Mako: Island of Secrets (aka. Mako Mermaids) is a spinoff from the show H2O: Just Add Water, and is a television show about born Mermaids who need to go on land and move around on legs and find Zac Blakely a boy who was turned into a merman. Zac is portrayed by Chai Romruen, and the three mermaids are portrayed by Lucy Fry, Ivy Latimer and Amy Ruffle.
Mako: Island of Secrets centers on three mermaids, Sirena, Nixie and Lyla, who are charged with the task of protecting their magical Mako Island from trespassers, only to be thwarted by the arrival of a 16 year old land-dweller Zac – who forms a special connection with the island and is granted a fish-like tail and amazing powers. Threatened by his existence, the mermaid pod are forced to move away, abandoning Sirena, Nixie and Lyla, who in a bid for survival must get legs, venture onto land, and take back Zac’s powers – or risk being outcasts forever.
