50 free Mako Mermaids trivia questions with answers — trivia quiz, new questions added Oct 2026.
Mako Mermaids ran for three series and 68 episodes, and its premise is a neat reversal of the usual mermaid story: here it is a teenage boy, Zac, who falls into a magic pool and grows a tail, and the mermaids who must leave the water to deal with the consequences. The result is part teen drama, part fantasy adventure, with full moons, ancient weapons and a pod that does not forgive easily. This quiz covers the whole run. Expect questions on how Zac gains his powers and what he does with them, on Lyla, Sirena and their friends learning to live on land, on Rita's double life, the trident and the merman chamber, Evie's time with a tail, and the arrival of Ondina, Mimmi and Weilan. There are also questions on the cast, the people who made the show and where it was filmed. It is pitched at fans who have watched the series through at least once. The opening questions are the ones most viewers will get; later ones reward anyone who remembers a single episode in detail. Every answer comes with a short explanation, so you can settle arguments as you go.
