Super Mario Harmony Land

"Fluttershy, what in Equestria happened to you!? Twilight asked. Fluttershy was standing in the library, unable to sit anywhere, since every chair she had tried so far had been crushed under her weight. Spike was busy trying to keep himself from bursting into laughter.

"Well I don't know exactly. There was this box that I found outside my door an-and when I brought it in and set it down on the table..."

"A box did this, Seriously? How can a box do something like this?"

"It wasn't just any old box though. It was big and green really really light, and I mean really light, I hardly had to lift it."

"Fluttershy, your solid metal. You are literally an iron pony. Right know, you are a scientific impossibility. You-  Hold on, what's that sound?" Some disturbance had (thankfully), interrupted Twilight before she could start a rant.

Outside could be heard some particularly joyful sproinging and bouncing, as well as Pinkie Pie squealing with delight. Whatever was going on  outside, Twilight had to find out. Spike was busy trying to keep himself from bursting into laughter.

Outside was Pinkie, coiled in some kind of metal spring, bouncing back and forth across the street like it was some wonderful amusement park ride.

"Hi Twilight!" Pinkie shouted with glee. She landed...  on top of her head. She then climbed out of the giant spring and pulled from seemingly nowhere what appeared to be a rather large oddly shaped grey mushroom. It looked almost spring-like in appearance.

"Hey Twi, look what I found, isn't it neat? You eat it, and then this magic spring appears and everything goes all boingy and wheee! Try it!"

Twilight just blinked. "I...   You... Ate it, and a spring appeared?"

"Yup!" Pinkie said, with a big grin on her face.

"But that's impossible, only magic could do something like that, and I'm fairly certain there are no magical fungi of that nature around Ponyville."

"Silly, how can it be impossible if it just happened? Watch!" Pinkie took a bite out of the shroom, and true to her word, a spring appeared, coiled itself around her, and then bounced higher than the top of Twilight's tree home.

What Twilight felt was not shock, or awe, but more of a feeling that the entire concept of a magical mushroom that turned someone into a spring was ridiculous, and downright improbable.

"*sigh* You know what, I've already seen one impossible thing today, I'm not even going to bother with this one!"

"Huh? Lemme see!" Pinkie poked her head into through the library door. There she saw Fluttershy, except she was solid metal. Even her mane was metal.

"Woah, Your solid metal! How'd you do that!?"

"Um well see, there was this box and..." Fluttershy couldn't finish her sentence, she got distracted when Pinkie poked her in the side with a fork. Pinkie apparently felt the need to test the theory that sharp objects don't work on metal things.

Twilight sighed. A mushroom that practically turns ponies into a spring, and a box that made ponies into living metal. What next, a giant green wind-up boot? No, she would worry, about the shier ridiculousness of this later, first she needed to find out how to fix Fluttershy.

"Spike, see if you can find any books on any spells involving flesh to stone transformation."

Spike hopped up and began shuffling through the various shelves of books. "Hey wait, Fluttershy was turned to metal, not stone."

"I know, but as far as I know there are no recorded spells that can turn ponies to metal, so I'll just have to compensate with something of a similar nature. All I have to do is find out how to reverse the effect.

An hours had past, and she had barely made any progress. She had turned objects to stone, she couldn't turn them back. And there was still the fact that Fluttershy retained the ability to move, which complicated things. Unless a miracle happened, she wasn't going  to solve this problem anytime soon.

There was a knock on the door.
