CHAPTER 1- Well, I figured that it's been almost two weeks since I posted the final chapter to The Tail of Gravity Falls.

I'm still working on Who's Austin Moon? but I wanted to post at least this first chapter/prologue, just to see how you like it.

I made Linda pathetically angry. I can't see her getting truly P-O'd off about anything. So no grief for that. I admit now that my attempt at her anger was sad.

I don't own Phineas and Ferb or the Little Mermaid. Man, I apparently am really into crossovers right now….

Now, without further ado, Mermaid Swapping!

GENERAL POV

The slamming sound of the door echoed throughout the house, creating an almost ringing in the ears of everyone sitting in the living room.

The door itself practically fell off of its hinges from the force at which it had hit the doorframe, the metal knob vibrating violently.

Candace's shoes barely made a sound as she strode across her carpet and flung herself face down onto her bed, burying her face in her pillow and struggling to not cry.

The early August sun beat into her room with un-relentless heat, finally making the girl stand up and fling her curtains together to keep the suns glare from entering her room.

"They just don't ever see it," she whispered to herself, sitting heavily on her bed and drawing her knees up to her chin.

Every time. Every time the boys had some stupid invention, her parents never saw it. Sure, she had tried giving up busting several times, but she just couldn't do it for long. And it normally didn't bother her when her mother didn't see the inventions. She would just try next time. But this time? This time Linda had gone too far.

Candace shuddered and buried her head in her arms. Her mother was definitely under stress, of course; Lawrence's birthday was in a week, and they wanted to make it super special for him.

Candace sighed and turned her cheek to the side, laying it on her arm. Her mother's words had hit her like a hammer:

"Young lady, your brothers have never made, and never will make any of this crazy stuff you constantly lie to us about! I don't want to hear it from you ever again, Candace! Don't bother speaking to me until it doesn't relate to your stupid lies!"

Candace gulped and shook her head. She had never heard her mother be so harsh before, probably because her mother never was harsh. Stress or no, she shouldn't have snapped quite like that.

The sound of the door creaking open made Candace glance over her shoulder, expecting to see Phineas or Ferb.

Instead, a teal platypus wearing a brown fedora stepped into her room, his eyes worried. Candace quickly brushed a tear from her cheek and turned around on her bed as the secret agent shut the door and walked over to her, leaping onto the bed with ease.

"Hey, stupid, you better be careful. Someone might see you," she said, trying to laugh.

Perry gazed up at her, his eyes searching hers.

"Are you ok, Candace? I got back from my mission in time to hear what Linda said to you," Perry chattered softly, removing his hat and sitting down on the bed.

Candace sighed and rubbed her eyes. "I'll be ok, Perry. Sometimes…sometimes though, I wish I could just get away from home for a while, forget everything and just relax."

Perry gave her a small smile and patted his owner's hand. "Don't worry. Your mom means well, Candace."

Candace sighed and gave the platypus a tight hug. "I know, Perry. I know," she whispered as she laid down for a nap.

The platypus squirmed out of her grasp a few minutes later and tiptoed quietly out of the teen's room, shutting the door softly behind him.

The ocean practically boiled as the palace gates were slammed shut by the angry, red headed teenage mermaid currently swimming away as fast as she could.

Said mermaid flung herself into her bedroom and buried her head in her hands, curling her tail under her as she started crying.

A small yellow and blue striped fish swam in after her quickly and rested lightly on her bed, staring up at the mermaid in worry.

"Come on Ariel," the fish said softly, brushing a gentle fin against the girl's shoulder. "It's not that bad."

Ariel looked down at Flounder, her eyes matching the color of her hair. "Flounder, you don't get it. Daddy said that he never wants to hear about humans again, no matter what I have to say, and that I shouldn't even bother to talk to him until I've forgotten all about them."

Flounder winced and looked away out the window.

"How can I forget about them, Flounder?" Ariel asked, pulling a pillow to her chest and hugging it. "They're so fascinating!"

Flounder sighed and turned back to his friend with a sympathetic smile. "I know you think humans are cool and all, Ariel, but your dad is only trying to protect you," he pointed out.

Ariel chucked her pillow across the room, watching it hit the wall and sink to the floor. "Well maybe I want him to stop!" she cried, throwing her arms in the air and sending her hair flying in a million directions. "I'm almost sixteen, Flounder. I can look out for myself."

Flounder cocked his head, in turn cocking his whole body so that he spun in a small circle. Righting himself, he spoke. "Ariel…"

"Flounder," Ariel said softly, holding up a hand and shaking her thick head of hair. "I just…I want a break from all of this. You don't get it. I'm pretty sure no one in the whole world gets what I'm going through right now! Dad doesn't believe that humans aren't all evil, and I just can't prove it to him!"

"Come on Ariel," Flounder said, nudging the young mermaid gently. "There's probably someone out there who knows exactly what you're going through. Or…at least, understands it better than I would."

Ariel sighed and leaned back on her bed with her arms crossed, her hair covering her face. "Maybe," she said softly. "But still. They probably don't go through this kind of thing every day."

Flounder frowned and swam over to Ariel anxiously. Ariel sighed and turned her head away from her longtime friend.

"I just…I need a break. Can you…can you leave me alone, Flounder? Please?"

Flounder gave Ariel a small smile. "Sure, Ariel. See you later, ok?"

He didn't get a response, and so he turned and swam away quietly, letting his mermaid friend fall asleep in the comforts of her own bed.

Ah, unknowingly having the same issues always amuses me. And I told you Linda's anger was pathetic...Triton's never was really about anything significant...yeah.

I know it's short, but it's kind of a prologue/first chapter. The rest of the chapters will be my usual length.

NOTE: Pretend that the movie The Little Mermaid has not happened yet. There is no Eric, no Ursula (well, there is, but not in this story), no Max, nada. None of that has happened yet.
