,” he said.
“Silver Dolphin,” clicked Spirit, swimming forward to rub Cai’s nose with his own. “Thank you for answering my call.”
Cai blushed in awe.
“It’s litter-picking today,” clicked Spirit. “Follow me and I’ll show you where.”
Spirit set off at a cracking pace, until he noticed Cai lagging behind and slowed down.
“You’ll have to teach me how to do the arms,” Cai whispered to Antonia. Cai hadn’t learned how to use his arms like flippers and was still doing breaststroke with them.
“It’s easy once you get the hang of it,” Antonia clicked back. Becoming a Silver Dolphin had felt natural for her, but there was a lot to learn. Antonia also knew there were still things that she hadn’t discovered.
Spirit was heading for the cliffs between Sandy Bay and Gull Bay. Antonia gasped when she saw the mess the boat trippers had left behind. It looked like they’d emptied a wheelie bin straight into the sea. There were empty tins, cardboard cartons and an enormous amount of plastic waste; all things that could injure sea life.
“It’s disgusting!” Cai exclaimed. “Why do people think it’s OK to dump stuff like this?”
“Often it’s because they’re just lazy,” said Antonia.
“And ignorant,” clicked Spirit. “Many people don’t realise the harm their actions cause.”
Spirit had to get back to his pod, so he left Antonia and Cai hard at work. Cai was lucky enough to find an enormous clear plastic bag that they used to collect the litter in.
“Lucky on two counts,” said Antonia. “A dolphin could suffocate in that.” She shuddered, thinking of her dolphin friend Bubbles, Spirit’s inquisitive son. What if Bubbles had got his head stuck in the bag?
“I wonder what the people were diving for?” asked Cai. “This isn’t just picnic waste—look.” He held up a soggy sheet of plastic with a label stuck to one side. “The Stretchy Strap, secures your torch to your arm for hands-free diving. And there’s this,” Cai reached out and pulled another plastic bag towards him. “Dive Bag, made from heavy-duty poly…” Cai squinted at the label. “I can’t read that bit, but it goes on to say that the bag is perfect for bringing diving finds to the surface.”
“Weird,” Antonia agreed. “It’s not like there are any wrecked boats around here. I wonder what they were collecting.”
A light breeze came from nowhere, ruffling the sea’s surface and sweeping Antonia’s hair across her face. She pushed it away, shivering as a bad feeling suddenly came over her.
“What’s up?” asked Cai. “You’re whiter than a ghost.”
“Nothing.” Antonia shook the feeling away.
“Oh!” she exclaimed.
“What?” asked Cai.
“Vibrations.” Antonia grinned, suddenly feeling much happier. “Someone’s swimming this way and I bet I know who.”
A few seconds later, two dolphins arrived. “Bubbles!” laughed Antonia, as her favourite dolphin surfaced beside her.
“Flipper Feet!” squeaked Bubbles. Then, whipping up the sea with his flippers, he clicked, “Water fight!”
Antonia, Bubbles and Cai splashed water at each other until Antonia remembered the second dolphin hovering
