“Applejack!? What happened to ya?” The concerned little foal asks. She trots over to a deformed squeaky Applejack and slows her down by tugging on Applejacks new squeaky tail. “Ah…ah’m alright sis…just….one of those days ya know?” She gives off a squeaky smile to reassure Applebloom nothing is wrong. AJ lifts her squeaky hoof and pets Applebloom on the head. “But sis, you’re so soft…that can’t be right” As she pokes and prodes her sisters new smooth body. AJ giggles slightly as the sensation and slides a bit in the opposite direction.
“Trust me sugarcube, everythin’s fine. Rarity just….cleaned me up is all. Even workin’ on a way to fix me up as we speak.” Applejack says with confidence lifting her hoof to straight out her hat only to remember she wasn’t wearing it as it slid off in the boutique. “Shoot….” Applebloom chuckles “Rarity? She can’t do magic like how Twilight can, and I’ve been learnin’ all sorts of potions from her AJ! I’ll be right back with my science pony junior kit and we will fix ya right up!” She yells out as she gallops back into the house. “No, wait Appleboom! Rarity said she’ll~~” But in an instant she was gone.
Applejack starts to imagine what her lil sis might put her through so she starts to get on all fours and slowly trot away from her hoof by hoof, making sure she doesn’t slip or else the ride might start up again. But she was too careful as she can hear Applebloom hurrying back outside with a case in her mouth smacking it down on the floor in front of Applejack as it opens up a little table with beakers, test tubes and chemicals. “Applebloom ya really~~” she gets cut off again as Applebloom feels how squeaky AJ’s hoof is and scribbles down some notes while quickly mixing two fluids together. “It’s alright Applejack! Twilight taught me how to make a dispellin’ potion! Ya’ll be back to your apple buckin’ form in no time!” The eager little sister yelled out.
A little while later and a mini puff of smoke or two, the concoction was ready. “This should help!” Applebloom stuck the potion in front of Applejacks squeaky face. Not wanting to disappoint her little sister she started to come up with excuses not to drink the potion. “That’s mighty fine of you Applebloom but I can’t drink it, squeaky hooves n all. I’m afraid of droppin’ it…” AJ can already feel the beads of sweat slide down her body. “Well, just lay back and I can feed it to ya…” Applebloom remarks. “Wut? I ain’t no baby, I don’t need nothing fed to me!” AJ starts to put on a more stern face as she carefully holds onto the potion and drinks it all up. “That’s how a REAL earth pony drinks…” AJ’s pride got the better of her as she realizes she what she drank. Applebloom with an excited face to see the result as AJ starts to feel a lot more odd than she already was.
Applejack sits on her flank and starts to rub her tummy feeling a bit more bloated than before. She starts to see her hooves get covered in some odd shiny material. They creep up her arms and legs as they are completely engulfed by them. “Applebloom! What’d ya do!” Seams start to stitch in her new plastic legs as she can’t help but laugh at how much they tickle her. “Whahahahaha…wha….when I get Rarity tahehehehe fix this you…hohohoahaha gonna get it!” Applebloom scribbles down some notes at what was happening to her sister as a little plastic valve starts to pop out of her flank. The seams travels up her body and to her arms. She can even fill the plastic seams in her mane and tail. The giggling stops as AJ starts to touch her face. It’s becoming harder and harder to talk as her head starts to turn into plastic with seams traveling up her face. Her angry face now turns into a happy smile as her mouth gets covered in plastic freezing her expression to joy. Her arms and legs stiffen into a hug like pose as the seams finish up on her ears and mane.
Finishing up the now inflatable Applejack struggles slightly but not much as she falls backwards onto the floor. “Applejack?” The younger apple pony asks her now pool toy of a sister lying there motionless.
“It’s fine It’s FINE! I just gotta try other ingredients next time!” She frantically says picking up her lifeless sister up to her room. “Big Mac and Granny can’t find out about this AJ….they’ll never let me go see Twilight and study up on potions or magic ever again! You understand right?” Applejack stays motionless with a happy expression as Applebloom comes closer and hugs her inflatable sister.
“I’ll fix ya, I promise…” A saddened Applebloom murmurs.
That certainly explains it. ^_ ^
That’s what happens to AJ in the previous picture (except Rarity’s using a magical soap instead of Kalifa’s Devil Fruit powers):
