Average "H2O: Just Add Water" Season 1 Quiz | 10 Questions | For Children

Answer: Rikki

Rikki had never met Cleo or Emma. Their friendship and trust in one another began after Rikki had stolen Zane's boat after he had tricked Cleo onto it. As she could not swim, he pushed the boat out onto the water and she got trapped. Rikki then ran up, jumped on and was able to restart Zane's boat. Rikki soaked Zane when they sped off onto the water before meeting Emma, who Cleo asked, "Do you want a ride?". Emma then said, "Are you licensed?" which was followed by Rikki answering, "Are you my mother?".

Answer: Mako Island

Mako is the uninhabited island located 50 kilometres from the Gold Coast. After becoming trapped on the island, the girls find themselves in a cave where the only way out is to swim through an underwater tunnel. Just before they did, the moon passed over the volcano on the island, and the water began to bubble like a jacuzzi.

At first they thought it was spooky, but they were able to swim out from the underwater tunnel and were rescued by the water police. The next day, they found out after they come into contact with water, they turn into mermaids after 10 seconds and they also learned that they each have powers.

Answer: Lewis

After being thrown into the pool during a party, Cleo turned into a mermaid in front of Lewis. He helped her out of the pool and Rikki helped to dry her off using her powers and they fled the scene before anyone saw them.

Answer: They experience random mental states

On each night of the full moon, the three girls try their best to defend themselves from making eye contact with the moon or its reflection. This has failed in several episodes; it has seen them changing into people who they are not when they are in a normal human state during the day.

For example, Emma turns into a party crasher, recklesss, when in reality she is a very careful and organized person.

Answer: Miriam Kent

Towards the end of Season 1, Dr Denman and Harrison found out that the girls were mermaids after spotting their faces in an underwater camera whilst they were swimming to Mako Island. Shortly after the girls are captured at the Moon Pool by Denman and Harrison, Zane wanders in and discovers the mermaids he was hunting for were Emma, Cleo and his then-girlfriend Rikki.

In all of the first season, Lewis, Ms Chatham, Dr Denman, Zane and his father Harrison were the only people to find out the girls' secret. Miriam never uncovered their secret or even suspected the girls were in any way out of the ordinary.

Answer: Three girls who became mermaids 50 years ago

The first locket was found by Emma at the Moon Pool and was later given to Cleo for safe keeping, followed by one being sold in a pawn shop and the other on Ms Chatham's person. Ms Chatham and her two friends Julia and Gracie became mermaids almost 50 years before Cleo, Rikke and Emma.

The girls were just as close and had just as many secrets. The lockets became a symbol of their secret and their eternal friendship. Cleo was gifted with Gracie's locket, Rikki was gifted with Julia's and Ms Chatham passed on her locket to Emma, relieved that all three lockets were back together again after being apart for so many years.

Answer: Elliot Gilbert

After reading Cleo's diary containing all of Cleo's personal thoughts and secrets, Kim became convinced that Cleo and her friends were mermaids and all had magical powers. This was furthered by catching a small glimpse of Cleo's tail in the bathroom. Elliot latter became convinced when Emma accidentally manipulated the shower to hailstones while Elliot was in there.

They also believed Miriam was a mermaid and after Cleo and the girls discovered Kim was suspicious, they set up Angela to throw Kim and Elliot off track.

This worked, as Cleo was later able to convince Kim that the tail she saw was a costume and the diary was for a school project on fairy tales, which Kim then believed to be the truth as she realised Cleo couldn't swim! Or so she thought.

Answer: Singing Voice

Cleo originated with a terrible singing voice, but after accidentally catching a glimpse of the full moon's reflection, her voice changed into that of a singing mermaid, even temporarily taking away her tail as her hands were wet and her tail never appeared.

Her voice attracted the attention of the likes of Lewis, Zane, Byron and many more of the teenage boys on the Gold Coast, eager to hear Cleo's voice. This was shortlived as her voice changed back to being terrible at singing once the sun was up and the moon was gone.

Answer: The Lorelei

The name Loreli was chosen by Ms Chatham and her husband when the boat was built because it represents secrets of the sea - reference to her secret life as a mermaid when she was Cleo's age. Ms Chatham lived on this house boat for many years so she could always be on the sea and close to her memories as a mermaid 50 years before.

This boat contained many of her prized possessions, including pictures of herself with Gracie and Julia as mermaids which were almost exposed when her boat was shipwrecked accidentally after Zane gave chase to her boat after she scratched the side of his Jet Ski on her way out of the harbour (which has happened on more than one occasion, according to Zane).

Answer: The girls' tails and powers were withdrawn for 12 hours

Ms Chatham informed the girls that now that Dr Denman and her crew were aware of their extraordinary powers, they were forced to take action so that Dr Denman would leave the girls alone and not expose their secret. However, what Ms Chatham failed to tell them was that the eclipse would only draw their powers away for half a day.

This was because, as Ms Chatham later told Lewis, if the girls believed their powers were gone forever, so would Dr Denman.
