The Book

Just another afternoon in Ponyville where Twilight Sparkle and her amazing assistant Spike the Dragon are on their weekly clean up around the Library.

"Spike? Spiiiiiiiike? You better be cleaning up there!" Twilight yells from the floor below as she is busy with cleaning the library. It was Spikes chore to clean the bedroom upstairs, which was simple enough for his pint size. Spike decided a couple of sweeps with the broom under the bed was enough to warrant a nice rest on his comfortable bed. Spike starts to hear hoofsteps trotting upstairs as he jolts out of bed grabbing the broom and starts sweeping the floor. Dazed from standing up too fast he bumps into his comic book shelf knocking the pile of comics off the shelf and onto his tiny dragon body. Twilight reaching the bedroom gives a curious look at Spike as he smiles under the avalanche of comics.

"Spike, I gave you a simple task of cleaning the bedroom, not lounge around and read comics all day." Twilight remarked with a stern voice, disappointed in his 'number one' assistant. She trots over to help him out of the pile and dusts him off from the dirty comics that were on the filthy shelf. She gives off a sigh looking at how dirty the room still was. "Spike why don't you hop in the shower and clean up while I finish up here ok?" Spike apologizes to Twilight as he shuffles off to the bathroom.

Twilight starts to clean the bedroom, fixing the bedsheets, dusting off shelves and books. Until she comes across something mysterious that was in Spikes small comic book shelf. It was a horseshoe attached to a panel sticking out slightly from the shelf. Curious she reaches in with her lavender hoof and gives it a gentle push. Much to her surprise the panel opens up revealing a very dusty book covered in cobwebs around it's binding. Twilight's eyes gleamed with surprise as she found another book for her collection. She quickly used her magic to grab it out of it's secret compartment and hold it up in the air as small dust particles fall downward. "Omygosh! A new book! Sweet Celestia I love books!" She says dusting off the dirty book and hugging it with glee.

Hearing all the noise coming from the bedroom, Spike comes back from the shower complete with towel around his waist to dry off with. "Twilight I'm so-" The baby dragon gets cut off mid sentence as Twilight uses her magic to lift Spike up and give him a big hug. "Thank you Spike! Thank you! Thank you!" Twilight yelled out in glee. Confused about the situation, Spike just shrugs and accepts the praise from Twilight. "I should be lazy more often..." Spike says in a happy manner. "This spell book was behind your comic shelf Spike! A NEW SPELL BOOK! Who knows what kinds of lost or forgotten magic this may hold!" As she caresses the face of the book, quickly galloping downstairs to her study to read what secrets the book holds.

Spike now left alone in the bedroom dries off and rightfully plops his small body back onto his bed. "Ya did good Spike....ya did good..." He stares out the window and notices how dark it's gotten outside. He starts to get sleepy the more comfortable he gets in his small bed. He starts hearing magical noises downstairs. Twilight undoubtedly trying out some of the new spells before she gets ready to hit the hay.

Spike yawns one last time as he shuffles in his warm bed, falling asleep.

Author's Note

I love reading about rubbery/latex/balloon ponies. Even more so with the Mane six as the ones being transformed. So I came up with a little story about such shenanigans. First time writing fan-fiction and I appreciate any feedback.

Pinkie Pie

"Why yes Rarity, it is a chocolate covered mansion." Said the little charming dragon with the fabulous well fashioned Rarity.
*ZAP*
A loud noise echos throughout the estate as the mansion starts to fall apart.
"Oh Spike! The Mansion! Our beautiful delicious mansion is crumbling!" The beautiful mare shrieked as she lays back on her conveniently placed fainting couch.
"I-I'll fix it Rarity!" The nimble dragon yells out, hurling himself towards the crumbling mansion as he licks the sides with his wet dragon tongue. "It's still good! It's still good!"
*ZAP*
Another booming echo resonates as the mansion starts to collapse on him.

"AH!" Spike yells out in a cold sweat, standing up right in his tiny bed with the covers across the floor.

