Babysitting duty

Ponyville

It is a wonderful day today in Ponyville, the ponies and changelings of the town were seen talking to each other, doing work and enjoying their lives as usual.

In King Thorax and Queen Twilight Sparkle's castle, the seven years old Princess Twirax daughter of King Thorax and Queen Twilight Sparkle was seen in her room reading her physics book on her studying desk.

"Wow, the matter's motion and behaviour through time and space is quite intriguing." Twirax commented while reading her book "But, at least I am good at mathematics!" She said with a smile.

Twirax was going to flip over to another page and proceed with her reading, but then, the sound of her bedroom door being knocked on.

*Knock Knock knock*

When Twirax heard the knocking, she must assume that her parents were at the door, it must be the time for them to go to the spa from what she has heard from them last week. So, she got off of her studying chair and walked towards her bedroom door. Once she got to it, she gripped onto the door handle with her magic and pulled it open. Then, she saw her dad and mom.

"Hello dad! Hello mom!" Twirax yelled in an exuberant manner as she hugged her parents, and Thorax and Twilight hugged their daughter back.

"Hello sweetie how are you?" Thorax asked.

"I'm doing great dad." Twirax replied with a smile.

"That's good to hear." Twilight said with a smile towards her daughter "Anyways, as we told you last week, me, your father, uncles and aunts are going to head to Ponyville spa today, and we need you, Viper and Screwball to take good care to Alistair while we are gone okay?" She asked.

"Of course." Twirax replied with a joyful expression "You can count on me, Viper and Screwball." She told her.

"That's my daughter." Twilight said kissing her daughter on the forehead.

Twirax was told to babysit her little brother Alistair for the day while her parents have gone to the spa along with her uncle and aunts. She has agreed in joy of the request because, she loves her little brother so much that she never wants to leave his side. She has also asked her parents if she could invite Viper and Screwball along for the obligation, and her parents replied with a nod of their heads. That got her even more happy.

"I have left you a list of tasks for you and your friends to do with him in the kitchen." Twilight told her "Read through it, and you and your friends will have less complications of the work." She finished.

"Understood mom, you can count on me, Viper and Screwball."

"Wonderful." Thorax said stroking his daughter's head. Then, a brief second later, the front doors of the house was knocked on.

*Knock! Knock! Knock!*

"Oh, that must be the girls." Twirax said.

"Lets head down now." Said Thorax.

Then, Twirax walked out of her room and she and her parents began to walk down the third floor hallway of their home, which was the hallway that belonged specifically to the children, to the stairs of their home.

After walking through hallways and going downstairs in their home for three minutes, Thorax, Twilight and Twirax have all arrived to the front doors of their home. Thorax pulled the doors open, and in front of them were Viper and Screwball.

"Viper! Screwball!"

"Hello Twirax!" Viper said as she and Screwball waved at her.

"Hello you two." Thorax greeted with a smile "Thank you for coming here and agreeing to assist our daughter to babysit our son." He thanked them with a smile.

"You're welcome uncle Thorax." Viper said with a nod.

"Yeah, we're always happy to help." Screwball said with a smile.

"Thank you." Twilight said with a pleased smile "Well, I guess it's time for us to go Thory." She told him.

"Oh yes." Thorax said with a nod "Be safe you two, have a good day." He told them.

"We will."

"Remember Twirax, the list is stuck to the fridge in the kitchen." Twilight reminded her, and her daughter responded back with a nod. "Goodbye you three, and be safe." She said as she gently kissed her daughter on the forehead. After that, Twilight and Thorax walked out of their home and began to make their way to Ponyville spa where they will meet up with their friends.

"Come on in guys!" Twirax told them with an exhilarated expression. Viper and Screwball nodded and entered her home.

Once they were in, Twirax, Viper and Screwball first made their way to the kitchen where Twilight said a note on what to do with Alistair was stuck on. When they got to the cooking area of the kitchen, Twirax pulled of a long piece of paper which had informations on what they need to do with Alistair. After that, they began to make their way to the fourth floor of the castle to Alistair's room.

