An animated reboot of the live-action H2O: Just Add Water, three teenage girls are turned into super-powered were-mermaids (the touch of water forces the transformation) after they are trapped in a magical cave during a full moon. With the help of a hermit crab and a human nerd, they struggle to keep their new lives secret while helping out the nearby sealife.

While his peers have all turned white, Katak is still small and grey. To prove that he has grown up and to grant the last wish of his adored grandma, Katak departs on a perilous journey to the Great North.