"Just....a dream?" He murmurs to himself and sighs falling backwards onto his comfortable mattress. He wipes the sweat off his forehead while looking at the window outside. Just another sunny day in ponyville as the birds are singing to the beat of a new day. He gets up to stretch and walk to the side of Twilight's bed.

"Morning Twilight!" the ecstatic assistance says with enthusiasm. He peeks over and notices Twilight wasn't in bed! She even fixed the sheets before she left the room. Curious about the situation and if she made breakfast for him, he scurries over on downstairs to greet her on a new morning. While walking down the stairs he hears a familiar noise he swears he heard somewhere before.

*ZAP*

Spikes scales stand on end as he barely remembers the dream he JUST had, but remembers the noise all too well. "T-Twilight?" He softly walks on each step trying to reach her study on the first floor and sees the purple lavender levitating the new book she found and quickly writing down notes next to her.

"Yes.......yes this is a most certainly funny book...." She says to herself as she giggles about the results. Clueless, Spike reaches the last step as he starts to notice something off about the floor. Instead of the recognizable hard wood of the floor, now it feels like a trampoline or a bouncy house. He loses his balance and falls on the soft squishy surface. "WOAH!" He yells out, alerting Twilight. She turns to face Spike and helping him up.

"Spike? What are you doing up so late? It's way past your bedtime you know...." Twilight concerned for Spike.

"Late?" Spike says. "Twilight it's morning, have you been doing..." He gets cut off mid sentence as he tries to keep his balance on the soft floor, pointing downward with a confused look. "THIS!?"

Twilight giggles "Oh my...have I been doing this all night?" She quickly levitates all her notes she has been jotting down, enough notes to make a whole other new book for her collection on the recent findings of the spell book and it's possibilities. Spike stares at the impossibility of what she managed to do in one night with his jaw opened. He stares at the other objects next to her notes. Everything looks smooth and shiny as they reflect off the sun shining down on them through the window.

"Uh, Twilight? Just what exactly did the spells do?" He asks.

"That's a very good question Spike! Allow me to demonstrate!" She starts to levitate an apple towards spike. "Here! Try this shiny red apple!" Twilight says handing him a peculiar shiny red apple. He doesn't notice at first but as soon as he grabs it with his claw he notices the apple is more squishy than usual. He tries to take a bite out of the apple but as soon as his pointy teeth sinks in a loud popping noise echos throughout the room.

"BLEH, Twilight what the heck! That tasted like rubber!" Trying to wipe his tongue of the disgusting taste while picking up the pieces of the exploded apple. Twilight just stands in place giggling.

"Well maybe it would be funnier tricking other ponies than baby dragons with super sharp teeth." As she gently pats Spike.

"So, what just happened? You made me pop a small balloon?" Holding the remains in his claw as Twilight swayed her head.

"No silly, that really was an apple! The spell made it turn into a super soft and squishy poppable apple!" The lavender pony starts giggling at the hilarity of it all while explaining.

Spike gave a stern look towards her. "You mean rubber?"

"Well to be more precise the book specifically states these are latex spells, natural rubber from actual plants and trees...." The smart unicorn pony starts to give off a lecture to Spike about natural rubber and it's uses around Equestria. He starts to zone out, unable to stand still on the squishy floor he just sits down and tries his best to pay attention.

15 MINUTES EARLIER

"Oooh oooh oooh! They're almost ready! They're almost ready!" Pinkie Pie sings as the cupcakes are being tipped off with frosting by Mrs.Cake at sugar cube corner.

"It's the least we can do for Twilight and her little dragon friend for helping our favorite helper around the shop Pinkie!" Mrs.Cake quickly closing off the box of a dozen cupcakes with a thank you note to Twilight and Spike.

"I know right!" Pinkie screams outloud. "I can handle one or maybe to Pinkie's, but there was just TOO MANY OF ME!" She remembers the event with the mirror pool and the little accident Ponyville suffered from her careless mistakes in summoning too many versions of herself. "I'm really happy to have made these for Twilight, shes a good friend ya know?" Pinkie facing Mrs.Cake with a smile.