"So, what are we suppost to do again exactly?" Screwball asked. Then, Twirax began to read the note again.

"Well, my mom said that we first need to play with him, in the afternoon, we must feed him milk, in case if he poops himself, diapers will be in his closet, by the time it gets to half past four, we must put him in bed." Twirax delineated.

"That's it?" Viper asked with a raise of her eyebrow, and Twirax replied with a nod "That sounds really easy!" She said with a confident expression.

"We'll see." Screwball said with a shrug "After all, I wouldn't be too sure about difficult tasks." She told them.

After walking for two minute, the three hybrids have all reached to the door to Alistair's bedroom. Twirax gripped onto the handle with her magic and pulled the door opened, after that, she, Viper and Screwball all entered his room, and they were now standing on his multi-coloured puzzle excise mat. Twirax looked to her far left and noticed her six months old baby brother Alistair sleeping in his crib.

"Awww, he's so cute." Viper cooed softly.

"Agreed." Said Screwball with an adoring expression towards the young hybrid baby.

"Indeed, he is now six months old." Twirax told them. Then, she slowly walked up to her baby brother's bed in order to not inadvertently wake him up. Once she got to his crib, she slowly looked down on her sleeping baby brother and began to wake him up.

"Hey Alistair." Twirax greeted.

When Alistair heard the familiar voice, he let out a cute yawn and slowly opened his eyes. At first, his visions were blurry, but when they worked again, Alistair saw his big sister Twirax, then he cooed happily towards her.

"Hello to you too my sweet little brother." Twirax greeted as she rubbed his left cheek. After that, Twirax reached out for him and gently grabbed her little brother. Then, she gently pulled him up and out of his crib. "Hello there." Twirax said rocking her brother.

Then, she walked up to the puzzle floor mat and gently placed her brother onto it, and Alistair immediately cooed in delight when he felt his hooves on the soft mat.

"Alistair, say hello to your friends." Twirax told him.

Alistair looked up and saw his friend's Viper and Screwball staring down at him with smiles on their muzzles. Then, he cooed happily towards them with a smile on him muzzle.

"Hello Alistair, you're so cute." Viper said gently stroking his head.

"Your cheeks are so squishy." Screwball cooed squishing his cheeks.

"Alright girls, let's get back on task." Twirax told them, then Viper and Screwball removed their hooves from him "Lets get some toys out for him." She said.

Viper and Screwball nodded in unison and stood up from the mat. After that, they turned around and walked to Alistair's toy box. Once they got to it, they pulled open the box and began to search in it. Ten seconds later, Viper brought out a triceratops toy, and Screwball brought out a stuffed teddy bear. The sight hhas made Alistair smile in excitement. Viper and Screwball then turned back around and sat back down on the mat with the toys in front of him.

"Alright Alistair, let's play a game of animal brawl." Viper told him, and that made Alistair bewildered.

When Screwball noticed Alistair's perplexed expression, she decided to delineate on what the game is about.

"Here's how to play the game Alistair." Screwball told him. She then levitated the toys up with her magic "You basically want to hold your toy up like this and make it battle your opponents doll. Your main objective is to make the opponents doll fall on the ground in order to win." She delineated.

Alistair took a moment to understand Screwball's complex statement. After a brief second, Alistair looked back up at her with a smile.

"I guess I'll take that as an 'I understand' then." Screwball said with a giggle.

"Okay, now we've established all of that, let's play!" Viper said in an enthusiastic tone. "Alistair will battle against me first." She announced.

Then, Viper grabbed the plastic triceratop, and Alistair grabbed the stuffed teddy bear with his magic. After that, they began to battle the toys.

