I am Captain Jack Sparrow, savvy?

As Celestia watches Jack leave to get Gibbs, she thinks about her assistant in Canterlot. She levitates a piece of parchment towards her, then a quill and inkwell and starts writing, 'My diligent and dutiful assistant, I have succeeded in birthing the foal. It is a filly and surprisingly an alicorn, we both chose a name and her name is Summer Poppet. Sadly, she cannot remain as one, or she will not get an everyday life, therefore something will have to be done about them. I have decided to make today a holiday called the Summer Sun Celebration, where I allow the sun to stay up longer than any other day in the year. This way, Equestria's citizens will unknowingly celebrate Summer's birthday and the anniversary of Jack and I's wedding set for the same day next year, June 21. Let's get started on making today an official holiday, so send me whatever necessary documents I shall need to sign. Also, make sure to find the best crafts pony to make a jewelry box with a hidden compartment inside to allow me to hide Summer Poppet's birth certificate in it. Need I remind you not to mention the filly to them? This is supposed to be a secret, the more ponies that know about it mean more ponies for me to threaten with severe punishment if it gets out. P.S. Burn this after you read it.' and teleports it off to her, feeling drained from using magic to write that letter and send it off. She then hears some grunting outside as the door opens to reveal Jack walking backward slowly into the room carrying a beautiful walnut bassinet with golden designs around the flat sides at the bottom with round spindles at the sides to keep the filly from falling out of it.

Covering her mouth from how beautiful it is, her eyes water as tears trail down her cheeks saying, "Oh Jack...it is so beautiful! I know you made sure to get what I told you we needed, but you kept me from ever seeing any of it."

Jack continues walking backward when he backs into his table saying, "Ow, you've run me into the table Gibbs." Then shuffles to the side so they can set it down in front of it.

Gibbs shuffles to the side while keeping a firm grip on the heavy bassinet saying, "Apologies, Cap'n. This thing weighs more than a cannon!"

The captain chuckles and grins saying, "Aye mate, but it was necessary to have for the filly, and it was worth every bit of gold I gave for it and the crib. The crib matches this bassinet, love. Is there anything that we might have forgotten, love?"

Celestia thinks it over a moment before saying, "Ah yes, the most important things of all. We will need enough diapers to get through the first four months, after that we will have to get bigger diapers but we can wait to get those. We will also need wipes to clean her whenever we change the diaper and baby powder. We will need to get that at Manetown in about three weeks, however, I think it would be best if I go with you because it would be a good experience for us and you to learn how to care for a baby." She then looks down at her little filly and sighs happily when she looks at the wings on her back and says, "I think that it would be for the best if I used a spell to seal her wings within her body so when other ponies see her, they will think she is a unicorn instead of royalty. What do you think dear?"

Jack looks at his daughter and nods his head saying, "Won't that affect her at all, love?"

The princess then chuckles and says, "No it won't bother her because she won't know she has wings until I release the seal on her body, what the spell does is it turns her wings into magical particles that she won't be able to use, know of, or feel."

The captain trails his fingers along his beard and thinks about it for a moment before saying, "I agree to your suggestion, then she will be able to experience a somewhat normal life, what with having a pirate father and a princess for a mother and all."

She then smiles and looks at Jack saying, "She will have one interesting life, I'm sure of it. Oh could you have the cook make me some food, I'm starving after all that effort."

Four hours pass by when Smooth Flight wakes up and hears a neighing cry coming from above, bringing a wide smile to her face as she excitedly gets out of the hammock she is laying on. As her hooves land on the wood under her, she quickly rushes up the stairs to go see the foal.

As she reaches the top deck under a night sky, she looks around the deck, lit up by a few lanterns hanging from the main mast and a couple of rails as she sees a cabin at the back of the ship. Knowing that it is the Captain's cabin, she walks towards it and knocks on the door saying, "Excuse the interruption Captain, but I wish to see the foal. May I have permission to enter?"

Jack rises up from laying his head on the table and looks at the door before looking at Celestia and asking, "Is it okay to let her in, love?"

Celestia looks at him while holding her filly in her arms saying, "Of course it is dear, go ahead and let her in to see our foal."

He then looks at the door while striking a match and lighting a couple of lanterns above his table saying, "Come on in, she says it's alright."

Smooth Flight opens the door and enters the cabin, closing the door behind her as she looks around the dimly lit room saying, "How can you see in here, it's so dark."

