My Little Mecha

   It was a nice sunny day in Ponyville, everypony had something to do, Rainbow Dash was flying, Pinkie was baking a load of cakes, Rarity had a commission for a set of dresses, and Twilight was reading some books in her castle. All was peaceful, but something was hidden underneath the town.

  "Spike, how great is it to have some peace and quiet for a while?" Said Twilight, reading a book on biology.

  "Yup, no creepy undead tyrants, no identity stealing bugs, just my comfortable little bed and my friends." The little dragon replied, almost falling asleep.

  After a while, Pinkie stepped in to give Twilight and Spike some of her brand new cupcakes, but a small earthquake occured and the treat fell on Twilie's book.

   "I'm sorry Twilight, I totally didn't mean to ruin your book, I just wanted you to taste my new cupcake, I'm so sorry!"

   "It's okay Pinkie, I'll get another one to read, but I'd also wanna know what caused that..."

   Meanwhile in Canterlot, the princesses were having tea until another earthquake hit, making the tea cups fall on the floor and break.

   "Ugh, I'll get the broom and some more tea..." Said Luna, annoyed

   "Umm..." Celestia grabbed a paper and a quill to write for Twilight "Dear Twilight, you must have noticed these strange earthquakes, quite hard not to, well, I wanna ask you to find what is causing them. Princess Celestia P.S. I'd love if you came over for tea some other day, I really haven't seen you so much."

   Celestia placed a mail stamp and magically sent it to Twilight, the purple princess got the message and started a group to find out what's making the earthquakes, little did the poor ponies know, their culprit was not some mole or other average critter, underground, a huge magical serpent was looking for a set of ancient weapons buried somewhere in Equestria

   "Alright, Team A, search around the north up to the mountains, B and C, you're both going around the river to the east to cover more area, D, you guys check for geological anomalies towards the south, finally, E, you guys check the West. Pinkie, Rainbow, the others and I will check around Ponyville. Leaders, blow on the horn if you find something of interest." Twilight yelled out, ordering the teams where to look for whatever is causing the earthquakes. But the searches had to be cut short because of the storm the pegasi planned for that day.

   Through the night, the earthquakes got stronger, until by morning, all building were wrecked and small hills appeared on the ground. After some silence, the beast showed itself, the Leviathan, it shot fire all over the town and ram into Twilight's castle,which sent her tumbling to the basement. Down there, she found a strange door she didn't notice before.

   "Spike, come down and see this!"

   The sleeping dragon hardly wanted to wake up, but he wouldn't leave his best friend hanging like that, so he managed to get up and walk to the basement.

   "Why did I have to wake up now, Twi..." Spike said, trying his hardest to not fall asleep mid-sentence.

   "I bumped into a wall when that thing rammed the castle, and it opened a secret room! I wonder what's in here."

   Twilight stepped in and found a light switch, what she found in front of her was amazing for the two of them. A set of humongous machines, rusting and sitting there. They seemed to have been there for year and years.

   Curious, the purple princess stepped into one of them and sat down, in front of her were 2 consoles on the floor and ceiling, both full of levers, buttons and screens.

   "Which button should I try first... I think I'll press this "Start" button"

   As soon as she pressed the button, the door behind her closed with her and Spike inside, the buttons and screens lit up and a pair of control levers popped out on the sides, the giant weapon came up from the ground, surprising everypony along with the Leviathan.

   "Okay, I'm in a huge machine I've never used before staring at a monster that destroyed most of Ponyville overnight, no big deal" Twilight said, trying to stay calm and positive while doing so.

   "Spike, what would you do if you were in my place."

   "Well, I'd probably press a bunch of buttons, trying to find out what they do, and I'd probably start with that bright red one on the side."

   Twilight pressed the button hoping for something to happen, it set up and fired two missiles, which completely missed the Leviathan, instead hitting a far away mountain and bringing it to the ground.

  "Eh, I never liked that mountain anyway, good riddance." Spike commented on the failure. "Maybe you should find out how to move this thing, so that serpent guy doesn't kill us!" He continued, panicking at the Leviathan dashing towards them.

  "What's is the most logical way to move something like this... The pedals, of course!" Twilight thought and realized, so she turned and dashed to the side, making the Leviathan fall on the castle, breaking off a large branch. It was her chance to properly fight, she picked up the snakes tail and threw it off into the nearby lake.

Once again, i'm too lazy to finish it now, wait for another time.
