Dangerous Waters is the ninth episode in Season 1 of H2O: Just Add Water.


Rikki uses her abilities as a mermaid to earn some quick cash but when she accidentally becomes involved in a fish smuggling operation she sets out to get her revenge.


One of Cleo's pet fish has died. Rikki, in the attempt to make up for her brusqueness, tries to find her a replacement fish. She uses her mermaid powers by diving where no fish collector can dive and picking out a fish that strongly resembles Cleo's lost one. She meets Barry Rollins who offers her to pay her well if she sells him fish like the one she was bringing to Cleo. Rikki agrees, believing that the man is what he says he is (a marine park breeder of rare fish), but when she learns the man who hired her is lying and actually is selling the fish illegally to earn large profits, she takes it upon herself to get revenge and deliver him to the authorities. Rikki uses her powers to attack the man, Cleo and Emma eventually tell her that she has done enough.


  • This is the first time Rikki used her powers openly on a normal human.
  • Cleo has a fish called Hotstuff, named in honor of Rikki who got it for her.
  • This episode marks the first time the mermaids use their powers to fight evil.

Kim: Mom told me that she's about to start making dinner. She wants to know if any of you guys want to stay?
Lewis: Sure.
Rikki: I'm starved.
Cleo: What are we having?
Kim: Fish!
Lewis: Oh no!
Laugh and groan

Rikki: Cleo, look, I'm sorry. I didn't know about the salt-water thing. I should have, but I didn't. What can I say?
Cleo: That's okay. I know you're not good with the whole empathy thing.
Rikki: Yeah, well, it's... you think?
Cleo: Oh yeah.