"Oh deary, I am sure she is" As Mrs.Cake places the box carefully on Pinkie's back. "Now run along before these babies get too cold!"

"Yes Ma'am!" Pinkie gives off a salute before leaving the bakery and trots over to Twilight's house.

20 MINUTES LATER

"Twilight you're lecturing again!" Spike yelled out-loud, having enough of the smarty pony's lesson on latex and rubber. Twilight comes back to her senses and finishes off quickly.

"In conclusion I have found out the varied uses of this method of transforming one object into another has many multiple uses of daily life around ponyville and can benefit pony kind to make life easier." A little squee can be heard as she finishes with a smile. A bit of skepticism arose within Spike. "I dunno Twilight, how does making the floor squishy or turning an apple into rubber benefit ponies?" Spike says standing up, wobbling about.

"Oh Spike, I don't intend on leaving it like this." Twilight's horn flares up, zapping each of the rubbery items on the desk, returning them to their normal sturdy forms. She lastly zaps the floor with rubber removal spell as it shifts and squeaks back to its normal wooden floor. "There see! Back to normal, no need to worry about anything Spike." She trots over to her number one assistance and hugs him. Spike feeling a bit left out with discovering the spell starts to wonder if he can see the spell in action.

"Um, Twilight? Do you mind if you cast the spell one more time? I just wanna know what it looks like is all..." Spike digs his foot into the ground being left out on the fun and exciting new spell.

Twilight giggles and hugs Spike. "Of course, just make sure it's an object. I wouldn't want to think what would happen if a living pony or dragon was turned into latex." The sudden realization that something could go wrong sinks in with Spike but Twilight reassures that she has the spell practiced and handled if something went wrong. Spike takes that as an OK and walks over to the kitchen to grab an orange from a fruit bowl and walks back to Twilight.

"How about turning this orange into a rubbery orange?" Spike says placing the spherical orange on the table. A slight nod from Twilight gives him the sign to stand back as Twilight beings to work her magic. She feels confident enough to not use the book as a reference as she recites the spell by heart. Her lavender horn starts to give off a warm glow as she charges up the beam. Haven't slept a wink in more than 24 hours her eyes start to get blurry as she tires to focuses them on the orange.

*DING DONG*

Twilight's heart skips a bit from the doorbell ringing and fires the spell missing the orange completely as it ventures into the kitchen. The beam starts to reflect off smooth shiny surfaces pinging and banging across every which way. Twilight quickly grabs spike and they both duck underneath the table hoping to not get struck. What lasted for a mere 10 seconds was an eternity for both of them as the spell quickly exits the house via an open window, reflecting off a certain mail-mares mail cap aimed directly at Pinkie Pie waiting outside the front door.

*ZAP*

"YEE-OUCH!" The party pony yelled outside. "Dumb bees! These cupcakes aren't for you!" She keeps on yelling and flailing her arms to shoo the honey bees away from the box. Twilight and Spike both rushed to the front door as Pinkie keeps on ringing the bell again....and again, once more even though the door was open. Pinkie finally notices them in the door way.

"MORNING TWILIGHT!" She says as while trotting inside and gives Twilight a big hug. A couple of bees were heading inside as well but Pinkie slams the door shut before they came any closer. "PHEW, those are some suborn bees, I think one of em stung my BEE-hind!"

*BU- DUM-PSH*
An awkward noise came out of nowhere as Twilight and Spike looked at each other in confusion.

"Well don't laugh all at once guys..." Pinkie said giving off a happy smile. Twilight couldn't help but laugh at the silly pony as she giggles.

"What brings you over to the Library Pinkie Pie? Need another cook book?" Twilight said resting a bit on the floor.

