The H2O Just Add Water girls Cleo, Emma, Rikki and Bella have lost their mermaid powers, so they need to find out why and get them back before going off to college. They are staying with Mrs Chatham for the summer, so she can help them figure things out before its too late!! But too late for what??!!! What could be happening in Mako Island??!!! #h2o #justaddwater #h2ojustaddwater #h2ojustaddwatermermaids #h2ojustaddwatergirls #mermaids #makoisland #makomermaids
