These comical events occurred after chapter 43 of the story "The Chronicles of Summer Rain" found elsewhere. Indeed this account will make a lot more sense after reading Fluttershy's sister's chronicles. At any rate, everypony and their Equestria Girls 'Twins' are enjoying Equestria together during these events.
After the amazing ending to 'Twins Day', Equestria Girls sisters Fluttershy and Summer Rain understandably wanted to spend the next morning together. These sisters had come catching up to do.
Equestria Girls Fluttershy constantly mourned the death of her sister in their world, and only after coming to Equestria the second time, was Fluttershy amazingly and joyfully re-united with her 'dead' sister, who was in Equestria all this time. They were both happy beyond belief to be together.
Their 'Twins', Equestria ponies Fluttershy and Summer Rain easily understood, and headed off together to visit Princess Twilight, who was still, no doubt, enjoying every minute with her 'Twin', Equestria Girls Twilight Sparkle.
Summer and her sister walked into the Library, and both bowed to Princess Twilight. Then, Summer jumped up quickly, and hugged her Princess tightly.
Princess Twilight was in the middle of teaching Twilight Sparkle some advanced Levitation skills. As has been noted, Equestria Girls Twilight was also a Unicorn in Equestria, and was herself learning magic quickly.
Almost without thinking, Princess Twilight asked "Summer, do you want to join us?" Maybe Princess should have thought this through first.
For a little more background, Summer never learned what her Cutie Mark stood for or what her 'special ability' might be. Only two days ago, did Equestria pony Summer Rain learn that she was a rare Phantom Alicorn, and possessed great magical ability. But she wasn't a Unicorn, and so had no knowledge of magic.
In other words, Princess Twilight really couldn't be faulted for the suggestion.
Twilight Sparkle had progressed in her magic to the point that she could briefly lift an approximately watermelon sized rock for a short time. The rock was still sitting on a small stool in the Library.
Princess Twilight calmly asked Summer if she wanted to try.
Summer rewarded her with a blank look, she didn't even know where to start.
Well Princess Twilight wasn't sure either. She thought a minute then said "Summer when you used your magic the other day, your Cutie Mark seemed to be the key for preparing you for the use of your magic. Can you control that process?
Summer thought a minute, and then said "I don't know, let me try."
Summer then threw herself back on her hind legs, and quickly transformed into her Equestria Girls form and stood up. As has already been noted, Equestria pony Summer Rain seemed to be the only one able to effortlessly transition between these two forms.
It also needs to be noted that Summer's Cutie Mark was covered by her clothing at this point, but the glow of her mark did show some through the material.
Just like the other day, Summer's wings appeared on her back, followed by the appearance of her pure White Unicorn horn on her head. They also heard the very low rumbling that accompanied the presence of her horn.
In the confines of the Library this sound was almost loud, and at this point Spike, Fluttershy and Twilight Sparkle backed slowly and cautiously towards the door.
Princess Twilight was to Summer's side, and she did back a little further around, away from the rock.
Princess Twilight said softly "Nice Summer, now try to move the rock.
Summer didn't know what to do, and sat there a minute motionless. She couldn't figure anything out.
All of a sudden, her nose itched, and Summer sneezed.
The rock moved... ...fifty feet out into the meadow behind the Library... Oh, and a huge piece of the wall of the Library moved first, and landed fifty feet further. Princess Twilight could see far off into the distance across the meadow from her new 'window'...
Equestria Girls Summer was quickly back into pony form, unwound her Cutie Mark, and fell at Princess Twilight's feet crying.
Princess Twilight was very encouraging and carefully brought Summer back up, then hugged her. "It's ok Summer" Princess Twilight said softly. "Equestria can afford things like this to better train the only Phantom Alicorn to grace our land in 1000 years."
Then she smiled at Summer.
"However" Princess Twilight continued, "we probably should find a safer place to do this."
Princess Twilight next addressed her 'Twin', Equestria Girls Twilight Sparkle. "Twilight, Summer and I can do this later if you like, I don't want to do things you have no interest in."
Twilight Sparkle was impressed. "I am amazed at such magic. This is fine Princess. Let's do what we can."
Spike quickly volunteered to stay in the Library and 'clean up'.
Princess Twilight and her Twin, along with Equestria ponies Fluttershy and her Sister Summer, headed out the door, and were soon out in the meadow outside Ponyville.
On the way, Princess Twilight used her magic to pick up a rock that was half the size of the one Summer had 'moved', and simply carried it behind her with her magic.
