i'm still open for suggestions for crossovers.

-h2o-

It's karaoke in the juice net café, so everybody is there. Rikki goes over to Wilfred to enter Cleo. Back at their table, Lewis is outing his disgust for karaoke.

"I hate karaoke. It's just a bunch of wannabe's searching for their fifteen minutes of fame. I think it's quite deluded."

"And our next contestant is Cleo Sertori."

Lewis quickly looks at his girlfriend.

"Except for you Cleo, cause you will be really, really good."

"I didn't put my name down."

Rikki pulls her off her chair.

"I did. C'mon I know you want to."

"I can't."

"Yes you can, go on. Make us proud."

Cleo steps on the stage, while Emma and Rikki are waiting for her to start.

"You're going to regret this."

"She'll be fine."

"You haven't heard her sing."

Cleo starts to sing and indeed it sounds awful. It is even that bad that Wilfred takes the microphone down. "Put it together for Cleo." She sits herself back down, red of shame. Lewis goes towards her.

"I thought you were okay Cleo."

-h2o-

Cleo goes back to the marine park. She is feeding the dolphins when suddenly the old lady warns her.

"Beware."

"Beware of what?"

"What do you think?"

"I don't know. You're the one telling me to beware."

"Haven't you learnt anything yet? What's today?"

"Umm, Wednesday."

"It's the full moon."

"Yep, we remembered it, we're getting ready. But is it going to be as bad as last time? Are weird things going to happen to Emma again? Or Rikki? Or me even? I hate that."

"Forewarned is forearmed. But only sometimes, remember don't touch water when the moon is full."

Cleo's phone goes off. "Mom… milk, sure." She puts her phone down and notices that the old lady is once again gone. "I wish she stopped doing that."

-h2o-

Cleo comes home after work. She goes over to the fridge to put the milk in it when Kim stops her.

"I wouldn't do that if I were you."

"Why not?"

"Alright, whatever suits you."

Cleo opens the fridge, but immediately wished she had listened to Kim because she gets an electric shock.

"Told you."

"Aww, what was that?"

"Dad says that there is something wrong with the fridge. So we should stay out of it."

"Thanks for warning me."

"I did warn you."

"No, you said that…"

But before a real fight could start off, the doorbell rings.

-h2o-

Cleo opens the door and finds Rikki and Emma outside.

"Hey guys, come in. Everything is been set up, heaps to drink and pizza is been ordered."

"Cool, what movies did you get?"

"I thought you were getting the movies."

While Rikki shakes her head, the door opens again and Lewis comes in.

"Evening ladies. Now I wasn't sure what films you like, so I thought I play it safe and I got a chick flick. But I did get two horror movies."

"Lewis, what are you doing here?"

"What?"

"What are you doing here?"

"Duh. I'm here to help. Remember I'm the only one who want be affected by the full moon. So if any one falls asleep, I'll be right beside you."

In the meanwhile Cleo's father came in and heard the last of Lewis.

"Will you now?"

"Hello, Mr. Sertori."

"I got my eye on you."

"Dad."

Cleo's mom gets to her husband. "Don." And pulls him away. And for the first time, Kim is there to save the moment.

"Don't worry Lewis, you can sit with me."

-h2o-

Later that night, the girls, Lewis, Cleo's dad and, unknowingly for everyone, Kim are watching the horror movie. The movie has got to the highlight.

"Don't open the door, don't open the…"

"Argh."

Kim comes behind the couch.

"She opened the door."

Don notices Kim and gets up.

"Kim. You shouldn't be watching this. This is for adults."

"I'm an adult."

"And it's past your bedtime too. You brought the movie Lewis, it's your fault, you should be supervising."

Don gets Kim to her room.

"Your dad hates me."

"My dad hates all guys Lewis, don't flatter yourself."

Suddenly an electric monster rises in the TV and it falls out.

"Great, no TV anymore."

"Hey, what time does the moon rise?"

"About two minutes. Ago."

-h2o-

While Lewis closes all the curtains, the girls hide under the blanket. When Lewis turns back around, he sees Cleo looking into her glass, where the moon is reflected in. But when she reaches with her arm, Lewis stops her.

"Cleo are you alright?"

"I'm fine, why?"

"You just had quite a close call."

"Really? This is really scary, isn't it? I have to go to the bathroom."

"Someone should go with you."

"Oh yeah, my dad would really love that and besides I'll be fine."

-h2o-

Cleo gets to the bathroom. She stands before the mirror but the leaking off the tap makes her look down. In the water, she sees the reflection of the full moon. She can't help herself and touches the water.

-h2o-

Rikki gets up.

"Alright I'm getting thirsty, anyone else interested?"

"Sure, why not?"

Rikki heads over to the fridge, she touches the handle, but immediately pulls back.

