Oh and most of the music put on this story WILL belong to Disney, so their music belongs to them. I just tweak the lyrics to match the theme better.

It was one of those days that Rarity had to do the dishes. Sometimes, Rarity wondered how much King Sombra eats, and how he can chew on those crystals without his teeth cracking. Sometimes, she'd feel frustrated that he eats so many crystals, which could be used for decoration, buildings, and clothing.

"Perhaps," Rarity muttered to the dishes, "he made the crystal ponies slaves, not only for power but for his own food. It's also a wonder how these crystals don't scratch the plates."

She stood there, as she scrubbed and wondered, "Perhaps these plates are diamonds?" with a closer look, they weren't, which baffled her even more. "Why does everything have to be so mysterious? There's even a washing machine and a dish washing machine that no pony has even heard before!" At the mention of dishes, she stacked the plates in the machine.

All the sudden, the sponge turned into a rubber duck, and the plates into Frisbee. "Huh?" Rarity dropped the once-sponge in shock. Then the rubber duck turned and looked at her!

"Hello! Hello!" it squeaked, "I'm duck! What's your name?"

"R-Rarity?" she stammered.

"Hello Air-ity!" It said, bouncing up and down. "I'm so new! Do you like bread? Why are you so huge? What is that thing?" Then the duck bounced out of the room.

"He-hey! Get back here!" she cried, hurrying after the runaway duck. To her shock, the torches were flickering between, cotton candies, flashlights, then back to torches. The floor was spinning like a hurricane as the duck leaped around.

"Get back here, now!" Rarity yelled, struggling to keep her balance. The rubber duck bounced to her, and squirted water at her face. Then it squeaked in laughter and bounced away. The unicorn's face turned red and the floor suddenly dropped. She screamed as she fell, and then landed on a twisting slide.

"Help!" Rarity cried as she flew across the air at the bottom of the slide. To her amazement, she landed on a cart that looked like King Sombra's head.

"Prepare for a takeoff. Please buckle up," the cart said in a demonic voice.

"Wait-what?" Rarity yelped as the cart automatically buckled and zoomed downward on the rails. It then swung right, tipping the cart in the same direction. Then it zoomed up, circled around, then went upside down as the victim hung on, screaming with her face deadly pale.

The duck again met her as it bounced into her cart. "Fun right?" it said cheerfully. The unicorn's clung on tighter as they passed the sign that said: "Closed due to random jokes."

The cart swept down, then at full speed upwards, and flew off the rails. Rarity screamed as the cart flew through King Sombra's room, who was currently taking a nap. His sleep disturbed, he woke up to screams and laughter. "Not this time of year again!" He groaned, ducking his head under the sheets.

The cart forcefully opened the doors to the stairs and bounced loudly as it clattered on the steps. As Rarity reached the basement, the cart stopped and said in the same previous tone: "Thank you for riding," and then it melted.

"Noooooooo!" The duck wailed, squirting Rarity as it did in the process. The unicorn, enraged again, tried to catch the duck as it bounced away, barley escaping her grasp.

"Come back here you… you demonic piece of rubber!" Rarity screeched, galloping full speed. She ignored a group of shadows quivering, their teeth chattering, eyes wide and they struck close together as she passed by.

Rarity finally caught the duck as she pounced on it, but it had a few more surprises for her. It caught on fire and turned into a plastic flamingo. Her eyes watered and jumped ten feet into the air as she let it go and howled in pain. The flamingo laughed manically as Rarity hopped around, whimpering. Rarity picked up a nearby Frisbee and chucked it at the flamingo. It stopped laughing and swallowed the Frisbee whole. To both of their surprises, a pillar fell from the ceiling with a red button.

They both glared at each other, and made their way to the pillar. Time itself seemed to slow, as Rarity shoved rubber duckies out of the way and the flamingo dodging trees.

Rarity slammed her hoof on the button, just in time to beat the plastic bird. Pinkie pie flew in as confetti busted out of nowhere. The pony polka music started as she danced around, her mane releasing balloons. "Whoo hoo! 'Tis today, April Fool's day!" Pinkie cheered as she reached over to shake Rarity's hooves and the flamingo's wings.

Then pinkie sang the wrong lyrics to the song currently playing. "Ohhhhh! Yippie, Hurray! We know who's a fool today! Ohhhh! Yippie, Hurray! The bird is a fool! For years he mocked ponieeeees! If you're a sleeper he'll BLAST the horns and run! Perhaps a dasher, he'll give you an anvil for shoes! Becaaaaaaaaaaaause, he's the master of April's Fool! Hail him, for he's no name! But not today, for she has won! Rarity! Raaaaaaaaarity! Shame on his cow!" Pinkie reached her full volume as she finished the song, confetti busting out of her hair. "Hurray!"

"How did you get in, Pinkie?" Rarity asked as the bird hung his head in shame.

"Oh, let's just say-" the earth pony said with a wink.

The pink pony bounced to the castle, humming heartily. As she reached the barrier, she was sent back a yard away.

"What?!" she cried, outraged. "Who dares to keep me from seeing a friend? Oi! Rosie do please come!" Pinkie looked directly at the screen, breaking the fourth wall as usual.

An earth mare appeared from thin air. She had long, silky red mane with bangs, mysterious blue eyes, and cream-colored fur. Her cutie mark bears a pencil making a squiggly line. "Yes Pinky?" she asked.

"Oh please let me in, author!" Pinkie begged.

"Well-"

"Pul-lease?" The pink pony was now using her puppy eyes.

"Oh, fine, fine." Rosie sighed, giving in to the eyes. She pulled out a notebook and a pencil out of nowhere. She set the book down and pencil into her mouth, wrote a few lines. "There, now you can enter."

"Thank you, oh thank you!" Pinkie said, trotting through the barrier.

Rosie turned and broke the fourth wall barrier with a wink. "Happy April's Fool, everypony! Don't forget to have a great Spring break if you have one in your area!" Then she vanished, leaving behind a bit of unknown magic, and "bippy bopply boo."

Author's Note:

No, I do not have red hair! Also, this chapter was fun for me to write.

Announcement: another story is coming soon! It will not be My Little Pony fanfiction though. The one coming in the summer will be. See ya later, Alligator!

By the way: I love roller coasters! Especially California Screamer that's in Disney land, California (duh) and California SeaWorld's Mantle! Ride those someday if you love the thrills! Poor Rarity though…

Yes, I do know it's not April Fool's Day-yet.