"Ha! Don't think that your teddy bear can beat me Alistair, the triceratop will surely be able to-"

Viper wasn't able to finish his sentence when Alistair pushed the toy triceratop out of her claws. After that, the toy fell off of the mat, and Viper had a shocked expression on her.

"Yaaaaaa!" Alistair cooed in happiness with his hooves raised in the air.

"Well done Alistair." Twirax said hugging her baby brother.

"You were saying?" Screwball asked looking at Viper while snickering.

After playing games and toys for two hours, it was now in the afternoon meaning that it was time to feed Alistair some milk. So, they brought him to the kitchen and sat him in his baby high-chair. After that, Twirax went to the fridge and brought him out his baby milk bottle which was already filled with milk. Then, she walked out to her little brother.

"Here you go Alistair." Twirax said softly.

Alistair drooled when he saw the sweet milk in front of him. Twirax slowly held the milk sideways and Alistair bit onto the nipple of the bottle. After that, he began to drink the milk from the bottle delightfully and happily.

"He's so cute." Viper said softly.

But suddenly, Alistair lost his grip on the nipple and accidentally spilled the milk onto himself, some even splashed on Viper's hair and claws which made her gasp in horror and shock.

"Oh no!" Twirax said with a shocked expression.

"Oh my, good thing he's not injured." Screwball said, and Viper nodded in agreement.

"Girls." Twirax called them "Lets go and get him a tissue for him in my room." She told them.

"Okay."

Twirax gave her brother nuzzle first then took off to her bedroom with her friends, leaving Alistair alone in the dinning room.

While alone, Alistair was seen looking around the room to see if there is anything else. And just as he looked to his right, he noticed a three sections cupboard with lots of boxes. But, when he looked up, he saw a jar filled with cookies, and that made him drool because, he wanted to eat the cookies.

He looked at the boxes in the cupboard as well as the shelves for a second and noticed that they were able to be climbed. After calculating the height, lengths and widths of the cupboard with basic maths, a plan was formulated in Alistair's mind. So, he jumped off of his high chair and fell face first onto the floor but, he wasn't injured. After that, he crawled to the cupboard. Once he got to it, he began to commence his plan with a confident expression.

Alistair jumped up and gripped onto the bottom of the second shelf with his hooves. After that, he pulled himself up and gripped onto the box in the second shelf. He repeated the same process again and again until he was on top of the cupboard, although it is a daunting and difficult task for him to do as a baby but, he is quite smart and brave.

Twenty seconds of climbing later, Alistair has made it to the top of the cupboard, and he began to catch his breaths, he has accomplished his mission. After a brief second, he began to walk up to the cookie jar with a pleasant smile on his muzzle.

Just outside of the living room, Twirax, Viper and Screwball were seen walking down the hallway of the first floor and were making their way to the living room with a tissue box.

"After we have cleaned Alistair, we're going to give him a bath okay?" Twirax told them, and her friends replied with a nod.

Once they have made it to the living room door, Twirax pulled the doors open with her magic and entered the living room with her friends.

"Alistair we're ba-"

Twirax immediately stopped in her sentence when she saw that Alistair is no longer in his high-chair anymore. This made her eyes widen in shock.

"What the?! Where did he go?!"

"Oh no, look over there!" Screwball exclaimed pointing up to the right.

Twirax immediately looked to where Screwball is pointing at, and when she did, she saw her baby brother on top of a cupboard while trying to get a cookie jar open.

"Oh no!" Twirax said as she spread her shelled wings and flew up to Alistair.

Once she was at the top of the cupboard, Twirax immediately grabbed her baby brother and pulled him off of the cupboard. After that, she slowly descended to the floor and looked at him.

"Holy sweet Celestia Alistair, you scared me there." Twirax told him, and that made Alistair hung his head down in shame because, all he wanted was a cookie.

Twirax then took a deep breath and exhaled it, calming herself down in the process.

"Its okay Alistair, I'm not angry but, you need to be careful sometimes." Twirax told him, and Alistair nodded to her in acknowledgement "Wonderful, now come on, let's give you a bath." She told him.

