Mako Mermaid

Two young mermaids, Ondina and Mimmi, run away from the Mako Island pod with Sirena to try to turn the merman Zac back into a land boy. But Zac’s connection to Mako is growing stronger. If they fail, they may never break his connection and save Mako for the pod. On the full moon, they attempt to remove his merman powers when his girlfriend Evie comes to the rescue.

When Sirena insists that Mimmi and Ondina remove Evie's new mermaid tail, Mimmi reveals the astonishing range of her powers. She makes Evie morph in the cafe. Zac and Cam must conspire to hide her in the cool room. Zac interrupts Mimmi's spell just in time to stop Evie being discovered as a mermaid. Evie defiantly faces Mimmi and Ondina. They are never to do that to her again.

The mermaids use a moon ring on Zac to investigate his growing connection to Mako. As a result, Zac has visions of an ancient merman chamber on Mako, which he goes to explore, the worried mermaids following. When Ondina steps into the center of the chamber, she vanishes. A curious Erik arrives on Mako and finds her unconscious in the jungle. Ondina and her friends deny anything strange going on.

Erik is keen to get to know more about Ondina. She's not interested in spending time with a land boy. After accidentally transforming into a mermaid in front of Erik, Ondina is devastated. She pleads with Erik to keep the truth about her to himself, however Erik reveals a surprising secret of his own - he is a merman!

Zac and Erik enjoy their first swim together but are shocked to find Evie’s Dad’s boat at Mako, where he has begun taking dive tours. With their home under threat from tourists, Ondina warns Evie to stop her father. When the boat is later damaged, Zac suspects Ondina is the culprit, but then discovers another saboteur is responsible.

Cam is on lifeguard duty when Erik quizzes him about Zac's connection to Mako. Erik is splashed and rushes into the ocean, disappearing. Cam paddles out in search of Erik, only to discover that Erik is a merman. Meanwhile, Sirena and Ondina engage in a contest of mermaid powers, whipping up a dangerous storm over the ocean. Cam gets in trouble for losing Erik, but Erik stages a fake rescue.

Zac goes on a camping trip to Mako with his father, on the night of the full moon. Cam and Erik are invited too. Zac has another vision of the merman chamber, shared by Mimmi, who races to Mako with Ondina. They leave Sirena to mind Evie, who falls under the moon-spell, but she escapes and finds Zac in the chamber, which begins to come alive under the full moon.

Mimmi’s insatiable curiosity leads her to land school, where Erik quizzes her about the symbols he saw in the merman chamber, hoping she knows their meaning. Distracted by Erik, Carly accidentally spills a beaker of water on Mimmi and Rita. They race out and transform into mermaids on the school lawn, cloaking just before anyone sees them. Evie and Zac help them make good their escape.

Ondina reports back to the Mermaid Council but doesn't mention the existence of Erik, or that Evie now has a tail. She's followed home by a young, adoring mermaid, Neppy, who wants to help save Mako. But Neppy is disillusioned when she realises that Ondina lied to the Mermaid Council. Neppy runs away. Zac helps to find her and Neppy realises how hard they've been working to save Mako.

When Evie attempts to retrieve her father’s watch from the marina’s waters, David sees her tail. He’s determined to prove mermaids exist and places cameras in the water, leaving the mermaids trapped on land. Ondina and Erik narrowly escape being caught swimming on camera. Zac and the mermaids have to work out a way of convincing David to give up on his quest.

Mimmi and Sirena prepare a potion that helps the user to look younger. Rita applies some before a school excursion to the Marine Park, accompanied by Dr. Ross, the park's handsome Director. Rita is unaware that Ondina accidentally altered the potion, which now makes her act younger as well. Evie and Zac have to move fast to stop the excursion turning into a disaster.

Mimmi and Sirena try to help David out at the cafe by turning the small crayfish his brother Joe gave him into large crayfish. But they’re interrupted and Mimmi loses her moon ring. Sirena and Mimmi do their best to find it before it’s shipped to China as part of Joe’s export trade. Joe catches Mimmi while she is searching his warehouse. Zac has a vision of her in distress.

