"Yay! This, will, be, EPIC!" Mikey grinned. He was going to pull off a prank, nothing to difficult, in fact, the simplest one on his list: he was going to splash Donnie with cold water, before squirting him with paint. Yup. This prankster wasn't on high level today.

Mikey cheekily grabbed a bucket and filled it with water. Suddenly, the door opened and Casey popped his head in. "Yo dude? Whatcha doing? Another prank?"

"Got that right, Casey." Mikey laughed. "In fact, it's on your least favorite turtle: Donnie Hamato!"

"Sweet!" Casey smirked. "Mind if I help?"

"No problem." Mikey let him in on the plan.

~ time skip~

"Set up?" Mikey whispered, positioning the bucket on the door. Casey gave a thumbs up. He had filled a water gun with liquid paint (to ensure it didn't get stuck inside lol). Casey hid beside the door.

Mikey could hear Donne inside rambling off to idk who about something. How wrong he was to think it was metalhead.

"Okay, so I'm gonna go..." Mikey didn't hear the rest of the sentence. His mind was too busy submerged in excitement.

Just then the door open and the bucket fell down. Without looking, Casey pressed the trigger and paint shot out and drenched the "turtle". Mikey and Casey chortled happily, when suddenly someone (who sounded very much like April) said, "WHAT THE HECK?"

Mikey swore that Casey could have fainted. They had targeted the wrong person. Donnie was talking to April, not metalhead!

"Oops..." Mikey grinned as he dashed off. Casey was left behind and he stared at April sheepishly.

"Sorry?"

"You are so dead, Casey Jones." April fumed, as she and Donnie (who had just stepped out of the lab), watched Casey run after Mikey. Donnie turned to look at April. "You wanna go get a shower?"

"That's not the only thing I would like to get." April seethed. She turned to Donnie. "I would like to get revenge too... "

"... with you."

~time skip~

"What should the revenge be?" Donnie asked, his mind cooking up silly and drastic revenges to "kill" Casey and Mikey. April grinned. "They don't call me the queen of the pranks for no reason! I'd say we do this..."

~time skip~

Both had settled on a simple yet devious plan of revenge for Mikey. April was to set up some flour above the door using a rope. It was classic, but worth it. Mikey would trip and the bag of flour would be released. However that wasn't all. They were to-

NO NO NO not to be carelessly revealed here. So read on to find out!

Just as April stepped off the ladder, Donnie whisper-cried, "Incoming! Mikey coming!"

April and Donnie ran off with the ladder. (Phew.)

Just as they leapt over the couch, there was a "whompf!" Sound, the sound you get when flour get dumped onto the floor (it's a pretty hilarious sound I must say XD). April started cackling loudly, and Donnie soon laughed along. They were met with a enraged Mikey who was covered in flour ANDDDDDD *drumroll please* PIGEON FEATHERS!

"WHAT!"

They didn't wait for him to finished, instead they ran off to plan the next revenge: Casey.

mEaNwHiLe

Casey was lying on Raph's bed, reading one of his comics. Suddenly, Mikey barrelled in like a turtle with its tail on fire.

"CASEY!" Mikey panted. Casey stared at him and laughed. "Dude, why are you covered in-"

"SHUDDAP!" Mikey fumed. "Donnie and April plotted revenge on us!"

"What!" The last thing he wanted was for Donnie to win April's heart. And that was what happened. Casey ignored Mikey's warning of further pranking, and stomped out of Raph's room.

(Anyway let's just say Raph wasn't really happy there was flour all over his room.)

~time skip~

Casey looked for April EVERYWHERE. And when he meant everywhere, he meant EVERYWHERE in the lair. He searched high and low, the bathroom, kitchen cupboards (yes April is actually really small no offense.) and even the bathroom. One place he didn't search though, was Donnie's lab, which was exactly where April was.

Bad luck, because that was ALSO where they were planning their next sneak attack of revenge.

April contemplated on using the same, but Mikey would be on the lookout. So she and Donnie decided to go buy some fake rats and also some mealworms. I mean, no matter how un-afraid of mealworms you were, one crawling around in your food just means one word: YUCK!

April went to buy the mealworms, while Donnie pleaded Mikey to make him a bowl of chicken soup. Knowing Mikey, he would probably put laxative inside, thinking it was for Donnie and Donnie himself. To them, this was just added bonus. Casey was going to get a black cat.

Snickering, Donnie received the bowl of soup, which Mikey claimed to be "very free of toxins". Donnie didn't believe him of course.

Grinning evilly, he met April at the manhole cover. "Got the worms and fake rats?"

"Yes. Got the soup?"

"Nice and delicious." Both laughed, when April said, "I actually went to catch real rats."

~ time skip ~

This time the perfect prank would be pulled using the kitchen. Donnie placed the bowl there and getting Leo to write, "For you, Casey~" Casey would never recognize the handwriting.

April dropped the mealworms into the food with a plop and Donnie stored the rats in a cupboard, which both knew equally well that Casey would open it to get pepper. All was perfect.

~ time skip brought to you by More Time Skipz ~

Casey walked into the kitchen hungrily. He spotted the bowl of chicken soup.

"Huh..." He peered at the note. "Mikey must have left this for me!" Nope Casey, Mikey cooked it, but he certainly did not leave it for you...!

Casey sat down and sipped the laxative-ed soup. "Yum. But not enough pepper..." As Donnie predicted, he stood up, walked to the rat-ed cupboard and yanked it opened. The most-are-very-much-alive rats tumbled out, making him screech and lunge for his precious soup. "NOOOO!"

After a while, all the rats scattered away, leaving some dead rats (who died due to lack of oxygen lol) and a freaked out Casey. Sighing, Casey plonked back on his seat after making sure to wipe the rats off it. Then, he drank the soup greedily and at the bottom he found a... Mealworm. Yes.

"EW!" Casey screamed, attempting to barf out the soup, but failed. Well, suit him, it was laxative-ed too.

Casey threw the mealworms away and ran out of the kitchen, goosebumps forming on his neck.

What Casey didn't know was that April had fed him twice the average amount of laxative for adults and that he was going to probably have a hard time. Donnie considered hogging the toilet but April stopped him. He wasn't some magical creature who wouldn't die if he didn't go to the toilet despite having faeces desperately trying to rush out.

A few minutes later, the quick laxative took effect. Casey rushed to the toilet, but to his dismay it was locked. SOMEONE WAS INSIDE! And since Donnie and April were in their rooms laughing their heads off, Leo and Raph were sparring with Master Splinter meditating beside them, there was only one person.

Mikey.

Alternate ending

Yes, Mikey. Mikey, the one who had teamed up with him to get Donnie. That Mikey.

We can certainly say karma has come back to Casey, although it wasn't really his fault. Maybe Donnie and April were too harsh on him? Mikey should have gotten the real karma. Anyways, it was Casey's fault that he had joined in on Mikey's prank.

Let's just say he spent 1 hour in the toilet pooping his guts out...