After that, Twirax, Viper and Screwball all walked out of the living room and started to go to the bathroom where they will give Alistair a good long bath.

Ponyville spa

In Ponyville spa, the dinosaurs, raptor sister, mane six, Thorax and Spike were all seen taking a nice and relaxing spa. The boys were in one room, while the mares were in another room.

"So Thorax, how's it going with raising your son?" Indominus asked.

"Its alright." Thorax replied with a shrug "He is a very nice and compliant little colt who always listens to me and Twilight all the time." He told him.

"That's good to hear." Indominus commented with a pleasant smile "Then I guess I have nothing to worry about with my daughter taking care of him." He told him.

"Indeed."

In the spa room where the mane six are in, the elements of Harmony were seen bathing together while talking about their lives and all with raising their children and many more.

"Twilight darling, what do you think of Thorax?" Rarity asked.

"What do I think of him?" Twilight asked with a raise of her eyebrow "Isn't it obvious? He is the sweetest changeling I have ever met, he has helped me through lots of distressing situations." She told them.

"I can tell." Rainbow Dash said "How's your son going?" She asked.

"He's going well." Twilight replied with a shrug "One day, me and my husband will have to introduce him to his subjects and what he will do when he is the King." She told her.

"Now that's just wonderful and exciting!" Pinkie commented with a wide smile.

Back in Thorax and Twilight Sparkle's castle, Twirax, Screwball and Viper were all seen giving Alistair a warm bubbly bath while he is playing with some toy ships, Alistair splashed himself in the water while his friends helped rubbing his body with a soap bar and washing it off with water.

"Okay all done." Twirax said. After that, she grabbed her baby brother up and out of the bath. Then, he began to shake the water off of him which made the three hybrids laugh. "Alright now time to-"

Twirax stopped in her sentence when she saw that Alistair's towel wasn't on the metal hanger, she has just noticed that she has forgotten to grab his towel in his room.

"Shoot! I forgot to grab his towel."

"I'll come with you to his room Twirax." Said Viper.

"Okay, Screwball, be sure that Alistair doesn't wanders off okay?"

"You got it."

After that, Twirax and Viper both stood up from the floor and exited the bathroom. Then, they began to make their way to Alistair's bedroom.

"Alrighty then Alistair, now all we need to do is wait while the girls are grabbing your tow-"

Screwball immediately stopped in her sentence when she noticed that Alistair wasn't underneath her anymore.

"What the?! Alistair! Where did you go?!"

Screwball then stood up and charged out of the bathroom. She looked to her right and saw Alistair crawling away while laughing in merriment.

"Alistair come back!" Screwball said as she started to chase him.

Alistair was seen crawling on the floor in happiness after his pleasant bath that he just got. But, his crawling was put to an end when stairs blocked his path.

"Whoa! Whoa! Whoa!" Screwball said as she attempted to slow herself down. But suddenly, she tripped on the carpet floor and flew over Alistair, after that, she tumbled down the stairs roughly. After a five seconds tumble, Screwball has made it to the floor with her chin on it and her body raised upwards. The sight has made Alistair laugh.

Screwball slowly pushed herself back up and stared up at Alistair with an aggravated expression. Then, she walked back up the stairs and once she has done that, she picked up Alistair and began to make her way back to the bathroom.

Twirax and Viper have both just made it back to the bathroom with Alistair's white coloured towel with them. But unexpectedly, Screwball and Alistair weren't in there.

"What the? Where did Screwball go?"

The two eventually got their answers when they heard hoofsteps noises coming towards them. They looked to their left and saw Screwball walking up with Alistair in her hooves. And her hair was ruined. The sight made Twirax and Viper snicker in unison.

"Haha, laugh all you two want." Screwball said in an unamused tone.