The princess then chuckles and says, "Well, my little pony, it takes a little longer for a pony's eyes to adjust than it does a human's. So just stand there for a couple of minutes and you should have an easier time to find your way about the cabin."

She then looks towards the right corner and sees a light grey figure in the corner saying, "Yes, Your Majesty. I'm sorry for being so eager to see your little filly."

Celestia chuckles again and says, "It is alright, I'm not upset. It's only natural for a mare to want to see another mare's foal, it makes us want to have our own foals."

Jack then looks at his love and says, "It's madness."

The princess then grins and says, "It's how a kingdom grows."

Smooth Flight stands there for a little while until her eyes adjust to the dim light and sees Princess Celestia leaning gently against the headboard with a little unicorn foal cradled in her arms, having a black and white painted coat with a blonde mane and tail. Her eyes grow large as she gasps and puts her hands over her mouth as her eyes sparkle with wonder, then looks up at Celestia and asks, "M-May I hold her, Y-Your Highness?"

Celestia smiles and nods her head saying, "Of course you can Smooth Flight, come over here and meet Summer Poppet."

The captain watches as Celestia instructs her on how to hold her correctly, then gently passes the filly to her thinking, 'Oi, I haven't held the baby yet...'

The pegasus captain's sparkle as she looks at the little filly in her arms and coos, "Oh she is just so adorable, princess! Now I must have one of my own."

The princess lets her hold Summer for a couple of minutes before raising her arms to take her back asking gently, "Alright now, can I get her back please?"

Smooth Flight carefully hands her back to her, delighted in how adorable she is and says, "I can't wait for the season to come around next week." She then looks at the filly's back and says curiously, "I am surprised that she isn't an alicorn like you, Your Highness."

Celestia chuckles nervously and sighs saying, "Well...you see...she......is, I just used a spell to keep them hidden for a time until the public won't give her the royal treatment and spoil her life. I want her to grow up and experience a normal pony life, not restricted like I am. So you cannot, under any circumstance, tell any other pony about this filly being an alicorn or my daughter. I take it my assistant filled you in on everything you needed to know about my plans involving this filly?"

Smooth flight nods her head and says, "Yes, Your Highness, she did. You plan to take about eight years off and then make your grand return to Canterlot, claiming to have found a filly that has been neglected by him and take her in. I must ask though, do you plan to escape or be rescued from Captain Sparrow?"

She nods her head, confirming the plan saying, "That is indeed the plan, however, it slipped my mind to think of that part. Besides having Sturdy Shield with you, I think that it would be best to have six other guards in full armor with you that can all be trusted to keep the truth a secret. The truth is that I was never a hostage and they will have to bring a carriage or wagon big enough to hold everything we will be bringing back when we leave the Black Pearl. Make sure to bring enough chests to hold Summer's belongings." Thinking about where she will be staying, she then sighs and says, "I can't believe I almost forgot to have Swift Quill start expanding the castle and add a few more rooms for guests to stay, along with building a royal storage room that only a few staff, my sister, and I have access to when she returns one day."

The pegasus nods her head saying with a smile, "I will be more than happy to do that for you, Your Highness."

Celestia smiles and nods her head slowly saying, "I would appreciate that, Smooth Flight. Thank you very much for offering, make sure that you have a safe journey back to Canterlot when you depart the ship."

Smooth Flight bows to the princess and says, "You're very welcome, Your Majesty, and we will keep watch as we head back to Canterlot." then turns around and exits the cabin to go wake up Sturdy Shield.

Gibbs is on watch and yawns from boredom when he sees the pegasus head to the carriage and looks inside before heading below, hearing a dull thunk a few seconds later followed by an audible, 'Ow' when they return as the other pegasus rubs his head. He chuckles and makes his way down to them as they start strapping themselves in to pull the carriage saying, "Fare thee well on thy journey home, ponies."

Sturdy Shield looks at the first mate and nods his head saying, "Thank you, same to you on your journeys, wherever they may lead you. Make sure to take great care of our princess while she is in your care."

He looks back at him with a smile and nods his head saying, "Aye, we will. We'll look after her as if she was one of our own."

The two pegasi then channel their unique magic to keep the carriage hovering in the air behind them and then flap their wings, watching out for any ropes that might be in their way.

Gibbs sighs happily as the two make their way from the ship, wondering if he would make for a decent father before waving the thought away saying, "Nah, I love sailing the sea, but a little fooling around won't hurt nopony."