Princess Twilight was looking for a suitable place in the meadow to put the rock, that would allow Summer to 'move' it, facing away from Ponyville, preferably.
At this point, they heard some voices, and the Rarity Twins walked up with Dawn Flower. They were wandering in the meadow, just enjoying the morning, and picking flowers.
Everypony hugged everypony, and then Equestria pony Rarity noticed the large rock floating behind her Princess.
Rarity had some past experience with dragging a huge rock around, and was hoping this wasn't a repeat of that awful day.
"Princess Twilight" Rarity said slowly, "is that a rock you are carrying behind you?"
Princess Twilight had forgotten about it already. She sighed, then said "Yes... I'm trying to help Summer with her magic, and we are trying to find a saf--" Princess Twilight decided against finishing.
They soon wandered off, and Summer spoke up and said "Enjoy your morning girls"
Still, Rarity did stop and look back at Princess Twilight and her rock again before they wandered off across the meadow.
"We can't do this here..." Princess Twilight said slowly.
Princess Twilight decided they would head to Sweet Apple Acres. Surely Applejack would have a remote spot for such experiments.
It would be a 10 minute walk to Sweet Apple Acres, and the Twilight Twins led the way talking together as Fluttershy and her sister Summer walked together behind them.
After a few minutes, Summer said quietly "Sis stop a minute."
Summer transformed into her Equestria Girls form, and then reached out and grabbed the bottom of her sister's front leg nearest Summer.
Fluttershy immediately changed into her Equestria Girls form, and Summer just wrapped her hand in her sister's hand, and Summer helped Fluttershy unsteadily to her feet until she was standing up like a 'people'. Then they hugged tightly together. "I love you Sis" Summer said, and Fluttershy said the same thing back.
They were soon walking together, arm in arm as sister's do, enjoying every minute together. They quickly and silently caught up with the Twilight Twins.
After a few minutes, Equestria Girls Twilight turned around for some reason and gasped.
Princess Twilight stopped and turned around as well. She said lovingly "Summer..."
Summer said softly to her precious Princess, "I am sure we can find another rock on the Farm Princess..."
The rock quickly hit the ground.
Summer then took her free hand, and transformed Equestria Girls Twilight Sparkle, who immediately stood up as she normally did.
Twilight then did the same thing with Princess Twilight, and before long they were all walking arm in arm, to Sweet Apple Acres.
Everypony saw them walking up to the barn this way.
The Applejack Twins joined them immediately, and the six of them hugged tightly.
Summer next said "Applejack, Princess, catch your Twins.
They were all quickly back into Pony form.
They chatted a few minutes, then Princess Twilight got to the task at hand. Princess Twilight spoke slowly, and was trying to phrase the question carefully.
"Applejack, do you have an... ...area fairly close that we can... ...work on Summer's magic... ...uhm... ...without having to worry about... ...hurting your trees?"
Without asking any other questions, Equestria pony Applejack led Princess over to a fence at the edge of the pasture to the south.
"I don't know if you can see it from here, but there is a 10 acre, fenced-in patch of dead apple trees to the south" Applejack carefully pointed in the right direction.
"You can do anything you want in there. Big Mac and I haven't figured out how to clear the old trees away yet, or we would have planted new trees by now."
Apple Bloom asked if she could come watch.
Princess Twilight hesitated, then said simply "Maybe next time."
The Twilight Twins and Summer and her sister Fluttershy were soon standing in the corner of an orchard full of blackened, dead trees.
Princess Twilight walked a few steps towards the closest one, and asked Summer to join her. "Ok Summer, start your Cutie Mark."
As she did, Fluttershy and Twilight Sparkle backed up towards the fence corner behind Summer.
Summer was soon standing in her Equestria Girls form, with both her wings and her Unicorn horn. Everypony could still hear and feel the low rumble that accompanied this Phantom Alicorn's horn.
Princess Twilight calmly said "Ok Summer, I want you to just move that closest tree, just a little. I am not sure how to suggest that you try, but we are not in a hurry, take your time and see what you can do."
For a minute, Summer did nothing. Then she got an idea. She held her right hand up, and made a motion to simply grab the tree with her hand.
The tree moved.
"Very good Summer, now see if you can move it a little more" Princess Twilight said encouragingly.
Summer was now visibly moving the dead tree, it was easy to see that the branches were moving quite a bit.
