It was a dismal, overcast day in ponyville, and Rainbowdash was tired from a long day of working to make it a dismal overcast day. She wanted nothing more than to lay on a plush cloud and take a nice, long nap. She grabbed a chunk of cloud from the brewing, storm fluffed it a little inbetween her hooves, and laid down on it. She closed her eyes and relaxed. Work had tough today but ponyville needed a storm. She was about to fall asleep, when she felt a powerful shock run through her body. She slept up and leapt up in pain. She looked around in confusion.
"Huh, what, who's there?" She asked to the open sky. She searched her immediate surroundings for somepony to blame for this infringement of her naptime.
She was about to settle back down on her cloud, but when she set her hooves on it a jolt went through her leg. She jumped back off the cloud. "Seriously who keeps doing that," she said to nopony. She saw a movement in the corner of her eye. She looked down to see that her napping cloud had moved to the right.
"Hey!" She shouted at it, "who's in there." The cloud dashed off into Ponyville. She followed it as fast as she could. Her quarry soared over the roofs of her home town. On any other day she could have caught it with speed alone, but today she was just to tired from a long day of storm building. She would have to rely on her wits alone to defeat her bizarre adversary. She took in her surroundings. She saw Ponyville library off to left in the distance. She smirked, she knew how easy it was to crash into that building. She came up on the clouds right in an attempt to force it into the wall of the library. The cloud headed strait for the window of the library, and Rainbowdash knew Twilight wouldn't be happy about having her window smashed. But it was certainly for a good cause. Much to her surprise the cloud dispersed upon hitting the window, but the window remained intact. "Wh-" Rainbowdash managed to stammer just before crashing through the it, and into Twilight's how.
Twilight leapt from her chair, "What's wrong, is Discord free, is somepony dead? Spike get the first aid kit and the book about how to use first aid kits effectively." Rainbowdash was lying mostly unharmed on Twilight's floor shocked and befuddled by what she had just gone through, as Twilight took a roll of bandages from her first aid kit.
Nimbus flew as fast as he could away from the mad-mare who had, only minutes ago, tried to nap on him and then brutally murder him. He floated threw the empty streets of Ponyville warily, in search of safety. He drifted past a busy marketplace. Several ponies looked at him with peaked interest. This staring lasted only a few seconds until one pony spoke up. "It looks like the weather team missed one," He said as though he intended this statement to be a joke, although Nimbus, along with everypony in the street, was unsure how it could have been remotely funny.
A Pegasus approached Nimbus after the awkward silence that followed the awful joke. Nimbus saw how large the crowd was and he knew he could not run from all of them. He had to do something, and fast. Acting on his cloudy instincts he shot off a lightning bolt. The bolt went far off its intended course, to hit a random pony in the crowd. This was accompanied by a loud, pained shriek followed by low, drawn out gurgling. Despite completely missing his target, Nimbus had still created a substantial distraction. Many ponies gathered around to see if the pony was even still alive. Nimbus took this opportunity to fly away from the market as fast as his fluffy body could take him.
He flew until he was exhausted, he knew he couldn't keep flying like this for much longer. He had to find a way to hide among the residence of ponyville. He looked around and he saw a large sign in front of a carousel shaped building that read: carousel boutique. He had no time to lose.
Rarity stood next to her poniequin. She was hard at work on a new dress, when a rock hit her window. It barely hit it with enough force to crack it.
"What in Equestria is that?" Rarity said as she was about to go outside to see who was pathetically trying to break into her place of business. She was about to open the door, when there was a loud boom and a flash of bright light as the window shattered and her poniequin exploded.
Rarity could only stare in confusion as a dark storm cloud entered workshop, grabbed a sewing machine, and spent five minutes dragging it through the destroyed window. It then dashed back in and grabbed a large piece of purple cloth and left for good.
It took him a few hours, but Nimbus had finally sew together what he thought was a reasonable pony costume. In reality it was a a scarecrow like mass of cloth with large obvious seams that would have made the previous owner of the cloth weep. He flowed into it threw the mouth. To his great irritation, he could not move any of the felt pony's extremities, and would occasionally bump into an object and drift off coarse. He looked like something from a low budget horror movie, but it would have to do.
"WHO THE HAY ARE YOU!" Came a voice. This was probably the owner of the house Nimbus had broken into in order to plug up the stolen sewing machine. He floated past the pony to the door as fast as he could. Which was not very fast at all considering he kept bumping to the pony's belongings and even bumped into the pony, once.
The pony Stood dumbfounded in its home. It went over to the phone. "Hello police, I think Twilight Sparkle went off the deep end again."
Nimbus drifted around the streets of ponyville in his new disguise. He drew a few odd stares from the townsflok, but was otherwise left undisturbed. He felt himself bump into somepony.
"Hey watch it," came a voice from above him. He shook with fright at the sound of that voice. Hooves grabbed him and held him in place. "Have you seen a-," Rainbowdash paused,"wait one second." Rainbowdash forced the ponies mouth open to see it full of clouds. "You!"
Nimbus burst forth from his pony suit and flew through Rainbowdash. Her momentary confusion allowed him to get a head start. "Hey!"Rainbowdash shouted before speeding off after Nimbus, "you can't get away this time." They flew over ponyville as though they were reenacting the previous events of the day. Once more Rainbow managed to force him off coarse, but now the window was destroyed from where Rainbowdash had smashed through it. Nimbus hit the window frame and hit the wall on the other side of the library.
The ponyville police and a few members of the royal guard were crowded around the building. "Twilight," Shining Armour said as calmly as he could, to his sister, "the ponies have agreed not to press charges for you breaking into their house, just please come out here. If you don't we can and will use force." This, of course, was an absolute lie, but he needed her to come out.
"I'm telling you, I've been here all day," she shouted back from inside her home.
"Then I'm sure you woul-" Shining was cut off when a cloud flew at an incredible speed, through his sister's window followed by Rainbowdash.
"You! Do you know how much trouble you caused me?" Nimbus thought about that statement for a moment, he couldn't have caused to much trouble for anypony today, and if he did, it was all his attempt to stay alive. In his desperation, he shot off a bolt of lightning. It totally missed Rainbowdash and instead hit Spike, who was standing next to Twilight. The force of the bolt and the shock of the situation, caused him spew out emerald at the cloud.
A shout came from outside and small, metal canister flew through the window. "Oh sh..." Twilight managed to say before she fell done from the knock out gas.
Celestia sat by the fireplace in her room. Luna had taken over the duties for today. She let out a sigh, it had been so long since she could just sit down and relax. She felt a tingle in her horn. "Hm, it must be a letter from Twilight." She mused to herself. Suddenly she heard a loud boom and felt a powerful, painful shock go through her body. She needed to have a serious talk with Twilight her recent letters.