Three weeks pass by as the Black Pearl arrives in Manetown's bustling port from Portuga, with Celestia accompanying Jack in her disguised form. Making sure that they get everything they need before leaving port as she chuckles saying, "I'm glad that they agreed to bring everything to the ship for us, that should be enough to get us through the first four months. After that, we will need to come back and prepare for the next few months."

Jack walks with her back to the ship saying, "Well that wasn't too bad for everything you got for our filly, I'm looking forward to being a father to our filly, my love."

Celestia walks down the pier the ship is docked, looking at him with a grin saying, "Oh? Well that is wonderful to hear dear, because our little filly is going to be needing a lot more as she grows up. Meaning that she will be needing clothes, more toys, bigger diapers until she gets to be twelve months old then the potty training begins."

He stops walking for a moment as what she says dawns on him and says, "Eh? Did you just say that she is going to need even more as she gets older?!"

She chuckles and looks back at him with a grin on her face saying, "Oh, didn't you know, Jack? Raising children is an expensive part of life."

Jack looks at Celestia and his daughter for a moment and swears he sees his daughter smile at him before looking at a bird as it flies away thinking, 'Oi, did...did she just...laugh at me?'

Summer Poppet's POV, three weeks ago

FYI Elizabeth is an observer at this point and has no control of the filly's body (Sorry for the long, confusing paragraphs)

Elizabeth watches through Summer's eyes as she opens her eyes briefly for a moment, catching a blurry image and dark colors with a blinding brightness that hurts her eyes, forcing her to close them again. Opening them again to see strange shapes all around her, Elizabeth watches the eyes look at a white creature with wings on her back and a horn on her head as the creature talks about her being her daughter and what names to give her. She listens as the female creature names her Summer, then hears another voice belonging to a male say Poppet. Not knowing why that voice sounds familiar until the female nuzzles her, allowing her to get a good look at who her father is a few seconds later. Seeing an all-too-familiar face looking at her wearing a tricorn hat with a red bandana under it with a couple strings of beads in his hair, smokey eyes and wearing a frock coat.

She stares at Jack in disbelief and gasps saying in the foal's mind, 'No...it's not possible. How can Jack Sparrow be my father, and why did he have to pick Poppet for my name!?' She then hears the foal cry again, sounding like a cross between a human baby's cry and that of a horse's neigh, making her think to herself, 'Just what the bloody hell is this child I'm inhabiting?!'

A few weeks pass as Elizabeth learns that the filly is a pony and an alicorn but has her wings sealed away to help her have a normal life when her mother speaks about how costly it will be to raise a child and looks at her father and says to herself in the filly's mind, 'Oh I am going to make you pay for saddling me with the name Poppet...father.'

The Black Pearl a few months later, sailing into Lost Manes on the western coast of Equestria

Jack watches the crew as they haul in the sails and toss lines to the ponies on the pier so they can pull the ship in and tie her off saying, "Alright lads, go into town and get what we need for a few more months at sea. My love and I will get what we need for the baby, then come back to wait for them to bring it all here."

Celestia holds her little filly in her arms as she stands outside the cabin breathing the sea air while the ship is tied off and a plank is laid onto the deck, turning to look up at Jack as he stands to her left on the stairs saying, "Well dear, shall we go get what we need in town? We will also need a variety of fruits and vegetables so we can get her started on solid foods because she will be teething soon."

He makes his way down the stairs and says, "Yes love, let's go fill the hold with what we will need for our darling filly. After we are done here and are on our way out to sea again, I have an idea to dispose of those diapers that are starting to pile up by the brig."

She raises an eyebrow curiously and asks, "Do I want to know if your plan is nefarious in nature?"

Jack smiles and places his hands on her shoulders as she cradles Summer in her arms saying, "I swear that no one's life will be in danger whatsoever."

Celestia watches him suspiciously for a moment saying, "Very well, you can hold Summer for a while because I need to find the little filly's room."

He reaches forth and takes Summer from her in his as she makes a funny face and feels his arm get warmer saying, "OI! Each time I hold you, I have to change your diaper. Did I do something to earn your wrath?"

The little filly just giggles at him as Elizabeth says to herself in Summer's mind, 'Of course you did...you named me Poppet! So henceforth, you are sentenced to change my diaper until I get lavatory training!'

She looks at Jack and smiles saying, "Well perhaps she does that because she likes you and is going to be a daddy's filly. Just remember to clean front to back, she is not a stallion."

Jack nods his head and says, "I did that twice, I didn't know that before, love. I will get her changed and cleaned up, where do we meet up?"

