Pinkie was in hysterics when she woke up.
The world was completely messed up, she could admit to herself -- to anyone, including the walls and floors. They all looked green and purple, like Spike, Only they had big bouncy eyes and a happy cartoonish mouth....And the fact that they were all talking and singing about the happiness of life.
She shook her head, realizing her mane was flattened somehow. Ah she realized -- Rarity had put her into a crazy state of which she could not easily escape, though could, being a vampony and such. Grimacing at her new hairdo, she poofed it up with a small hint of a smile, and went back to scowling again.
The window helped shine glowing moonlight throughout the room. It was not dark, yet not light either -- that was the essence of the moon. It was not bright, nor complete darkness, for it could, as well as the sun, create light, though not effect photosynthesis for the plants. Pinkie noted that pointless bit of knowledge she gained and wondered to herself how could the plants and farmer ponies survive during Nightmare Moon's era (if she were to defeat them all with Rarity, which was very unlikely). For the moon did not help with their growth and survival. She had learned about that also during another one of Twilight Sparkle's lectures about photosynthesis.
Examining her surroundings, she noted that she was in some sort of Canterlot dungeon, in one of the prison cells. The poles were rusty and the walls and floors also, as they were made of the same material -- metal.
That was one of the worst mistakes to put a vampony into.
She got up slowly, with total confidence, and put her hooves on the bars. With all her strength, she tried pulling on them -- to break out -- but it had ended in the part where the bars had electrocuted her and sent her flying back. Useless.
Rarity and Nightmare Moon must have been thinking outside the box, creatively. They had planned and known that Pinkie would have thought of doing so and added the extra protection on the special bars, enchanting them so they would zap her, or anypony, who touches it.
Looking at it once again, she noted that there were no keyholes on the outside or inside, and no key as far as she could see, so Pinkie wondered how they got her in, or how she could get out. Transportation? Yes, that would have been useful -- except she was an Earth Pony. She trashed the thought.
Suddenly, she heard soft hoofsteps -- they seemed to be coming closer and closer. She suspected that it was Rarity, since Nightmare Moon had more of an elegant walk and would much more be preparing the prisoners for something, she did not know, and would have sent her 'wing' pony (though Rarity was a unicorn, except for that one time where she had enchanted fake wings, ha!), which was Rarity, to check her most prized prisoner. But, as the pony came closer, she recognized her and saw that it was hugely unlikely for it to be Rarity.
"Blinkie! What the hay are you doing here?" Pinkie shouted, "I thought you were supposed to be on the train!"
Blinkie sighed, pulling her hair behind her ear so it showed both her eyes. She had a bag on her back, which was lumpy (she did not want to know what was in it) and moving. She rubbed her hoof on the ground.
"You told me that I could come whenever I wanted," she reminded her, straightening up a bit, "And I had felt, I do not know if this is an emotional connection or something, but I felt that you and the others were in trouble. I had remembered Rarity from somewhere and suddenly realized that she was buisness partners with mother -- I recognized her voice since I was always up in my room whenever she came and discussed things with her. I had just decided to check on you to see if you were okay."
Pinkie nodded, understanding her younger sister's worry. "Yep. You predicted correctly -- I'm stuck in this horrid prison and Nightmare Moon and Rarity are completing their evil scheme and doing something -- I don't know what but I know it's something horrible -- to my friends. You've got to help me!" she nodded, then cocked her head, "What's in the bag, first of all?"
Blinkie nodded. "Yes, that," she turned and opened the bag, two small filly heads poking out, "You forgot them in the train car. They were eating the food all the way here, I'm afraid they were very hungry and ate most of my supply," she laughed, "Anyway, I thought they may be useful to you since, you know..." she looked at the ground as if she had disappointed her older sister.
"Oh, you hungry little munchkins!" Pinkie teased, glancing at the Cake Twins, then looked back at Blinkie, confused, "What are you doing? You look...like you disappointed somepony."
Blinkie perked her ears up and stood taller immediately, "I'm sorry, sister, it's just I'm very used to doing that whenever I do something to Inkie or Mother. They are almost always disappointed by me."
Pinkie laughed. "Don't worry, and why would I be disappointed? I'm pretty much the opposite. You have come to rescue me and now you deserve thanks. Now, er, do you have some kind of plan to get me out of this cage? I'm pretty much stuck here -- the bars electrocute you when you touch it."
Blinkie cocked her head. "Hmmm...now do they? Mother had told me about something like this once..." she trailed off, trying to remember, "Oh yes! When a vampony unicorn chants a spell about electricity, a powerful enchantment, this would only apply to their own species. It cannot be harmful to griffons, dragons, you know, as well as ponies or lycans. It's only fair."
"So vamponies do have a source of weakness?" Pinkie questioned.
Blinkie giggled. "Of course, all vamponies have a limitation of power," she explained, "But another way of reflecting it, I just thought of it. Why not let the Cake Twins try? Their fangs have not properly grown in yet and therefore they are not yet vamponies, not full-grown at least. They just have the powers of them, so they could still bend the bars at will."
"I guess we found our loophole, then!" she winked.
"Yep," Blinkie answered.
The blue mare crouched down on her fours behind the two babies. "Now, Pumpkin, Pound, if you want Pinkie to stay alive and end eternal night, then break those bars for us, sound good?"
The Cake Twins paused for a moment, then nodded, giggling as if this was some sort of game for them. They threw their arms at the bars and within the gasps of both of the mares, touched them without any effect from the electricity. Pinkie exhaled with relief as they used their vampony strength to break open the bars, and after a few tries, successfully did so. The bars held no chance against them and quickly crumbled into dust on the fourth hit.
Pinkie's eyes widened, and took no hesitation to escaping the prison, picking up and hugging the twins gratefully while doing so. They looked innocently up at her, laughing.
And she could say this was one of the best moments of her life.