On the night of the full moon, Zac is determined to discover the secrets of the merman chamber. Veridia, the head of the Mermaid Council, arrives and uses her power against Zac. She reveals that Zac is a real merman, given up for adoption by none other than Mimmi's mother. Mimmi and Zac are siblings! Mimmi intervenes to save him. Ondina and Rita join Mimmi against Veridia.

Zac struggles to come to terms with the news that he’s a real merman, that he’s adopted and Mimmi is his sister. Mimmi refuses to give up on her newfound brother, but Zac rejects her. A confrontation with some local boys causes Zac to use magic. It looks like he’s about to reveal his secret until Mimmi talks him down. Zac admits to Mimmi he doesn’t know who he is, but the confession is healing.

After Cam absorbs moon pool water, he's thrilled to discover that he has power over water, which gets him a place in the trials for the school swimming team. Zac and Evie try to talk Cam out of competing, but he refuses to listen. When Ondina attempts to remove Cam’s power, she causes water to be uncontrollably attracted to him. Now the race is on for the mermaids.

Ondina sneaks Erik into the grotto to duplicate a pearl he gave her with magic she has learned from Mimmi. But Ondina accidentally turns Erik into a copy of Poseidon and when she attempts to reverse the spell, she turns the two cats into four. Three cats escape from the grotto and the mermaids must find them and change them back, otherwise Erik may be stuck as a cat forever.

Cam realises the shape of the pedestal in the merman chamber is identical to Mako Island, and that five decorative inlays on the pedestal correspond to five rock outcrops on Mako reef. When Erik dives to one of the outcrops and touches it, he vanishes, transported into a sphere of endless water with no way out. Zac and the mermaids help search for Erik.

When Sirena sees an online video that shows a kayaker being lured by a Northern mermaid’s song, she becomes enchanted. She starts to follow David obsessively, even disrupting him at school during an exam. By the time Mimmi works out what has happened, David has already fallen under Sirena’s spell and she is luring him into the moon pool. The mermaids are just in time to prevent disaster.

A surprise birthday party is in the works for Evie, but Zac is so tight-lipped about it that she thinks he’s forgotten. Mimmi tries to cheer Evie up by letting her try on her moon ring. Evie accidentally shrinks herself and falls into an aquarium, which Zac is giving her as a present. The mermaids bring the aquarium to the party without realising that Evie is inside.

Mimmi takes a job at the marine park where she meets Chris, a young man who is desperate to get into a dolphin training program. Meanwhile, Ondina takes a job at the cafe where she has to work with Erik - and deal with customers. Chris and Mimmi's relationship develops and Mimmi helps Chris learn to work with dolphins. Chris gets the gig and has to go away.

On the night of the full moon, Zac and Ondina sneak away to Mako. Veridia has made a deal with Ondina to destroy the chamber. Zac is in the process of activating the chamber when Ondina reveals her plan and Mimmi, Sirena, Evie and Erik arrive. A hologram appears revealing that one more element is needed to complete the activation - the trident, which was lost. The chamber cannot be activated.

Ondina doesn't want to choose between Erik and the pod when the pod returns. To cheer her up, Erik decides to throw a party in the café. But hiring the café is expensive and when Rita's precious pendant disappears, Mimmi falsely accuses Erik of stealing. The party is a success - Cam and Carly even share their first kiss. Mimmi's suspicion makes Ondina realise that the pod will never accept Erik.

Ondina and Mimmi are at odds over Ondina's decision to stay on land. At the marine park, they get into trouble when a dolphin splashes them and a little girl sees them transform into mermaids. Sirena arrives just in time to create a distraction. The adventure reminds the mermaids just how important they are to each other.

Evie has come down with a fever, which results in a soaring room temperature and flaming sneezes. Carly notices the strange phenomena around Evie. She’s concerned that Evie is keeping a secret from her. The mermaids create a cure that backfires, turning Evie’s fever into an icy chill, which freezes Cam when Evie accidentally sneezes on him. Carly discovers the truth.

Erik learns that the trident stone still exists. It’s the missing element needed to activate the merman chamber. Zac retrieves the stone and gives it to the mermaids for safekeeping. Mimmi surprises Erik when he searches the grotto. Erik finds the stone and challenges Mimmi. When Zac comes to Mimmi's aid, Erik uses the stone to draw out Zac’s power, leaving Zac without magic.
