The Merman Code is the 17th episode of season 2 of Mako: Island of Secrets.


When Erik dives down and touches one of the rock outcrops on Mako reef, he's transported into a sphere of endless water with no way out.


Ondina and Erik are spending increasingly more time together causing Mimmi to feel neglected. Meanwhile, Cam studies a photo of the stone pedestal from the merman chamber and discovers that the stone carving matches a satellite photo of Mako Island. He also suspects that the symbols on the carving correspond to the outcrops on the reef surrounding the island. He shares his thoughts with Erik and the two decide to investigate the outcrops on the reef. The two find a symbol of a trident on the outcrop but when Erik touches it, he is teleported into a realm of endless water with no way out. Cam rushes back to land and asks Zac and the three mermaids for their help to rescue Erik. While out on the island, Ondina and Mimmi get into a heated argument about their different opinions of Erik causing a rift between them. The group soon realize that they must risk activating the chamber to rescue Erik. Mimmi is able to figure out the order of the pedestal's code and Erik is set free when Zac activates the chamber. Afterwards, Ondina and Mimmi reconcile with Ondina promising never to let Erik come between their friendship.



  • It is revealed Zac is the only one that can activate the Merman Chamber.