"Aw nah, nothing like that today Twilight. I brought yummy treats for you and Spike! A little thank you gift for helping me with me....*ahem* Pinkie problem a couple of weeks ago." Pinkie said, laying the cupcakes on the table nearby. "Mrs.Cake told me strictly to not eat one cup! Or one cake! These are all yours Twilight!" She stood up proudly as if she was awarding Twilight a medal of honor. Twilight looks on rubbing her eyes, trying to stay awake during Pinkies thank you gift presentation as he vision gets blurry.

"Heh, thank you so much Pinkie. Spike....*yawn*..... and I really appreciate it." The lavender pony softly dozes off in between sentences, resting while she had a guest over. Pinkie takes notice and nudges off to Spike.

"What's wrong with her?" Pinkie asked in a silent tone.

"Aw she just stayed up all night working on a neat spell, she should really get some rest Pinkie." Spike slowly nudges Twilight's shoulder and to not startle her. Twilight wakes up from the short rest.

"What is it Spike?" Twilight spoke, her eyes trying to adjust on her number one assistant.

"I think you should get some sleep Twilight. You've been at it this whole night. Please get some rest. Please?" Spike said, concerned with the Twilight's health. She softly nods and stands up right. Spike holding on to Twilight's hoof assists her in getting upstairs and tucking her into bed.

"But Spike, what about the....*yawn*.....spell....." Twilight murmurs as she falls asleep quickly now in her comfy bed.

"Don't worry about it Twi, you can show me another time ok?" He gently pats the ponys head as Twilight is already fast asleep. He gently closes the bedroom door and meets up with Pinkie Pie on the first floor.

"Awww, I was hoping we could hang out today!" Pinkie said plopping her rump on the floor a bit saddened she wouldn't be able to see Twilight enjoy her cupcakes.

"Well uh, I'm free Pinkie!" Spike says walking up to the depressed pony. As he does he hears his tummy rumbling from not eating breakfast yet. He hold his stomach, slightly embarrassed by the loud noise he gives off. Pinkie's ears perk up as she hears the troubled cries of an empty stomach.

"Ya hungry Spike? I can whip you up something delicious back at Sugar Cube Corner!" Pinkie said bouncing up and down rapidly on the floor. Her eyes flare up as she sees an opportunity for a super fun hang out time with her super friend Spike the Dragon!

"Uh sure Pinkie!" The dragons voice escalated to the same level as Pinkies enthusiasm, taking up her offer to cook him some free food. "Just let me tell Twilight really qu-" He gets cut off as Pinkie flips Spike over her head and onto her back.

"Let Twilight sleep silly, you're with auntie Pinkie Pie now. You have nothing to worry about." She says while patting Spikes head. She trots over to the door. Concerned about his friend, Spike halts Pinkie Pie.

"What about your bee sting Pinkie? Shouldn't you head on over to the hospital to get that checked out?" Spike said. Pinkie does a little twirl in place wondering where that stinging sensation went. She looked all over her body but couldn't see a single sting. She brings her pink hoof to her flank and gives it a rub.

"I was sure those meanie bees stung me right here...." Pinkie said as she strokes her flank and pushes her hoof against it to make sure it didn't hurt. After the inspection she gives off a shrug to Spike as they both exit the Library and softly closes the door. Trotting over to Sugar Cube Corner she happily hums a happy tune in her head. "So what kinda fun stuff were you guys up to?" Pinkie asked.

Spike eyes lit up as he was just as eager to tell Pinkie Pie what new spells Twilight was up to. "Twilight found this really old dusty book behind my comic book shelf and it had a couple of new magic spells in em!" The little dragon couldn't contain his excitement. "You should have seen it first hoof pinkie! The floor was like a bouncy house and Twilight tricked me into popping an apple!" Pinkie Pie giggles at the joke Spike was trying to tell.

"Bouncy house? Twilight pranking? That doesn't sound like her at all Spike." Pinkie said as she giggles some more at the absurdity. "Besides Spike I was there! The floor wasn't bouncy at all! I tried. Trust me." She said in the most confident voice Spike ever heard of Pinkie Pie. Spike starts to bap his feet onto Pinkie's haunches.

