Hey, I was hoping I'd see you today.
Me too.
I was thinking we could spend the day together.
What?
There's nothing I'd rather do, but I can't.
I've got a physics exam. It's really important.
Carly and I were just about to leave.
Okay.
- Soon as I'm done, all yours. - It's a date.
- Hey, David, you have to see this clip. - Carly, we have to go.
But it's about your favorite subject, mermaids.
Really? - Some guy in a kayak got it on video.
A mermaid, as if.
It's not that ridiculous.
I'm sure it's a hoax.
Of course it's a hoax, but I have to hand it to this guy.
It looks pretty real. Check it out.
Exams, remember?
You two better get going.
Fine.
I'll see you later.
If we're lucky, we'll make it home tomorrow.
It sure has been a great trip.
Hey, can you hear that?
It's so beautiful.
Hey, are you getting this?
No way, you're...
You're a mermaid.
There's not much seaweed around at the moment.
The dugongs must've hogged it all.
We hardly got any.
Still, I think we deserve a reward.
You're right. We shouldn't work on an empty stomach.
Where were you?
You were supposed to help us gather seaweed for making ice cream, remember?
Ice cream?
Yes, your favorite.
- David had to leave. - Oh, you mean the exam.
Zac had to go to that, too.
It must be so weird sitting in a building to do an exam.
I know. How do they stand it?
- Mermaid exams are much more fun.
Remember when we sat our test for navigating ocean currents,
and that cranky old sea turtle tried to take a bite of your tail?
Yeah, that was hilarious, minus the snappy turtle part.
Those were the days.
Well, I guess we'd better go and collect more seaweed.
Are you coming?
You know the deal.
No phones, no talking,
no eating and no cheating.
No distracting other students,
and if you finish early, you may leave quietly.
Good luck.
Turn your papers over.
Your time starts now.
Go away.
Does anyone know that girl?
What's going on, Sirena?
You know you shouldn't be here.
Hi, David.
Sirena, what were you doing? That exam was really important.
I brought you lunch.
I thought we could have a picnic on the beach.
It's lovely of you to think of me, but you have to go.
I'll see you after school, all right?
Once I'm done, I'm all yours. We can do whatever you want.
- Promise? - I promise.
Sirena?
- What are you doing here? - I brought lunch.
Nice of Sirena to join us.
It's not like her to let us do all the work.
Did she seem a little odd to you earlier?
No more than usual.
Hey, we were just talking about you.
Are you two gonna be here long?
Well, this is our home, so, yeah.
Let's get started on the ice cream.
That old, tough seaweed won't make good ice cream.
It's far too bitter.
What you need is young, fresh seaweed.
We looked everywhere and we couldn't find any.
I know where there's a good crop growing.
Out past the far eastern edge of the reef.
That's a long way.
Well, you could make the ice cream with what you already got...
it just won't taste very good.
I guess we do want the best seaweed available.
Will you at least come and help us?
I'll meet you out there.
I just have something I need to do first.
Okay, but don't be long.
There you are.
Now we can be together.
- Have you done something with your hair? - You like it?
It's lovely.
- Are you ready? - For what?
Hey, David!
I've got a delivery ready, if you're not too busy.
Oh, right.
You promised we could be together.
I know, and I'm sorry, but I really have to do this.
Sirena!
What are you doing?
Sirena!
David is mine!
Sirena, wait!
Did you see that?
It's like my boat's possessed.
It's the currents here, they're weird.
You can say that again.
What was Sirena thinking? This seaweed is ancient.
We swam for miles, and she didn't even turn up to help.
Sirena?
Why does she keep disappearing on us?
I think we should find her.
"David is mine"? What does that even mean?
She was in another world. Like, she couldn't even hear me.
Hmm.
Well, the next full moon is a while away.
Why would she be like that?
Have you seen Sirena?
She just took off.
- Is something up with her? - Why?
She used her powers in the open.
And she's obsessed with David.
So what's new?
Hey, you guys have to see this.
We're kind of in the middle of something.
Someone's filmed a real live mermaid.
I'm sure it's a hoax, but they've done a great job.
It really looks authentic.
Oh, that's weird.
The clip's been taken down.
Not to worry.
Like you said, it's just a hoax.
Oh, wait! I saved it on my phone.
If we're lucky, we'll make it home tomorrow.
It sure has been a great trip.
No! Turn it off.
What are you doing?
Those videos just feed people's fears and cause nightmares.
I think we're mature enough to handle it.
- Ow! Hot! - Ah!
I heard about this model. It always overheats.
I'll get it fixed.
Let me see it.
Does anybody have those little ear thingies?
Hey, can you hear that?
It's so beautiful.
Hey, are you getting this?
Well?
It's a northern mermaid siren song.
They've been banned in our pod for over 200 years.
- Why? - They were used to lure sailors
into the water and make them forget.
So, Sirena must have seen the video and been enchanted.
But why would Sirena be enchanted and not Carly?
The song is only effective on men,
and only when they hear it sung by a real mermaid.
Then why would Sirena get enchanted?
Northern mermaids are immune to the song
so I'm guessing it's because she's a southern mermaid.
So if Sirena sings the song to David?
He'll forget who he is, his life, everything.
He'll only want to be with her. Nothing else will matter.
That's right.
David and I will be very happy.
Sirena, let's sit down and talk this through.
There's nothing to talk about!
All that's left is to sing David to me.
Please don't interfere.
Okay, Sirena, enough with the creepy siren stuff.
The moon pool is ours.
Stay away!
We've gotta stop David from hearing that song.
He'll be at the café.
It was bizarre.
The boat was totally out of my control. It must need a tune-up.
Either that or an exorcism.
I think that's it.
Yeah, yeah, I'll lock up.
- Have a good night. - You too.
Sirena.
David?
Maybe he isn't here.
He would never leave the café unlocked.
His boat's gone. - She's taken him!
- Where? The moon pool.
Let's go. - No!
I'm the only one who's immune to the enchantment.
You're not doing this on your own.
You're not immune either.
So I won't listen.
I'll sing right over the top of her, drown out the noise.
Ondina, that's brilliant!
- It is? - Yeah.
Do you like your new home?
Yes.
You're a mermaid.
- Do you mind? - No.
I love mermaids.
We're gonna be so happy here.
Go away. He's mine!
You are under the spell of the mermaid song.
Fight it!
I told you not to interfere.
Sirena, listen.
Cover your ears!
Where am I? What's going on?
Ondina, it worked.
Ondina!
What?
Oh, right.
Sea slime, soundproof.
Are you okay?
I think so.
What happened?
Have you come to take me away, too?
In your dreams, sailor.
What?
I'm so sorry about yesterday.
I know I nearly ruined your exam.
You brought me lunch. It shows you care.
Hey, David, you feeling okay?
You heard?
I woke up in my tinny in the middle of the ocean.
I don't know how I got there.
- Exam stress. - Yeah, I get that, too.
I passed!
Oh, you go, girl.
So did you.
And me.
I don't wanna know.
You're right to be worried.
No one else got a mark like that.
Oh, no.
You topped the class.
- Seriously? - See for yourself.
- Yes!
I got your phone fixed.
- No more overheating. - Thanks.
But the video clip you were trying to play got deleted. Sorry.
No big deal.
I found it again online.
No!
