Voila! This is the third story by me, Gamer21, the Yoshi Experiment! This'll be interesting!

"What on earth are you doing?" That was the question Falco Lombardi posed to Luigi when he leaned a ladder against the wall and had a pulley and a bag of cement laying off and to the side. Luigi was against a door decorated with a green polka-dot egg, hooking the pulley in place.

"Hush!" Luigi hissed. "I-a will make-a Yoshi the laughing-a-stock of the day with-a my newest-a prank!"

"I thought Yoshi was off-limits, though."

"Oh, stow it! He-a won't-a know what hit-a him!" Luigi had tied the cement bag onto the end of the rope and strung it through the pulley. "Now-a get me my pineapple-a, ho!"

"I ain't any frickin' butler of yours," Falco grumbled, but did as he was told, and in a few minutes brought back a large juicy pineapple from the kitchen and ran off, leaving Luigi to ponder in his wake.

Minutes later, Falco was seen strolling down the great, opulent stairwell of the Smash Mansion, pulling out his blaster and performing several impressions of that spy, James Bond, as he wormed his way towards the lounge on the second floor, where Pichu was playing the new Baten Kaitos game. "Yo, Pich! How's life?"

"It dealt me a hand, and it gave me a fun idea!" Pichu squeaked.

"What did it say?"

"It says, 'Prank Yoshi today by pouring crushed laxatives in his drink during lunch.'" Pichu showed him a closed film holder and began to sing a weird song that caused Falco to freak.

"It's a fine pranking day,
And as balmy as May,
And all the party poopers from the Mansion are gone,"

A clatter of various toys being spilled onto the floor and a 'Dammit!' from Falco drowned out the next lines, but as Falco Lombardi left the room, he heard Pichu's triumphant assertion:

"And we'll all go a'pranking today!"

Falco had now calmed somewhat as he made his way down another flight of stairs and was strolling in the general direction of the cafeteria. However, his foot landed on a blue cat's-eye and Falco began to feel his weight shift. His reflexes had shot out and grabbed the nearby railing before his face exchanged pleasantries with the floor, however, and saved himself from an embarrassing result. He glazed his surroundings and noticed a familiar blue-haired mage scatter miniature glass spheroids onto the marbled floor.

"WHOA! What are you doing, Lilina? I never figured you to be the jokester..."

"Well, I woke up feeling a little mischievous today." Lilina had a large, stupid grin plastered on her face when she whirled around to face Falco. "So I decided to steal Young Link's marble collection and scatter it on the floor! It will make anyone who walks by slip up!" By the look of it, she had finished spreading out the marbles all over the floor when Falco came by.

"When I said Young Link lost his marbles yesterday, I didn't think I was right..." Falco rubbed his chin thoughtfully as he recalled an argument between himself and Young Link over who was stronger that had culminated into a food fight.

"Oh well, see you later!" Lilina said as she ran off, but stepped on one of the marbles she had scattered and slipped, landing face first on the Italian marble flooring. "Ouch...mommy..."

"Right..." Falco muttered as he made his way to the cafeteria.

Stretching his little green arms as far as they would, Yoshi was stretching to help himself loosen up and ready himself as he yawned. "This'll be a good day!" He walked over to the door when a deliciously luscious aroma tickled his nose. Realizing it was a pineapple, he rushed out the door with his mouth overflowing with drool and yelling, "Yay! Pineapple!"

"Haha, that's-a one for-a me..." Luigi grinned from the shadows when the cement bag exploded on impact, sending a flood on white powder enveloping Yoshi and confusing it. Poor, poor Yoshi stumbled around blindly...and was shown the railing of the balcony his room was built into as he fell over the railing, squeaking in a panic as he did. "Oh-a shit, that-a wasn't supposed to happen-a..."

"YAAAH!" Yoshi screamed as he plopped onto the stairs below him, which was only 10 feet below him. "YAY! I'm not dead!" He then wandered downstairs into the main hall and slipped all over the marbles left oh so courteously by Lilina. He slipped and slid right into Samus, who was carrying a tray of food, and watched in horror as the food splattered all over her Power Suit, leaving stains of all kinds all over the poor green dino.

"Yoshi! What the hell is wrong with you? And why are you covered in cement?" Samus scolded as she made a futile attempt at cleaning her Power Suit.

"I'm sorry..."

"It's okay, but how will I-wha!" Samus had stepped on another marble and landed headfirst onto the floor, muttering strings of curses as she lay on the floor. "Owwie...I vood suchesht chat voo waff uf in zee showersh..." she mumbled.

"Good idea..." Yoshi remarked as he stepped into the shower room.

Sometime later, the noon time found Yoshi quietly eating lunch with Kirby and Jigglypuff, who was discussing the local scandals of the day, beginning with this morning's prank.

"So, do you have any idea who did it?" Yoshi asked, waving his fruit tart around eloquently.

"I heard from Falco that Luigi was the one who booby-trapped your room." Kirby was mulling over a chicken leg and made a face when he bit into it. "Yich, I think they overcooked this one..."