"Aww."

"What is it?"

"Probably nothing, just a little shock."

She tries to open it again, and this time she succeeds. But the same electric monster from the TV comes out of the fridge and lifts her up. He drops her and returns to his fridge.

"Alright, now everybody did see that right?"

"Yeah."

"Are you okay?"

"I'm fine thanks."

"Probably because of your higher mermaid resistance. What was that?"

"Guess."

"Great, so we don't even get a break on a full moon?"

"Where is Cleo, she is already gone a long time?"

She suddenly comes in and starts singing beautifully.

"What happened?"

"She can sing."

Rikki and Emma sit down. Cleo's parents and sister get down the stairs.

"Something is not right."

"Look wet hands, but no tail."

Emma taps Rikki on the shoulder and points to Lewis, who's sitting open-mouthed.

"Wow, she is amazing."

"This isn't Cleo. It's got to be the full moon."

Suddenly there's a knock on the door and Cleo's mum opens it. It's Byron.

"Who's that singing, she is incredible. Cleo."

"She must have had singing lessons, I guess."

"It really worked."

She stops singing.

"How did I do?"

"You were good."

"I can sing. I can really sing. I mean, it sounded good to me, but sometimes it's hard to tell."

Emma and Rikki get up.

"Cleo, we need to talk."

-h2o-

They guide her to the kitchen.

"Cleo listen, you touched water and the full moon is doing something to you."

"I can sing."

"Cleo wake up. You're a bad singer."

"You're just jealous, but that's okay I still like you. You're my friends. And if you want you can pick out my next song."

"Let's get Lewis."

-h2o-

Cleo's mum is cleaning up the popcorn.

"No one in our family has ever been a singer."

"Well I sing now and then." She and Kim look at Don. "Yeah, okay, point taken."

The girls get up the stairs.

"Lewis, we need you right now."

"Cool, Cleo is so cool. I'm so there."

Byron also makes a movement to go upstairs.

"Hey I want to see Cleo too."

Cleo's dad gets out of his couch.

"Wait, no boys. I'll see what this is all about. You two wait there."

-h2o-

"Don't you like my singing dad?"

"It's nice Cleo. But I'm more concerned about you. There are two boys down there, who seem, well, a bit smitten."

"They like me?"

"Well that's what it looks like. Why don't you go down there and tell them to go home right now."

Kim comes around the corner.

"Dad, mum wants to see you."

"I'm busy here."

"She said now dad."

-h2o-

Cleo's mum is standing in a group of teenage boys.

"I was just out for a walk and I heard this fantastic voice."

"Yeah, who was that girl singing before, she was incredible."

"Oh yeah."

Don comes down the stairs.

"Out now."

Rikki and Emma also come down the stairs.

"Reckon we're gonna get any ideas out off Lewis?"

"Forget it, he is a pawn person now. Just like the others."

Cleo comes to stand with them.

"I'm popular. Isn't this great?"

-h2o-

The girls manage to get Cleo and Lewis back to Cleo's room, but Cleo keeps on singing, so they have put a headphone on Lewis.

"Lewis, can you hear me? What happened to Cleo?"

"What? I'm sorry I can't hear, but I think I know what happened to Cleo. She is a siren. Just like the mermaids in mythology. They sing to lure sailors to their deaths. I'm hoping this isn't quite that bad."

"So what do we do? Keep her locked up?"

"What? No, that will never work. It's best if we keep her locked up."

"Forget it, he is out of action. We need to figure this out ourselves."

"You don't have to do anything. This is the best thing that has ever happened to me. People like me, adore me. Aren't I adorable?"

"I'll get back to you on that one."

Kim comes in the room.

"Dad says it's getting late and he wants you guys to clean up everything."

"We're busy, kid. Scram."

"He's not going to like that."

They hear from downstairs Don giving orders..

"Don't forget to put everything back in the fridge."

"Oh no, the fridge."

"What are we going to do?"

"Let's just get it done, quick."

They get up towards Cleo.

"Stay here, do not move."

They go downstairs.

-h2o-

"Alright, so does he come out of every electric machine?"

"I think so, although he didn't came out of the TV."

"So what do we do?"

"Maybe poor water on it and freeze it."

"Right, mix water and electricity, I don't think even our enhanced resistance is going to protect us against that."

"With Cleo's help it would be so easy, she could make it wet from a distance."

"Yeah, but I think we're going to have to solve this without her help."

-h2o-

Back in Cleo's room, Cleo starts singing again and sits herself down in front of Lewis.

"What? I can't hear you Cleo."

He puts his headphone down and gets enchanted by Cleo's voice. They come closer to each other and start making out. The other girls come back in, together with Cleo's dad.

"Lewis what are you doing?"

"Hey you, out. Now."

He grabs Lewis by the waist and gets him out.