After the wonderful bath, it was time for Alistair to sleep. So, they all walked to his bedroom and walked up to his crib. Once they were there, Twirax gently lowered him in it and covered his body with his blanket.

"Sweet dreams Alistair." Said Twirax. Then, Alistair began to snore gently.

"Alright, we have accomplished all of the objectives." Viper said in a proud tone "What do we do now?" She asked.

"I suppose that we could play a board game before our parents return." She said.

Viper and Screwball nodded in agreement and the three hybrids began to make their way to the living room again. But, before they could even make it to Alistair's bedroom door, they suddenly heard a splat noise.

*Splat!*

"Waa! Waa! Waa! Waa!"

Viper, Screwball and Twirax all flinched when they heard the loud crying of Alistair. They all turned around and walked up to his crib, and they immediately noticed a large bump in his diapers.

"Oh no, he pooped himself." Twirax said.

"Does this mean we have to?"

"Yes." Twirax replied with an anxious expression, and that made her friends concerned.

The three hybrids all clipped their noses with clippers and commenced the diaper changing. Viper grabbed a diaper from a box in his closet and handed it to Twirax. After that, Twirax and Screwball both walked up to Alistair's crib. Then, Twirax gave Screwball a nod and she took a deep breath.

Then, Screwball gently and cautiously removed the unhygenic diaper from Alistair and she immediately saw the loathsome and smelly brown poo in it which made her face go green. But, before she could throw up, she placed the dirty diaper in a plastic bag and teleported it to a garbage bin.

After Screwball has done her part, it was time for Twirax to do hers. She wiped Alistair's poo stained area with a clean tissue. After that, she teleported it in a garbage bin. Finally, she wrapped the new diaper around him. Ten seconds later, the diaper changing process was accomplished and Alistair was now at peace. Then, he slowly closed his eyes and slept.

Viper, Screwball and Twirax all unclipped their noses and exhaled in unison as they fell on the floor.

"That was daunting." Viper commented.

"Agreed." Said Screwball.

"I don't think I have the strengths to move anymore." Twirax said in a fatigue tone.

Five seconds later, the three hybrids slowly closed their eyes and fell asleep along with Alistair, except for Screwball who had a little bit of energy left on her.

"I hope that I wouldn't do something like that again." Screwball said. But, when she looked down on her right hoof, she noticed a small poo stain on her, that made her gasp in shock and fear and faint on the floor.

It is now 6:00pm in Equestria, and King Thorax and Queen Twilight Sparkle have both returned to their castle with Indominus, Rainbow Dash, Discord and Fluttershy with them so that they can pick up their daughters.

"Wait right here you guys." Thorax told them. After that, he and his wife entered their home.

Once they were in, the couple started to make their way to the living room where they assume the hybrid trios were. Once they got to it, Thorax pulled the doors open and to their great surprise, Viper, Screwball and Twirax weren't here.

"Huh, now that's weird." Thorax said with a perplexed expression.

"Wait Thorax, I hear something." Twilight told him. The two zipped their muzzles and began to hear the noises, they then realized it is the sound of snoring. And it was coming from the kids floor.

"Lets go."

Then, the couple ran through the hallway and began to follow the source of the noise.

Two minutes later, Thorax and Twilight have both arrived on the fourth floor where the source of the snoring noise is heard. They continued to follow it and noticed that it was coming from Alistair's room. The door was suspiciously opened slight too.

"Lets investigate." Thorax said, and Twilight nodded.

The couple slowly and cautiously began to make their way to the door that leads to Alistair's bedroom. Once they got to it, Twilight gently grabbed onto the handle of her son's bedroom door with her right hoof and pulled it open.

Once they opened it, they both saw Viper, Screwball and Twirax on the floor in front of them while snoring comfortably together. They also saw Alistair sound asleep in his crib as well.

"Aww, what an adorable sight." Twilight said with an adorable expression towards the hybrids.

"Indeed Twinkle's." Thorax said with a smile.