"That's way I order fruit tarts for lunch..." Yoshi answered.

"Yes, but they aren't anywhere as good as this Pokè Block..." Jigglypuff bragged.

"We're not Pokèmon, for goodness' sake. How do you expect us to enjoy it if it tastes like crap to us?"

"Oh, shut up." Jigglypuff waved Kirby off before he could say anymore.

"That Luigi..." Yoshi was fuming and said, "If it's because of the Noodle Incident, I told him that I had nothing to do with it."

"Yeah, I always thought that he was a little shady...what of the other pranks?" Kirby asked. "Did Falco say what would happen concerning those?"

"He said Lilina had something to do with the marble incident."

"So much for the 'sweet, delicate mage' crap..."

"Yep..." Yoshi bit wholeheartedly into the fruit tart and added, "I hope things don't get too crazy around here..."

"Like that?" Yoshi followed Kirby's finger to where Crazy Hand had barged into the reception hall, and watched as he twitched, bitch-slapped and sometimes threw various things out of his path, whether it be a table, a chair, or a screaming Smasher. He was yelling obscenities and the like while he made his way towards the front of the room.

"Speak of the devil..." Yoshi gasped as Crazy Hand began to mutter incoherently.

"Gblixl mnguh gbolrgl auhdnfj muijnd."

"Did anyone get that?" Kirby asked the others. After receiving a series of no's from the other Smashers, he yelled, "What did you say?"

"Doesh anyvaughn vant their yoohoo painted g-aaaa-ld?" Crazy Hand yelled in a Dutch accent.

"How about no, you crazy Dutch bastard?" Dr. Mario yelled.

"Hey, that's from Goldmember!" Pichu yelled excitedly.

"..."

"Don't give us that 'dot dot dot' crap! You're not the 'dot dot dot' king!" Pichu yelled accusingly at Crazy Hand.

"Damn you..." Crazy Hand dragged himself off the stage up front and sulked out of the cafeteria, letting the other Smashers alone to their lunch.

"What the hell was that all about?" Yoshi asked as he finished his fruit tart.

"Who knows?" Kirby threw his hands up in exasperation as he finished the rest of his chicken.

After a long, grueling training session in the gym on the 3rd floor, Yoshi was wiping sweat off his brow and using his towel to rid himself of sweat before tossing it down a nearby laundry chute. He made his way over to the cafeteria, where they were serving fruit smoothies. Helping himself to a pineapple-mango, Yoshi stirred in some ice and a bit of protein powder before sitting down at a table to rest.

Pichu soon joined him with a chocolate éclair and a carrot-ginger smoothie of his own. "How's life, Yoshi?"

"Exhausting." Yoshi had wiped some more sweat off with a napkin and asked, "So now what?"

"Nothing too much." Yoshi took a sip of his smoothie and asked, "How's the wife and kids?"

"I don't have a wife and kids...at least, last I checked I didn't..."

"Just messing with you. So what news is new today?" Yoshi asked Pichu, who was stirring in some rock salt. "Hey, is that good?"

"Yeah!" Pichu said.

"Let me try some!" Pichu grinned in a sinister manner as he pulled out the film holder with the crushed laxatives and swapped it with the canister of rock salt.

"Here you go!" Pichu said, handing Yoshi the crushed laxatives. 'Feel the pain of diarrhea, as I revel in your misery...make it more "I sit and laugh! Hahaha!" ...oh, forget it, I'll think of it when the time comes.'

"This should be good..." Yoshi said, unknowingly pouring the laxatives into his drink and stirring it. He then wondered, "Where does rock salt come from?"

"..."

"..."

"..."

"..."

"...right, best now to think about it too much." Pichu said to shatter the awkward silence. "Are you going to drink that or what?"

"Geez, don't have a cow..." Yoshi said as he gulped down part of his smoothie.

"Yes! HAHAHAHAHAHAHAHAHAHAHAHAHA!" Pichu laughed. "I got you!"

"What are you talking about-oh shit..." Yoshi muttered as the toilet began to beckon. "What did you put in my drink?"

"Oh, just something I call 'crushed laxatives'." Pichu laughed gaily. "Now feel the pain of diarrhea!"

"Haha, Yoshi got dissed!" Ganondorf chimed in. Suddenly the whole Mansion exploded in laughter at Yoshi, Pichu's laughter being the loudest. Shuddering, he ran off towards the rest room, but not before yelling, "A plague on your houses!" Laughter echoed off the walls. Everyone laughed for a full five minutes until they were too tired to laugh anymore. That's when Mario asked,

"I-a hope we-a didn't overdo-a it..."

"He can take a joke!" Pichu said. "Can't he?"

Yoshi was in the restroom muttering and wishing for revenge, when a thought hit him. How about they get a taste of their own medicine? Yoshi went back to the restroom, but made a triumphant assertion:

"They will see that I am superior at pranks! I'll get them all...you'll see!"

Poor Yoshi, he was being betrayed by three Smashers. How does he plan to pull this revenge off? Well, find out in the next chapter! Now review, folks!
