Go To

H2O: Mermaid Adventures is an Animated Adaptation of H2O: Just Add Water made for Netflix.

H2O: Mermaid Adventures provides examples of:

  • Adaptation Dye-Job: Rikki has been made a red-head, fixing the problem of two blondes and a brunette the original series had.
  • Adult Fear: "Three Days Underwater" features Mr. Chadwick fearing that Rikki has run away after the former has forgotten the birthday of the latter's late mother and that he might ultimately never see his daughter again.
  • Animesque: The show's art style. It basically looks like an anime cartoon but in the modern flash style.
  • Ascended Extra: A minor example. Byron and Miriam do not undergo Chuck Cunningham Syndrome and are thus present the whole series.
  • Bermuda Triangle: A local equivalent appears in the episode "Dolphin City Triangle."
  • Because Destiny Says So: Sue the Manta Ray tells the girls to not to question why they are mermaids as it is the will of the universe.

  • Bloodless Carnage: A minor aversion in "Jaws-ache" where Berk's broken tooth is removed and some blood is shown in the water. A less minor one appears in "A Strange Phenomenon" where Cleo has a rather large cut on her hand and blood is clearly visible.
  • Canon Foreigner: The sea life, Mr. Lambert and many others.
  • Cassandra Truth: In "Reported Missing", Kim discovers that Cleo, Rikki and Emma are mermaids via reading Cleo's diary. When she tells her parents, they don't believe her. When Kim tells Emma's brother Elliot he doesn't believe her either but she talks him into proving it with her.
  • The Cavalry: The sea life serves this purpose during the climax of "The White Mermaid."
  • Color-Coded for Your Convenience: The girls all have a different coloured tail as mermaids: purple for Cleo, red for Rikki and orange for Emma.

