Mako Mermaids: An H2O Adventure

During a full moon, a land boy named Zac falls into the Moon Pool, and the power of the moon transforms him into a merman.

Sirena, Lyla and Nixie must turn Zac back into a land boy. Using Sirena's Moon Ring, they give themselves legs and walk on land to begin their task.

Sirena, Lyla and Nixie follow Zac to school, but the school principal confronts them and takes Sirena's Moon Ring.

When a waitress spills a drink on Lyla, she rushes to the cool room -- just before transforming into a mermaid!

Rain keeps the mermaids indoors and unable to look for Zac. Lyla and Sirena try to use the Moon Ring to stop the rain, but they create a blizzard.

Joe has a new boat and takes it out for a spin. His fish finder locates a dolphin, but it's not like any dolphin he's seen before.

Zac's struggle with his merman secret intensifies when his girlfriend, Evie, throws him a pool party.

It's a full moon, and the mermaids think that if they keep Zac out of the moonlight, he'll lose his powers and return to his land-dwelling self.

While listening to Sirena sing, Lyla has an idea: If Sirena sings the "Enchantment Song" to Zac, he'll fall under her spell.

Against Nixie and Sirena's advice, Lyla helps Zac get to the Moon Pool. But when the entrance suddenly closes, they're trapped inside.