"But it's true Pinkie! She found the spell book and I fell asleep after my shower! When I woke up she was turning things into rubber! I couldn't stand up straight on the floor!" He exasperates his last breath trying to explain the odd morning to Pinkie Pie, slumping all over her back resting his tiny body. Pinkie Pie merely looks behind and pats his head, still trotting over to Sugar Cube Corner.

"You must be hungrier than I thought Spike, ya start hallucinating about bouncy floors and fruit that pop when you try to eat them!" She gives off a couple of snorts and laughs while teasing Spike.

"Ughhhhhhh!" Spike moans outloud; giving up on trying to convince the pink party pony on what happened that morning.
*grumble grumble*
"I should have eaten a cupcake before we left, are we close to Sugarcube Corner yet?" Spike asks desperately while holding his dragon tummy.

"Don't be silly Spike! Those are cupcakes for dessert! What you need is a healthy delicious breakfast cupcake! I'll whip you one up in no time!" Pinkie yells out excitedly.

As Pinkie Pie trots over to Sugarcube Corner her tail starts to puff out slightly, crinkling and squeaking about as a shiny coating starts to envelope her tail. The hairs of her tail flatten against the surface, turning her once furry tail into a poofy squeaky soft tail. Neither pony nor dragon takes notice while Pinkie Pie giggles her way to the sweet shop.

Author's Note

The changes are coming, albeit a little slowly. She's getting there though and I cannot wait. c:
As always, please give any feedback.

Rubbery Pie

Pinkie Pie finally reaches Sugarcube Corner, opening the door with her hooves as she trots in to see Mrs.Cake heading upstairs after cleaning the kitchen. She shakes her rump a bit to wake up a certain sleepy dragon taking a rest on her back. "We're here Spike!" Pinkie whispers loudly towards at him as she picks up the sleepy Dragon and seats him at the counter. Pinkie Pie trots away from him and heads towards the kitchen for his breakfast cupcake. "I'll be back in a jiffy!" Pinkie says.

Spike rubs his eyes as he sees Pinkie's tail looking differently, the light reflecting off the tail is almost blinding him. Before he could speak a word out his tummy grumbles once more as he moans. "Ooooh, Dragon needs food badly....." Spike plops his head down on the counter waiting for the party pony to being back his much needed food.

Inside the kitchen Pinkie Pie prepares his amazing breakfast cupcake. "Oooooh! Mrs.Cake left some baked cupcakes in the oven!" She yells out happily and takes pieces of waffles and pancakes as she chops them up in a bowl. Carefully adding whip cream to the cupcake and sprinkling the bits onto the cream. She trots to the refrigerator and takes out a bottle of syrup and a cherry as she closes the door with her rump. Her rubbery tail gets caught in between the fridge door hearing a loud squeak. Pinkie's ears perk up as she hears the squeaky noise but thinks nothing of it and trots over to the counter to finish her masterpiece.

"Add in some delicious syrup and a cherry for the finish!" She squirts out the syrup rapidly on the cupcake and carefully places a cherry on top. "PERFECT!" She yells outloud. Trotting further and further away from the fridge towards Spike as the fridge door holds on to her tail farther and father until suddenly a loud snap could be heard.

*SMACK!*

"YEEEOWWWCH!" Pinkie yells outloud as she flings up the perfect breakfast cupcake upwards and landing in messy pile in front of Spike.

"Ugh, finally!" Spike says as he wraps his dragon tongue around the mess and swallows it whole. *munch munch* "Ahhh, much better...." He says rubbing his tummy in a gleeful manner. "Thanks a lot Pinkie!.......Uh....Pinkie?" He asks as he takes a peak over the counter towards the kitchen. He sees Pinkie Pie rubbing her flank from the snap of her rubber tail smacking her on her rump. "Oh no! Is the bee sting acting up again?" Spike asks.

