H2O - Mermaid Adventures

To help their friend Cleo get hired (as a volunteer) at the Dolphin City Oceanic Centre, Rikki, Emma and Lewis take her out free-diving off Mako Island, to see underwater wildlife in person! But when their motorboat's engine fails, they have to spend the night on the island: that night, when Rikki, Emma and Cleo are exploring the island, they fall into a mysterious cave.

Little Elliot gets his big sister Emma to enter the Grand Sand Sculpture contest with him. Meanwhile Cleo's day starts badly at the Oceanic Center: Mr. Lambert puts her in charge of the new intern - Miriam, the Mayor's daughter and high school pest! Miriam lives up to her reputation, and submits Cleo to a series of capricious outbursts.

During a scientific experiment conducted by Lewis out at sea, the three mermaids find a wooden statue of a white mermaid on the seafloor! Lewis discovers it's the figurehead of a famous pirate galleon, the White Mermaid, which sank at sea without a trace! Rikki and Emma are thrilled, while Cleo is preoccupied by something else.

Emma's in a dilemma: handsome Byron has invited her to his birthday party on his uncle's yacht. Her girlfriends tell her it's no place for someone who transforms into a mermaid at the slightest drop of water. But Emma willfully goes along. Afraid she'll do something silly, her girlfriends and Lewis join the party.

A grand holiday resort on Mako Island? Its idyllic slopes covered with concrete and the volcanic lake inside the mountain, where the mermaids first transformed, converted into a swimming pool? Only Zane's father could have dreamed up such a development. But Emma, Cleo and Rikki aren't going to let this happen!

Emma loses her mermaid nature and her powers after touching some mysterious blue seaweed. Remembering what it's like being "normal" - she used to be a passionate swimmer - she rejoins the synchronized swimming team, which is preparing a show for the Summer Solstice Festival.

More and more plastic bags are polluting Dolphin City Bay, and the turtles mistake the bags for sea-sponges and suffocate on them. Our three mermaids, alerted by their friend Teddy the turtle, tackle the problem. After some unsuccessful attempts, they and Lewis decide to use stronger methods to stir up public opinion.

In the aftermath of a violent storm, Dolphin City looks like a new Bermuda Triangle: boats mysteriously break down or sink in the bay. At the sight of hordes of journalists, the girls investigate, with Lewis' help. They find out that a lightning bolt from the storm has activated mysterious crystals whose magnetic field disrupts navigation equipment.

When Emma, Cleo and Rikki find out two superstars - Brad Patinson and Scarlett Belladonna - are shooting a film in Dolphin City, directed by the famous Martin Fabiola, they try anything to get on the set. Luckily Zane has been hired by the production! Only Rikki prefers to approach the stars in her own way - underwater of course!

Murray and Burke are inconsolable: their pal Danny the octopus has disappeared! By chance, Cleo finds out that he's in fact been captured by the Oceanic Center, who are conducting scientific research. Murray puts pressure on the mermaids to get Danny out of there and bring him back to the sea. But Danny doesn't want to go home.

Why has a whale calf run aground on an isolated beach near Dolphin City? And what's causing the girls' migraines? Does it have anything to do with the dolphin twins' bizarre sickness? During their investigations the mermaids come across a strange fishing boat using illegal technology: an extremely low-frequency military radar device.

Burke the hammerhead shark has broken a tooth. To sooth the pain, he has to come up for air at the surface regularly: but in so doing, he involuntarily shows his fin. Before long a panic wave runs through the citizens of Dolphin City, who think they've got a dangerous shark on their hands.

Rikki has to make up for her mistakes! Convinced that her father's new girlfriend, Cathy, is dishonest, Rikki sabotages the dinner in which her father tried to ask Cathy for her hand in marriage. To bring the estranged sweethearts back together, Rikki absolutely has to recover the lost engagement ring, which fell into the sea during that tumultuous dinner.

Worrying events agitate the little underwater community of the Bay: clownfish are inexplicably disappearing one after another. The mermaids try to get to the bottom of this mystery, to find their friend Ziggy, a little clownfish who's among those missing.

Cleo is down in the dumps: she might lose her job at the Oceanic Center, since she said she's allergic to water, to avoid getting wet in front of Mr. Lambert. Swimming out at sea, she wanders into a strange stone circle - suddenly she wishes she could forget all about this mermaid business. Her wish comes true.

It's Valentines Day! Lewis and Abby spend the day together like sweethearts. Cleo goes crazy with jealousy. She finds out that Lewis has promised to tell Abby a huge secret. And what if - blinded by love - Lewis were to betray Cleo and her friends, by revealing that they are mermaids?! Emma, Cleo and Rikki have to get to the bottom of this.

The inhabitants of the Bay are overwhelmed: one of the dolphin twins, Robby, has disappeared, captured by an unknown speedboat. Bernie calls on our three mermaids for help: the girls were walking around Dolphin City, which is all decked out for the carnival. But why would anyone kidnap a dolphin?

In her sleep Cleo creates huge spheres of water that float through the air in Dolphin City, causing chaos. This strange phenomenon is caused by her worries about her Dad, who is on a mission out at sea. And what if Cleo's worries are real? What if her Dad really has fallen into the hands of dangerous outlaws involved in illegal fishing?

The girls find some turtle eggs on Dolphin City beach: they are too fragile to move, so they take turns watching over them till they hatch. But that's not counting with Miriam and Zane - who are having a beach party! Meanwhile, underwater, Bernie, cannot bear all the noise and disruption his neighbors are making, and decides to leave his cave and go and stay elsewhere for a bit of a rest.

The White Mermaid is in danger! Her sanctuary, the sunken galleon of Edward the Cruel, is about to be discovered by Stanley Finch, the famous explorer. The girls decide to stop him, and make his boat take another course, towards the sinister underwater stone circle.

After being carried by a current into the underwater stone circle, Rikki is victim of a terrible spell: she cannot turn back into a human! To break the spell, she has to wait for the full moon -in three days' time!

The Bay prepares for a great excitement: there's soon to be the first great robotics competition organized by the Dolphin City University. The events will take place underwater, and Lewis wants badly to win first prize: enrolment in the Science Faculty! Unfortunately, Zane is also participating, and true to form, can only do it by cheating.

Emma's kid brother Elliott happened to see Rikki's mermaid tail in the water! He starts telling everyone he's seen a sea monster. To cover up, the girls and Lewis start building a fake monster, to make people think it was all a hoax. But it's too late - the whole town's out looking for the famous "Dolphin City Monster".

The Vandals are carrying out a nasty plan: they have enlisted a terrible horde of stinging jellyfish to sow terror in the Bay. But the mermaids aren't able to respond: Rikki grounded, wrongly accused of calling in a fire alarm at school, and Cleo has to help care for swimmers stung by the jellies.

A lunar eclipse makes Cleo lose her power! Lewis tries to get it back using scientific methods, but he runs into a lot of trouble! Meanwhile, Teddy the kid turtle has got into trouble with Bernie and the other animals in the Bay after playing too many practical jokes.
