Funny / Mako Mermaids: An H₂O Adventure

• The girls' over-the-top reaction to seeing a cat, which they regard as a frightening monster, is hilarious.
  • When it's Mimmi and Ondina's turn, they run into each other while screaming in terror. Contrast Sirena, who picks Poseidon up and coos over him.
• The girls' attempts at walking for the first time are terrific.
  Nixie: We are about to enter a world of chaos and danger. Follow my lead. (takes one step and falls flat on her face)
  Lyla: So the plan will be to hope the boy trips over us?
• Cam tells Nixie, "If you wanna friend me, hit me up." She's confused, but obliges by striking him in the shoulder.
• Nixie's a borderline Comedic Sociopath as she zeroes in on the idea of Sirena making bracelets for money — which she would share — and negotiates a deal with Evie to sell them in the cafe without, you know, consulting Sirena or considering that it's a lot of work. Sirena protests that it will take ages just to gather the materials, and Nixie just blithely says, "Sorry. Better get started, then."
  Sirena: I haven't even eaten.
  Nixie: [to Carly] Yeah, she'll have hers to go.
• "So what do we know about moon pool water? And if anyone says it's water from the moon pool, I'm going to be annoyed."
• The girls accidentally turn Poseidon (Rita's cat) into a clone of Evie. To say hilarious misunderstandings ensue would be an understatement, helped along by Poseidon's airy and superior tone of voice.
• After Ondina accidentally turns Erik into a cat:
  Zac: Promise you'll never turn me into a cat.
  Evie: Of course not. [Beat] I prefer dogs.
• Sirena's first encounter with a telephone is quite a scene. As she and Lyla are sick at the time, they at first think their ears are ringing. Sirena sees one button (the speakerphone button) flashing on the phone and presses it, and David starts speaking.
  Sirena: Wow, you sound just like a real boy!
  David: That... would be because I am a real boy.
  Sirena: Really? {examines phone} You don't look like one.
  David: Gee, thanks. Wait, you sound familiar. Do I know you?
  Sirena: I'm pretty sure we've never spoken before.
  David: Yes, we have! You're Sirena, right?
  Sirena: How did you know?!
  David: It's David, over at the Ocean Café!
  Sirena: David? {tries to pry the phone from the wall, as though looking for David behind it} How did you get in there?!
  David: ...Through the front door like always?
• Evie rants about how she can't take a shower thanks to her new mermaid powers, then asks Zac how he bathes. He awkwardly points out the ocean.
  Evie: ...Ew.
• Erik asks how he was supposed to drop the bombshell that he's a merman.
  Erik: Hey everyone, I'm Erik, from an ancient line of mermen. Who's up for a frozen yogurt?
• Sirena tries getting Moonstruck!Evie to come back to her senses. It seems to work for a second... then Evie belches loudly in Sirena's face.
  • Moonstruck!Evie later compliments Sirena's hair, especially how it moves underwater. Carly tries drawing attention to her own hair, to which Evie stares at her judgmentally, and recommends using a seaweed conditioner. Carly looks so bewildered, especially when Sirena nods in agreement.
