I'm not a foal

After making sure that Katie was asleep Twilight headed down stares to the front room of the castle. Twilight sat on a sofa reading when she heard a knock at the door. Shifting her eyes to the door she teleported to it and opened it to reveal her friends. "HI TWILIGHT!" An energetic earth pony shouted.

"Pinkie please be more quiet, Katie is trying to sleep." She said in a hushed tone. "But please all of you come in." she gestured for her friends to follow her. As they entered the front room they each sat on different chairs while Twilight put her book back. "So if you don't mind me asking why are you here, not that I don't mind company."

"We thought you might want to hang out with us today." Apple Jack said.

"That sounds wonderful but I have no one to look after Katie."  She said a little sad that she had parental responsibilities and couldn't go with her friends.

"Well she could come with us."  Rarity suggested.

"Ok I don't see why not, but we need to let her rest she had a little accident earlier." Twilight replied.

"Oh dear what happened?" Asked Fluttershy.

The next hours were spent recalling what happened in the library and just normal talking until Twilight thought Katie had enough sleep. "Okay girls I'm going to wake Katie up now I will be back soon."

Meanwhile Katie was in a peaceful slumber dreaming about what her life was like before she came to Ponyville and before all this happened. She was currently having a snowball fight with her friends ,well all except Fluttershy. The fight was split into two teams with Apple Jack, Rarity and Pinkie Pie on one and Twilight, Rainbow and herself on the other. All of them were having fun in the soft, fluffy snow but all of a sudden one of Katie's snow balls hit Apple Jack a little too hard everyone looked at her as if she had committed a murder. Their eyes all gazing on her so she did the only logical thing: she ran.

She ran as fast as her hoofs could carry her but when she saw the six ponies catching up she took off flying as fast as she could. As she looked down she could see five ponies looking up to her. Katie allowed herself to relax only to recount the five ponies to fine one was missing. Her eyes went wide as she remembered she wasn't the only Pegasus in the group. She turned around to fly away but she came face to face with Rainbow Dash. Before she could say anything Rainbow Dash pushed her and flew faster than light straight to the ground.

Just before they could hit the ground Katie's eyes shot open to reveal that she was sleeping and was covered in cold sweat. She looked around desperate to find something to calm her down but realised she was only in an empty crib. Then a familiar voice entered hear ear "I see you had an absolute wonderful dream." Discord said to her.

Katie looked around to find the source of the voice and found the draconequus sitting on a  small plastic chair in the corner of the room. He stood up and walked to the crib "What the hay do you want Discord?" She angrily asked him.

"Now, now that is not the language the should come from a little filly." Discord stated.

"Well as you failed to tell me I don't think Twilight can understand a word I say." Katie exclaimed.

"What did you expect you are a foal after all."

"That is only because you made me one!" Katie was almost on the verge of shouting at him.

"Ok fine you win, but the spell is irreversible you will have to wait the six and a half days. Good luck." And with that he vanished into the air.

Moments later Twilight Sparkle came through the door. "Hello Katie did you have a nice rest?" Knowing Twilight wouldn't understand her she simply nodded. "So do you want to come out with me and my friends?" Thinking back to the dream she had minuets ago Katie quickly shook her head. "What is wrong do they scare you, you don't need to worry mommy is here."

Twilight put on a foal carrier and used her magic to gently place Katie in it. As soon as she knew Katie was secure she walked of to meet her friends in the front room. From her position Katie could see her legs hanging out of the foal carrier and the endless rows of paintings on the wall. The paintings didn't really interest her they were mostly old people she didn't know. But one caught her eye, it was a picture of Twilight standing next to somepony each with a caring smile. The pony next to Twilight was a Pegasus with a light orange coat and a dark blue mane.

Katie grabbed Twilight's attention and pointed to the picture. "Oh that" Twilight responded seeing the picture. "That is just me and your father ,Flash sentry he is not around much because he is in Canterlot guarding the princesses."

When Twilight arrived to her friends they all stood up and got ready to leave. "Where are we going first girls?" Twilight asked.

"Let's go to Sugarcube Corner I haven't had a cupcake in days. What do you think Fluttershy?" Rainbow dash said.

"Well um I don't mind." Fluttershy replied nervously.

"Okay it is settled we are going to Sugarcube Corner." Twilight announced.

