23 parts Complete Erik is back, and he has a plan: to take all the moon ring stones and forge them into one huge stone to reopen the merman chamber on Mako Island.
Sirena, Mimmi and Ondina are put on the case by the mermaid council, and with the help of Zach, Evie, Nixie and Lyla, must stop Erik.
But when they have the stones from their rings stolen, they realise they need help from Mermaids who don't have moon rings... Humans that have transformed into mermaids.
They manage to find some up the coast from where they live: four girls called Cleo, Emma, Rikki and Bella.
Together they work to stop Erik, but they don't know that Erik has been working with Charlotte, Cleo's arch enemy who knows their mermaid secret, and Dr Linda Denman, a scientist who knows all about their mermaid secret too...
Can the mermaids and Zac retrieve all the moon stones and put an end to Eriks' evil plan??