Princess Twilight began to encourage Summer again "Wow Summer you are doing ver--"
A large 'Pony Fly' immediately landed on Summer's forehead. Without thinking, she brought her right arm up to chase it off.
The tree jumped out of the ground, roots and all, and flew over a hundred feet into the air, launched on a slow curve backwards over Summer's head. Dirt showered over everypony.
Fluttershy shrieked, and Twilight Sparkle gasped in amazement.
Maybe there just wasn't a completely safe place around a Phantom Alicorn.
Summer was quickly in the air, and tracked the tree, making sure it was not going to do any harm.
The flying tree landed, upright, in the pasture fairly near, but behind the Barn. It's roots quickly dug into the soil from the fall.
Summer was quickly flying back to the rest.
Summer changed back to her Pony form in mid-air, and her horn was gone. She landed carefully near the group. She hugged everypony, and apologized. Her sister was shaking with fear, and Summer just held her a few minutes until she calmed down.
Next, Summer changed back to her Equestria Girls form, and asked everypony to stand back. They quickly did.
Summer spun up her Cutie Mark, and went to work.
She walked around the orchard and pulled the dead trees out of the ground, one at a time, and threw them into a large pile in the center of the orchard.
The pile was getting too high, so she flattened her right hand and made a downward motion which crushed the trees close to the ground, accompanied by the loud sound of cracking, splitting wood.
Before long, the fenced-in field was clear of trees except for the pile of dead wood in the center.
With her left hand, Summer doused the ground around the pile with amazing amounts of water as she walked in a large circle around the wood.
Then she walked back to the others, and used her left hand again to throw a fire-ball on the pile of dead wood, which immediately burst into flames, and a huge bonfire resulted.
Everypony was far away, but they could still feel the heat.
Both Applejacks ran quickly up at this point, fearing a fire in their orchard.
They gasped at the clear orchard with a pile of wood burning in the center of it, but asked no questions.
Summer walked up to her sister Fluttershy, and put her arm around her pony neck, and she was quickly changed into her Equestria Girls form, and just hugged Summer close.
Before long, the Twilight and Applejack Twins joined them, and still hugging, they watched the fire for a while together, leaning against the fence.
The Rainbow Twins saw the smoke, came to investigate, and quickly joined them as well.
The trees had been dead for a while, so burned quickly, and soon just a mound of embers were left.
It was lunch time anyway, so they headed back to the farm, intending to head to Town after that.
When they reached the gate next to the Barn, they saw Big Mac standing and looking at the dead tree that had recently sprung up next to the barn. He knew there wasn't a tree there this morning. He knew dead trees can't grow, especially not that fast. He was dumb-founded.
Summer shooed everypony past the barn, spun up her Cutie Mark, yanked the tree out of the ground, then chucked it carefully into the center of the pile of embers in the cleared field to the south, and it was soon blazing brightly, then just as soon went out.
Nopony said a word... ...except Apple Bloom
She ran up to Summer before anypony could stop her, hugged Summer tight, and said "That was amazing!"
When she touched Summer Rain, she was amazingly transformed into the "Equestria Girls" form, and Summer quickly grabbed her so she didn't fall over backwards. Then she stood up like a 'person' completely amazed.
The Applejack Twins came over, joined in, and themselves assumed their Equestria Girls form, and Equestria Girls Applejack quickly picked Apple Bloom up, as she had done with her own sister many times. She was quickly crying.
Everypony was soon back to 'normal', and all the Twins, along with Summer and Fluttershy wandered back to Ponyville.
Princess Twilight told Summer she had made remarkable progress.
Shysage had watched all this begin to unfold on his 'scope' thing that he kept in his house in Cloudsdale. After the rock went through the wall at the Library, he was laughing hysterically.
Right this point, Princess Celestia walked in to talk to this Canterlot Recorder about his new house in Ponyville.
Shysage got very official as quickly as he could, and showed Princess Celestia the big hole in the Library wall, and explained how it got there, and what was going on, trying not to laugh any more.
They quietly watched the rest of these events together.
When the tree flew through the air, Princess Celestia laughed loudly too, but only for a short time.
When Princess Twilight said "remarkable progress" Princess Celestia said "Indeed" herself, then thanked Shysage for letting her watch.
Princess Celestia was leaving, and halfway out the door, she stopped and said to Shysage "Next time you see Summer, please ask her to keep her magic under wraps from now on. Oh, and I want to see that story." She was smiling.
"Of course" Shysage said bowing his head low.
