My 9 year-old daughter loves this show and has been trying to watch it on Foxtel but as usual they have been airing the episodes out of order. My 7 year-old isn't quite so interested. The story is based on the three main mermaid characters trying to come to terms with the fact that they turn into mermaids at inconvenient times. This creates some awkward moments such as getting in trouble with your parents for not washing up. They also have magical powers. There is a boy who is friends with the mermaids and is trying to help them learn about their powers and how to control them. There is a bit of pre-teen type romance in it but nothing that I have a problem with for young girls - I'm not even sure I have seen any characters kiss.
