A lot or a little?

The parents' guide to what's in this TV show.

Educational Value

Much of the series is set underwater, and one character has an interest in marine biology, so viewers learn some things about the species indigenous to the Australian coast. 

Positive Messages

This story of friendship and adventure has good messages about self-image and self-esteem, as well as embracing change and learning new things. There's some bullying in play, from characters both on land and underwater, but the girls always stand up for themselves and for others who are picked on. The girls are forced to keep their secret from family and friends, but it's for good reason. 

Positive Role Models & Representations

Rikki, Cleo, and Emma are good friends whose bond is even stronger now that they share such a big secret. They support and encourage each other, and they always stand up for those who need a friend. 

Violence & Scariness

Some bumps and tense moments when the girls encounter bullies, both on land and underwater.

Sexy Stuff

The show is inspired by a live-action series called H2O: Just Add Water.

Drinking, Drugs & Smoking

What parents need to know

Parents need to know that H2O: Mermaid Adventures is an animated series based on the popular Aussie show H2O: Just Add Water. This story parallels the original -- three friends are magically transformed into mermaids on a trip to a mysterious island -- and its strong themes of friendship, self-confidence, and self-image are evident here as well. Because the girls can talk to the ocean creatures they encounter, there are some opportunities to learn about some of the species that inhabit the Australian coastal waters. Expect some tense moments that show bullying or characters in peril (a turtle caught in a fishing net, for instance), but the endings are always happy.

Oversexualized mermaids

I just can't get over the weird mermaid bras they have. It feels way to oversexualized and not appropriate for my 5 year old. The writing is also atrocious... Continue reading

Over-sexualised, bullying and talking fish

Talking fish and magical mermaids saving the day - great for 5 year olds.
Very bitchy characters. Very small clothes. Great for ... nobody.

What's the story?

H2O: MERMAID ADVENTURES is the story of three friends united by a magical secret. An overnight trip to Mako Island changes the lives of Cleo, Rikki, and Emma when a mystical force transforms them into mermaids and gives them powers to manipulate water. Even better, they discover they can communicate with other ocean creatures and soon make all sorts of new underwater friends. But keeping their secret won't be easy, so they lean on their friend Louis to help guard their magical identities.  

Is it any good?

This engaging animated series has strong examples of friendship and self-esteem that will resonate with young audience members. What Rikki, Cleo, and Emma initially see as an inconvenience quickly becomes an exciting new adventure for them, and they embrace all that their new identities enable them to do. Rather than focusing on what the change has cost them (most obviously the ability to touch water without transforming, which has its complications), they embrace how it's altered their life in positive ways, giving them new friends and new opportunities.

Much of H2O: Mermaid Adventures' plot parallels what was established in the live-action series on which it's based, but there are a few notable changes that will further delight kids. The fact that the girls can talk to the sea creatures they meet opens up a whole new pool of characters to enjoy, from Zita the curious eel to Sue the mystical manta ray. As Rikki, Cleo, and Emma balance their lives under the sea and onshore, they're challenged in new ways as individuals and as a team.