"You can't protect me forever."

"No, but we can and we will. All night if we have to."

-h2o-

When Emma and Rikki are fast asleep, Cleo gets up and goes downstairs. She picks up the phone, but the electric monster gets out of it and shocks her. Cleo falls to the ground and instead of using her powers, she starts singing. The monster is not effected by the singing and attacks her again. This time she passes out.

-h2o-

Emma and Rikki wake up. They see a bundle under Cleo's blankets and assume it's Cleo, when it's really just a couple of cushions.

"I never thought we make it till morning without something else happening."

"Yeah, thanks Cleo."

Emma gives Cleo's bed a good look and notices how odd Cleo looks. She undoes the blankets and notices the cushions.

"Oh no, Cleo is gone."

Rikki and Emma go downstairs.

-h2o-

Once down, they run into the kitchen and notice her lying on the floor.

"Cleo, can you hear us?"

She wakes up.

"What happened?"

But a knock on the door interrupts them. Emma gets up.

"I'll get it. it might be Lewis."

She gets out and finds herself in a crowd of young boys.

"Oh no."

"Is Cleo home?"

Without answering, she goes back inside.

"Is it Lewis?"

"Sort of."

Don gets downstairs.

"What's going on? What's all the noise?"

He tries to get outside, while Emma makes an attempt to stop him.

"No, don't open that."

"Why? Is that boy Lewis back?"

He opens the door and sees all the boys. But when Cleo appears over his shoulder she gets greeted by an applause.

"Hello everyone."

She starts singing. When she stops, everyone starts to applaud once again.

"Yeah."

Her father takes her back inside.

-h2o-

"Explain young lady."

"They're my fans."

They hear the boys shout 'Cleo'. Cleo's mom and Kim come down.

"Who are all those boys outside?"

"They are Cleo's boyfriends."

"That's it, I'm calling the police."

"No wait. Why don't we negotiate?"

Rikki heads out.

-h2o-

"Alright, three of you can come inside, but that's all. You choose."

All the boys start drumming, but it's Zane, Lewis and Byron who win in the end.

-h2o-

Zane is the first to talk.

"Cleo has a gift. What she needs is a manager. I can do that."

Lewis continuous.

"The world needs to hear her sing."

"Please."

"Absolutely not. I want all your little friends of my grass right now. That lawn has only just been laid."

Cleo comes down the stairs.

"Dad, there is only one thing to do. I could put on a concert at the juice net café for everybody. They would love it."

"Fantastic idea."

"I don't think so."

"Think about it Mr, Sertori, you can't keep Cleo all to yourself. She belongs to the world."

"No, she doesn't. She is my daughter."

"No, she used to be your daughter. Now she is so much more than that."

"You three are off of your collective rockers."

"So the concert is on."

"Leave it to me."

"Cleo! You are not going out there. You three, conference is over. Outside!"

Don picks up the phone, while the three boys stop before Cleo.

"Yeah police, my house is surrounded by teenage boys. Yes I will hold."

He pushes them out. Kim looks out the window and notices them leaving.

"Mum, dad, they're leaving."

"She is right, they are going."

"Where is Cleo?"

The boys suddenly run enthusiastically over to the other side.

-h2o-

The Sertori's, Rikki and Emma make their way over to the juice net café, that's crawling with boys.

"Excuse me guys, sorry, coming trough, excuse me. Stick with me Kim."

"This could get ugly."

"How much more full moon do we have?"

"Not much."

-h2o-

Cleo is getting on the stage. She starts singing, but when the full moon is over, she sounds terrible again. All the boys look disgusted and leave.

"Wait, don't go." She tries to sing, but gives up. "Please don't go."

"I thought they loved me."

Her dad approaches her.

"I still love you and I always will."

They hug.

"C'mon."

But when they try to leave Emma and Rikki interfere and pull Cleo apart.

"What's wrong?"

"There is still a demon to vanquish."

They start running.

-h2o-

They get to the Sertori's house.

"Alright, so everybody knows the plan: Cleo you make it wet and I'll freeze it and we'll see what happens."

"But who is going to open the fridge?"

"On three."

"Alright."

"One, two, three."

They open the fridge together and immediately hide. Rikki makes water from the ice in the fridge and Cleo uses it to make the electric demon wet. Emma freezes it and it stops in mid-air. They get closer.

"Cool."

Rikki touches it and still gets a little shock.

"Great, three mermaids try and still he didn't die."

Suddenly he bursts in a thousand pieces.

"What did you do?"

"I don't know, what did I do?"

"You said, three mermaids try and still he didn't die. Hey, that rhymes."

"You don't think that was a spell, do you?"

"Alright, that would be so awesome, so if we rhyme a little, they die. Why didn't we tried this before?"

"Well, now we can."
