My Little Pony: Spongebob is magic
Fluttershy and Rainbow Dash were following Derpy, trying to stay out of sight. They weren't doing a very good job, mostly because they could hardly stop laughing, but it didn't really matter because Derpy is retarded. Suddenly, a swirling portal opened up before them! Derpy jumped back, tripping over her own hoofs and falling flat on her face. Fluttershy hardly noticed there was a portal to another dimension because she was to busy laughing at a poor retarded pony.
"Holy fucking shit!", exclaimed Rainbow Dash over the sound of Fluttershy's horrendous laughter.
Derpy leapt to her unstable feet and wondered over to examine the portal.
"Oh wow...this is so...cool!", said Derpy, her eyes threatening to overspill her face as they met in the middle.
"You mean the portal to another dimension or the fact that you shat yourself you fucking incontinent mong?", asked Fluttershy.
Derpy rubbed her face with her hoof as she considered this. "Err...The second one!", she said, sounding altogether unconvinced.
"Shut the fuck up you two. I'm the boss here, and I say we jump in and see what happens!", screamed Rainbow Dash. Fluttershy rolled her eyes.
"Of course we're going to jump in you cunt. But, just in case...", Fluttershy said as she turned to Derpy, a warm smile appearing on her face as she viciously headbutted her. She laughed maniacally as Derpy stumbled around for a second before falling into the portal. Fluttershy and Rainbow Dash followed as soon as they'd finished high-fiving.
On the other side of the portal in Jellyfish fields Spongebob, Patrick and Squidward had gathered a small distance away. They looked on in curious fascination as one shit smeared pony and her two "friends" fell through the vortex, shit flowing like an aura through the ocean briefly before dissipating. Squidward tentacle-palmed as Spongebob and Patrick let out a squeal of ecstatic delight and ran towards the magical ponies, who could breathe underwater because they're magic or some shit. Squidward rolled has eyes and ran after them.
Patrick reached the ponies first, coming to a stop before Rainbow Dash, his trusty pet rock in hand. "Hey ponies! This is my pet rock!", he said.
Fluttershy and Rainbow Dash shared a brief look, as if to say, holy crap we found a friend for Derpy, who was struggling to get to her hoofs behind them. Rainbow Dash barely had a chance to turn her head back to Patrick before his trusty pet rock crashed into the side of her jaw, unhinging it and sending her sprawling as a spray of blood flew shot from her mouth to drift through the water before disappearing entirely. Patrick jumped onto his foe and began laying into her, smashing her face over and over with the rock which now had one side coated in the blood of his enemy.
"No! Rocky, stop it!", he yelled, a grim look of determination on his face as the rock crushed Rainbow Dash's eye socket. The other ponies looked on in horror as Rainbow's face was smashed more and more into disfigurement. Fluttershy was the first to react, tensing her strong legs as she prepared to leap to the rescue of her friend.
She leapt. However, as she soared through the ocean towards Patrick Spongebob intercepted her mid leap, crashing into her as they both flew through the water, narrowly missing the portal and flying straight past it to roll across the ocean floor. Spongebob was the first to break off, getting to his feet to confront his rival. Fluttershy leapt to her feet and squared off to Spongebob, the pair circling as they sized one another up. Fluttershy made the first move. She pawed the ground with her hoof and then charged, stopping at the last second and turning as she threw her back legs in to the air to deliver a powerful kick to Spongebob. Little did she know that Spongebob was a master of Karate. He ducked back, deftly avoiding the kick. As her hoofs came back to the ground he stepped in, delivering a powerful kick to her knee as her leg straightened out. Fluttershy screamed in agony as her leg snapped, the bone piercing the skin.
Derpy was watching all of this and it finally clicked that she should help her friend and occasional tormentor. She pawed at the ground, eyes meeting in the middle of her face, ready to charge to the rescue. Suddenly she collapsed onto her knees, her eyes darting down to her throat. She couldn't breath. She couldn't understand why. She stayed upright for an instant after Squidward pulled the his clarinet from her throat, blood pumping into the water around her, before he put his foot to the back of her head and kicked her forwards to die. He wrapped the his shirt around the end of his blood-stained instrument and pulled it through, wiping the blood onto his shirt. He turned to check on Patrick, smiling to himself. Rainbow's legs twitched violently every time Patrick brought the rock down on Rainbow's head, now a gory mess of crushed bone and brains. Squidward walked over and placed a tentacle upon Patrick's shoulder, giving it a gentle squeeze.
"You can stop now, Patrick. It's over."
Patrick's hand stopped mid-swing as he turned to face his friend. His face broke into a grin of ecstasy as he got to his feet and slid his pet rock into his pocket. They walked past the gateway to check up on Spongebob. They watched on as Fluttershy's legs kicked across the seabed. Despite her injuries Fluttershy was able to carry on. Spongebob inevitably overpowered her and now his thumbs were buried deep in her eye sockets as he gouged them out. Her screams had stopped and it was only a few moments more before her futile kicking had also stopped. There was a sick squelching noise as Spongebob pulled his thumbs from her mush filled sockets, the same dumb smile he'd worn all his life plastered to his face as his friends walked towards him.
"Well guys, we did it! We saved Bikini Bottom!", Spongebob cheered.
"Hurray!", Patrick put in.
"Hey guys, we're not out of the woods yet," exclaimed Squidward. "That portal's still up. We have to go back to the town and warn everybody."
And so our heroes set off, to warn their friends and to formulate a plan to stop the tide of evil that was invading their realm.