Celestia then says, "Let's meet over by the fruit vendors, we will need a fair amount. The crew can eat some of the fruit and vegetables, that way it doesn't spoil and go to waste."

He nods and then starts to head into his cabin to change Summer's diaper saying, "Aye, love, we will see you there once I finish with her."

The princess then makes her way off the ship to go find a lavatory herself thinking, 'He is definitely going to be a good father, I wonder when we should start trying for another foal...'

As Jack enters his cabin and closes the door, then sets Summer down on his table and lights a couple lanterns before getting started on changing her diaper. He then looks at her and starts humming along to a song he knows as 'hoist the colors' while changing her diaper.

The filly cocks her head curiously as he takes care of her, listening to the song he is humming. Finding it strangely comforting, she smiles and starts giggling as Elizabeth recognizes the song and sighs saying in the filly's mind, 'Really, he is humming that song to her. He is going to be a great father indeed for teaching and raising us to be a pirate.'

Several hours later, about four hundred miles south of the southwestern edge of Equestria

Jack looks ahead at a distant land he heard a few rumors about being ruled by a storm king and looks to his first mate with a grin and says, "Gibbs, come here man."

Gibbs makes his way up the stairs and stands beside Jack and says, "Aye, Cap'n?"

He looks at Gibbs and grins saying, "Let's have a little fun with the inhabitants ahead, unload the round shot from the cannons, and grab the filled diapers that are beside the brig. Wrap them in wadding and load them into the cannons, savvy?"

The first mate cocks his head and asks, "What be the point in this Cap'n?"

Jack chuckles and says, "We are going to play a smelly prank on them and also get rid of all of the accumulating diapers that are stinking up the ship."

Gibbs smiles widely and nods his head with a chuckle saying, "AYE, Cap'n! We'll give 'em a really shitty shelling, hahaha!" then goes to pass on the orders to the crew to get started.

The Storm King's Realm, at the southern port sometime during the night

Stephen Storm wanders through the southern part of the city along the docks when he hears cannons fire in the distance and shouts, "WE'RE UNDER ATTACK!! EVERY SATYR TAKE COVER!! GUARDS TO YOUR STATIONS!!" Several satyr guards rush towards their ballistae to return fire when he starts to hear wet splats all around him, not understanding what is going on until he steps in something wet and very smelly and then calls out, "DOES ANY SATYR HAVE A REPORT ON WHAT THEY ARE ATTACKING US WITH?!"

A satyr picks up a wrapper of some kind and holds it to the light calling out, "YES PRINCE STEPHEN, THEY ARE FIRING WHAT APPEAR TO BE FILLED DIAPERS AT US!"

He cocks his head and says, "They're firing what?" he is then suddenly knocked out cold when something strikes his head.

Morning comes as Stephen finally comes to with a groan and a dull headache and rubs his head groggily asking, "What happened last night..." before recalling what happened and shouts, "WHO ATTACKED US, AND WHY DID THEY FIRE DIAPERS AT US!"

The Storm King laughs heartily and says, "Stay calm, my son. They were not seriously attacking us as no one was seriously injured, they were pulling a prank is all. It was just a smelly prank, there's no need to hunt them down and bring our anger down upon them." He then starts laughing and says, "When I first learned that we were being attacked, I was about to send our fleet to sink the ship that was trying to take our home from us until I found out that they were only pranking us with used diapers. You were brought in unconscious and I thought you were seriously hurt, but the healers told me you were just knocked out cold from the diaper that hit your head. Once I learned you were okay, I laughed so hard about it all that I cried tears."

Stephen sighs and looks away in embarrassment saying, "Yeah...that is pretty funny dad. Let's get them back next time if they try to do that again."

The King lays a hand on his son's shoulder and shakes his head with a smile saying, "Sorry son, but if we do that, it may cause some issues between our nation and theirs."

On the Black Pearl, a hundred miles away from the Storm King's Realm

Celestia taps her hoof agitatedly on the aft deck as she holds Summer saying, "You did what to the Storm King's Realm?"

Jack looks to his right at an annoyed Celestia and chuckles saying, "We found a way to get rid of the diapers stinking up the ship, so we loaded them into the cannons and fired them all at the port."

She sighs and shakes her head saying, "This better not have any repercussions on Equestria's trade with them..."

He then waves his hand at the air saying, "Fret not love, it was just a harmless, but smelly prank. No trouble will come from it at all."
