Rumble and his/her mistake.

Rumble got up in the morning and yawned. He then got up and went to the mirror and combed his long mane to get it to how it us- wait, long mane? He then looked into the mirror again and saw he snout rounded, his mane longer, and he eyelashes longer. "AHHH!" He yelled in a squeaky filly voice.

"Rumble? What's wrong?" He could hear Flitter and Cloudchaser come up the steps and look into his room. They spotted him as he turned to face them and their jaws dropped. After a few moments they thought it was just makeup and Rumble was playing a joke and started laughing, but then they saw him starting to sob, and they realized it wasn't a joke and stopped laughing, getting even more confused.

"H-how did t-this h-h-happen?" Rumble sobbed into his now long mane as Flitter and Cloudchaser went over and comforted the filly/colt.

"I... I don't know Rumble." Flitter shrugged. "Maybe we can get some pony to help you?" She suggested.

"W-who could we c-call? O-only a p-p-princess c-can use g-g-gender sw-sw-swapping s-spells," Rumble said as Cloudchaser tried to comfort him.

"Rumble, If only princess's can use gender swapping spells then how could that one colt turn you into this?" Cloudchaser said she saw that Rumble started to cry even harder. "Rumble, now what?"

Rumble still sobbed as he said only one word. "S-school!"

Flitter and Cloudchaser thought for a moment, but couldn't come up with something. "Rumble, This is a one time thing but only for the predicament you are in, but... I guess you can stay home today." Cloudchaser said but it didn't help Rumble at all. "Rumble don't cry. We can call Twilight to come over and help. She is a princess now, Remember?" Cloudchaser reminded him.

" T-thanks guys," He said as he hugged them, still sobbing. After a couple of minutes Cloudchaser broke from the hug and went to go to the library to go get Twilight. Flitter still comforted Rumble as they waited for Cloudchaser to come back. She then broke the hug and talked to Rumble for a little bit.

"Rumble... don't be so sad. Twilight will fix this!" She then spoke to herself. "I hope..."

"But... But w-what if she c-can't help?" Rumble questioned, still sobbing.

  "... I don't know..." She sighed as Rumble Stopped sobbing after a couple of minutes and Cloudchaser came into the room with a lavender alicorn.

"So this is the filly-" Cloudchaser lightly kicked Twilight "Ahem, So this is the colt who you were talking about?" Cloudchaser nodded. "I have never seen this happen to anypony before. I didn't even know this was scientifically possible!" Twilight exclaimed. "Do you know what caused this?" She asked Rumble as he sniffed and nodded.

"T-this one c-colt cursed m-me." He managed to say which caught Twilight's attention.

"Cursed you? I don't know alot about curses, but I know some pony who knows alot about!" She clapped her hoofs together and grinned, but Rumble didn't "Follow me. You two also." She pointed to the two mares as she began to trot out the door, but Rumble stayed inside. "What are you waiting for?" Twilight wondered.

"W-what if s-s-some pony s-sees m-m-me?" Rumble stuttered as Twilight charged up her horn. 'W-what are y-you do-doing?" Rumble asked as Twilight's horn glowed more.

"Teleporting us there" Twilight said as she shot herself, Rumble, and the twins as they teleported into the middle of the everfree forest with a hut. "Here it is!" Twilight said as she knocked on the door to the hut.
