DISCLAIMER: I own nothing!

(note: in both Kim possible and h2o they have graduated and are the same age. also with Kim possible the whole alien thing didn't happen... sorry just didn't want to introduce aliens into h2o) whatever on with the summary!

Kim Possible and Ron Stoppable, fresh out of school need a break that the pressures of saving the world while trying to figure out what the future holds has brought upon them. So when Kim gets an offer from an old friend to stay with him in Australia her and Ron head for the adventure of a life time to uncover the mysteries of the secretive island off the coast, will they find out more than intended or will the mermaid's secrets stay safe?

"Bye dad! bye Kim!" Cleo Sertori stated with enthusiasm shutting the door as her father and sister pulled out of the driveway.

This was going to be the perfect week, her father, sister, and stepmother Sam would all be going to a fishing conference out-of-town about some new bylaw that has to do with coast regulations... or something she wasn't really paying attention when her father had brought up the subject all she knew was she had the house to herself for 2 WEEKS!

It took awhile for her to convince her dad to let her stay home alone but it was worth it. Kim had wined about having to go but Don Sertori knew well enough than to leave the sisters home alone together, the two would bite each others heads off!

Cleo's Motorola flip phone played the song "No ordinary girl" by Kate Alexa as a picture of Lewis illuminated the screen. "Hey Lewis!" Cleo smiled giddily at the thought of her boyfriend "what's up?"

"Oh nothing much I just wanted to remind you the full moon's in a couple of days" "Thanks, I've got everything sorted." Cleo said mater of factly it had been a long time since the moon had affected the three mermaids but in the back of her mind she was still a bit nervous, getting moonstruck would put a damper on her weekend

"You sure? You got the house to yourself, right?" "Yep," Cleo responded to the question she'd heard a million times before "Sam's in meetings all day so she's catching a later flight. But other than that all good."

The two chatted for a while. Since Lewis was taking a few courses in Australia the couple had spent time together non stop. Cleo heard a faint beep on the other end of the line

"Uh Cleo," Lewis stammered "A couple of friends from the states just emailed me back I was hoping they could come to visit. Would that be alright? you know with the full moon in a couple of days and all, it might be bad timing?"

"No Lewis definitely have them over, I'd love to meet them. The girls and I can handle the full moon." Cleo said with a smile on her face. Getting Lewis to believe her was one thing, believing it herself would be a whole lot harder. "Ok... I'll email them back."

"But Lewis, isn't it kinda short notice? How will they find a flight in time?" As they spoke Cleo was running the whole scenario over in her head it didn't make since! it would be at least an 18 hour flight! There is no way they'd make it on such short notice!

"Oh don't worry," Cleo could practically feel Lewis smirking through the phone "their sort of what you would call... world travelers."

Awhile earlier in the small town of Middleton, Colorado...

"All I'm sayin KP is we need a cute couple name!" Ron Stoppable pleaded his case, But his girlfriend Kim Possible was less than pleased

"Ron we already have a couple name, it's Kim and the bathoon standing next to her!" The pink naked mole rat which was hidden in the pocket of Ron's cargo pants burst into fits of laughter at the thought of the pet name Kim's arch nemesis had blatantly given to Ron.

"aww..." Ron whined "That may work for Draken but I resent being called a bathoon! OOH! I've got it! how about we call ourselves *Rim*!"

"Uh... yah... no." Kim responded giving Ron her *REALLY?* look that she had perfected over years of knowing him. The naked mole rat shook his head letting a sound out that said he didn't approve of the so-called "COUPLE NAME" "Argh! not you too Rufus!"

"Face it Ron there is no way on god's green earth we are ever calling ourselves that!" Kim couldn't help smiling. She was so out of her boyfriend's league, that's what was so reassuring.

"Well the dynamic duo is taken so..." Ron began to swivel in Kim's pink desk chair like it was a ride at the fair. Before Kim could think of a clever reason why they DO NOT need a couple name a box blinked across her computer screen indicating she had an email.

"who's it from?" asked Ron clearly glad to get away from the battle he was losing. "It's from Lewis, you know the guy we met while researching collages in San Diego? He's invited us to visit him in Australia."

"WHAT! Let me see that!" said Ron pushing his girlfriend out-of-the-way so he could read the email.

Hey guys, long time since we've spoken I just wanted to see how you're doing and to ask you if you'd like to stay with me in Australia for a couple of weeks?

I've got a lot of room since my brothers moved out and my parents are cool with it.
