The Australian television series H20: Just Add Water debuted in July 2006. The show will appeal to children and young adults as it tells the story of three best friends who become mermaids after becoming stranded on Mako Island. The girls jump into a magical pool, which is underneath a dormant volcano. When the full moon drifts over the pool, the girls become the magical creatures. After their rescue, the girls are unaware of the change until they come into contact with water. Once water touches them, they quickly turn into mermaids. The three friends are Emma, Rikki and Cleo. The girls are 16 years old and live in Australia.

The girls soon discover that they have new water related powers along with their fins. Rikki can manipulate the heat within water. For example, she can make it warm up or even boil. Later, during the series, she gains power over fire and lightning. Emma has the power to freeze water, and her abilities develop into control over snow, clouds and ice. Cleo