The six ponies left the castle in a slow walk heading to the centre of Ponyville. Katie waved to passers by and listened to the other pony's conversation with interest. She could only hear parts of the conversation but she still tried to hear it. The grown up ponies were talking about Apple Jack's next harvest and possibly helping her with it.

After an hour of staring at the floor and hearing only half a conversation Katie could see a sign on the side of a building that was a giant muffin. Katie had only been to Sugarcube Corner once or twice because she didn't like the muffins they sold there. As they all got in a booth Twilight sat Katie on the table and they all decide on what to order. Finally after what seemed like hours of deciding they chose a chocolate muffin for Rainbow Dash, apple cider for Apple Jack, a big berry pie for Pinkie, 2 glasses of water for Rarity and Fluttershy, banana flavoured foal food for Katie and nothing for Twilight.

"TWENTY BITS!!" Rarity screamed.

"It's ok I can pay." Twilight said.

"But you aren't even buying anything Twilight." Apple Jack argued.

"It is really ok my castle came with a lot of money so there is no need to worry."  Twilight said with a smile

"Well I'm going to the bathroom I'll be back later." Pinkie Pie said to the group.

"Okay hurry back." Rainbow added.

While Pinkie was gone the group talked and ate but they failed to notice a certain pink earth pony creeping up to the booth where her friends were relaxing. Pinkie got closer and closer mere inches away from the light grey Pegasus foal enjoying her food. Then all of a sudden she grabbed Katie and screamed, "GOT YOU."

The result scared the ponies by the table and alerted half the store as well. But the biggest reaction was the foal she grabbed Katie jumped so high that if her wings were normal there would probably have been a hole in the ceiling. When she landed on her spot on the table Twilight scolded Pinkie "Pinkamena Diane Pie if you ever scare my daughter like that again I will personally throw all your cupcakes into the nearest volcano. Am I clear!?" Pinkie just whimpered in response. "AM. I. CLEAR." Twilight shouted.

"Yes" Pinkie said in the quietest voice anyone had ever heard come out of her mouth.

"Ok thank you." Twilight said returning to normal with a smile. This shocked everyone on the table even herself she had never shouted at her friends like that she decided it must have been her motherly instincts. All the ponies calmed down except Katie who was still in deep thought with her mouth agape until Fluttershy noticed something.

"What is that smell?" She whispered to Rainbow Dash.

Rainbow now fully aware of the smell spoke up. "Twilight could you um change Katie please she is making a really bad smell." hearing made Katie's face glow red with embarrassment. She really wanted to be changed due to her diaper now being incredibly uncomfortable and the smell was enough to make her want to vomit.

Twilight looked at Katie who was sitting down with a hoof over her nose signalling that she didn't like the smell either. "Um sorry everypony but I left Katie's diapers at home." Twilight said. Now the smell from Katie was starting to attract the attention of everyone else in the store and this was beginning to get even more embarrassed and looked to Twilight pleadingly. "Ok we will be back later bye."

The walk back was the most uncomfortable thing Katie had ever endured, the poop now spreading about further increased the smell. Thankfully she saw the beacon of hope that was Twilight's castle. When they entered Spike was cleaning in an apron. "Does he normally wear that?" Katie thought.

"Hello Twilight," the dragon welcomed "why are you back so soon?" He asked but a very strong smell gave him the answer. He covered his nose and ran away before the alicorn could say a word.

"Ok Katie let's get you changed, and maybe a bath." Twilight continued up to the nursery desperate to relive the filly of the diaper. She came to the nursery and used her magic to open the door. The door was surrounded by a purple glow as it slowly opened Twilight approached the changing table and placed Katie on it. Katie shifted awkwardly as  Twilight  undid the diaper and gasped when she saw the mess that almost made her gag. "Wow Katie," Twilight giggled "What caused this?"

Katie's face turned crimson as she tried to hide her face in her hoofs. "It is your fault for putting that foal carrier so tight." Katie said. Twilight started to wipe her but stopped when Katie started to wiggle away from the wash cloth.

"Do you want to be cleaned or what?" Twilight asked Katie replied by staying still and allowed her mother to continue. After the whole process was complete Katie was put on Twilights back and Katie shot her a questioning glance. "What?" she asked "do you not want a bath?" With that Twilight started to walk down to the bathroom with a very embarrassed filly on her back.