  • Comic-Book Fantasy Casting: Lewis resembles Michael Jones of Rooster Teeth's Achievement Hunter.
  • Continuity Nod: "The Creature from the Bay" features Danny the Octopus claiming that he is a star again upon seeing underwater photographers to which he is told that no one is interested in a has-been octopus, all referencing the episode "Dolphin City Mascot."
  • Crying Wolf: As a result of too many pranks, Teddy the sea turtle is not believed when he tells the other sea creatures and the mermaids about an undersea volcano that is going to erupt soon in "Imminent Danger", at least until the mermaids actually do look at it.
  • Damsel in Distress:
    • Rikki gets trapped in a net in the episode "Caught in a Net" when explaining to Teddy the sea turtle why he should trust the humans from the oceanic centre.
    • Cleo gets captured by treasure hunters looking for the sunken ship the White Mermaid. First chance she gets she throws herself into the sea.
  • Department of Redundancy Department: In "Valentine's Day", Lewis refers to the girls as "spies, backstabbers, traitors" when he finds they've been following him and Abby around. "Backstabber" and "traitor" are synonyms.
  • Dumb Muscle: Burk the hammerhead of the Vandals isn't quite the brightest pearl in the sea.
  • Fall Guy: Or "Fall Girl" in this case. Miriam turns Rikki into one in "Underwater Takeover" by stealing her phone and using it to call the fire department that there was a fire at their school, which there wasn't. Miriam then plants the phone back in Rikki's bag, post-fire department's arrival, and when the call is traced back to her the belief is she is the one that called the false alarm. Miriam's reason? There was a test that would cause her to miss a big sale.
  • Fangirl: Rikki shows some minor cases of being one in "Poseidon's Daughter" when she says she'd jump into an actor's car.
  • Fanservice: A show set in (presumably) Australia with the three leads being attractive teenaged girls and there are many scenes set at the beach. Girls in swimsuits is common in this show. Cleo wears a one piece, a bikini on one occasion, and Rikki and Emma both wear bikinis.
  • Fiery Red Head: Rikki. And she has the power to boil water too.
  • Gold Digger: Not really but Rikki fears her future stepmother is one in "The Lost Ring."
  • Goldfish Poop Gang: The Vandals are as incompetent as they get when you think an eel, an octopus and a hammerhead shark would be quite formidable.
  • Gossip Evolution: "It's in the Bag" features Rikki saving Ziggy the Clown Fish after a shell fell onto him. He goes on to tell the other sea life how he was afraid it had been a shark or an octopus and sure enough later tellings of the story have it be either of those two and the final being both.
  • Grumpy Old Man: Well, the words used by Carlotta the jellyfish were "cranky old crab" to describe Bernie the hermit crab in "Handle with Care" but he neither likes Carlotta singing outside his cave nor Teddy the sea turtle and his clown fish friends playing outside it.
  • Hair Color Dissonance: Cleo's hair is purple but referred to as brunette or black depending on the person, possibly meaning it is intended to be a very dark brown.
  • Hidden Depths:
    • In "The Mysterious Seaweed" a picture of Boris Karloff as Frankenstein's Monster can be seen in Zane's locker. Apparently he is a fan of classic horror films.
    • In "The Lost Ring" Rikki shows interest in a comic book implying she might have an interest in such things.
  • Hong Kong Dub: With the animation having been done in Germany, with the lip-sync meant for German, this is the end result.
  • Most Annoying Sound: In-Universe example. In "Bad Waves", Rikki finds Lewis' attempts at trying to figure out what the mysterious sound the girls heard to be worst than the sound they actually heard.
  • Naked People Are Funny: Or rather crabs. When the toy car that is Bernie's shell gets stolen by an octopus, Teddy gets a good laugh upon seeing him.
  • Oh, Crap!: Emma has a moment in "Trapped" when her brother Elliott has stolen her phone, which has personal things on it. It gets worse when Elliott shows the phone to Zane who finds a particular video on it that he makes viral and Emma the laughingstock of their school.
  • Oh My Gods!: Bernie exclaims "in the name of Poseidon" in "Handle with Care" when he gets aggravated by Carlotta's singing, and later when he's trying to get the Vandals out of his cave.
  • Orichalcum: the magic crystals in "Dolphin City Triangle".
  • Our Mermaids Are Different: It uses the Splash method.
  • Power Makes Your Hair Grow: The girls’ hair becomes several inches longer when in mermaid form.
  • Seashell Bra: Rikki has one as a mermaid in contrast to Emma and Cleo who have, stars and coral respectively, and even more in contrast to the usual seashell bra in animation where it is literally just two shells placed on her breasts with no strap or anything.
  • Setting Update: The show is set in the 2010's and while it might still be set in Australia, it is possible it was set somewhere in the America's due to the mentioning of an Aztec treasure being nearby or something along those lines.
  • Shout-Out: In "Dolphin City Mascot" Abby says that Danny will be more famous than Lady Gaga in regards to Danny's predictions of sporting events.
  • Sticky Fingers: Two examples both involving octopi.
    • A literal example due to Danny being an octopus as Cleo finds out when rescuing him from the oceanic centre in "Dolphin City Mascot."
    • A straight example involving a different octopus that has stolen many an object out of boredom in "The Lost Ring."
  • Stock Ness Monster: "The Creature in the Bay" features Rikki being mistaken for one when her tail is spotted splashing at the surface by Emma's brother Elliot and the Loch Ness Monster is mentioned in the episode as well.
  • Talk Like a Pirate: Apparently pirate captain Edward the Cruel spoke like this as indicated in "The Return of the White Mermaid" when the Stone Circle swaps his soul with archaeologist Stanley Finch's.
  • Tentacle Rope:
    • Happens to Cleo and Emma in due part to a bored octopus in "The Lost Ring."
    • Danny does actually employ his tentacles in such a fashion against Cleo in "Underwater Takeover."
  • The Prankster: Teddy the Sea Turtle becomes one out of boredom in "Robot Duel." He is at it again in "Imminent Danger" until it results in Crying Wolf for him.
  • Those Two Bad Guys: Three technically but the Vandals fit the bill in name only as they are otherwise quite incompetent.
  • Tomboy with a Girly Streak: A minor example but Rikki is shown admiring a pearl necklace in "Kidnapped!"
  • Total Eclipse of the Plot: While the eclipse does not occur the whole way through of "Imminent Danger", Cleo glimpsing a lunar eclipse is what causes her to lose her powers for the episode.
  • Use Your Head: Berk actually uses his head to break some underwater crystals in "Dolphin City Triangle." In the later episode "Imminent Danger" he uses his head to drive nails into a sunken ship that will be used for shelter in the event of a possible tidal wave.
  • What the Hell, Hero?: Rikki and Emma give Cleo a brief one in "Valentine's Day" when she actually uses her powers to splash Abby, who is on a gondola ride with Lewis, on a clear day risking her finding out about them being mermaids.
  • You Gotta Have Blue Hair:
    • Cleo has purple hair.
    • Miriam has dull pink hair.
  • You Watch Too Much X: Mr. Sertori's reaction to Kim telling him and Mrs. Sertori that Cleo is a mermaid.