"No no...I'm fine. Just something hit my little hiney." She says while rubbing her flank with her hoof. She could see a reddish hue on her pink flank where the smack landed. Pinkie then does a quick twirl around her to see what had hit her. "It felt like a rubber band smacked my rear while I was in the kitchen..." She says very confused like, examining the floor for anything that could have hit her but found nothing. She shrugs it off while trotting over to Spike. "So how did you like my Breakfast Cupcake? Pretty good riiiiiight?" She nudges her elbow at Spike while giving off a friendly wink.

Spike licks the delicious messy table, cleaning it very quickly with his tongue. "It sure was! Thanks Pinkie!" He says while resting on the stool, giving of a loud flamey burp. Pinkie giggles as she sits next to him, a long squeak can be heard as she sits down on the floor, her back then starts to recline against something soft as she struggles with the squeaks continuing. Spike peers at Pinkie Pie leaning against what looks like a plastic chair. "Uh, Pinkie, where'd you get that?" He asks pointing at what shes sitting on.

Pinkie stares behind her and notices the funny looking chair she's sitting on. "OH MY GOSH! The Cakes took my advice! See I told ya this place would look better with bean bag chairs!" She starts squishing the chair with her rump to get extra comfortable. *squeak squeak* She reclines further into the funny squeaky chair as she lifts her hooves up in a relaxing manner.

Spike jumps off his stool, curious about the very comfortable bean bag. "Hey let me try it!" He says poking the squishy chair. Pinkie nods as she gets up and trots away to have Spike sit on the funny chair. But then Spike sees the puffy bobbly chair shrink in size as Pinkie trots away with it. "Hey Pinkie! I asked to let me have a turn!" He says grabbing the Pink plastic chair.

At that moment Pinkie feels a slight tug on her rump as she looks behind seeing Spike stretching out her tail farther and farther away from her. "What the.....Spike!" She yells loudly. Surprised, Spike loosens his grip on her rubbery tail and lets go. It snaps back loudly smacking her rump yet again. "YEEOOWWCHH!" She yells out jumping in place as she cares for her tender behind. "Spike! Why'd you do that!?" She says with tears welling up on her eyes.

"You were taking the bean bag chair! I wanted a turn!" He says as he looks directly at the pink poofy bean bag. Inspecting it more cloesly he sees the chair connected to Pinkie's rump. *GASP* "That's no bean bag chair! Pinkie, that's your tail!" He says excited like as he pokes her latex tail. Pinkie gasps along side Spike as she twirls in place, looking at the poofy tail follow her every movement.

"PORTABLE BEAN BAG CHAIR!" She yells outloud, jumping up and landing on her poofy tail without hurting herself. She giggles and snorts as she squeaks about on her rubbery tail. Spike attempts to snap Pinkie out her excitement.

"Pinkie! This is serious! Remember what I told you while coming over here? Twilight's spell must have hit you by accident!! You're going to turn all rubbery!!" The baby dragon starts to get nervous thinking of what might happen to Pinkie Pie. The sounds of the apple popping from this morning starts to echo in Spike's head. Louder and louder it gets as he snaps out of it. "GAHH! WE NEED TO FIND TWILIGHT QUICK!" Grabbing the relaxing equine's hoof as he struggles to pull. "HNGGG! Come on Pinkie! I'm serious!"

Pinkie Pie just relaxes and giggles as she pats the baby dragons head. "Oh Spike, there's no need to rush! Twilight is super duper smart! I'm sure she knows how to fix this anytime she wants! Just let her rest for now, besides I'd like to surprise her with my new squeaky tail chair bag!" Squeaking her tail as funny noises come out. She laughs out loud, giggling to herself.

Spike continues to tug her hoof but eventually slips his grip. He notices her hooves have been glossed over, getting shinier and smoother as time passes. Seeing each of her hairs bend over and staying flat against her body as she gets progressive with her transformation. "P-P-PINIKIE YOUR HOOVES!" Spike yells out, alerting Pinkie to lift up her now squeaky hooves as she squeaks against her rubbery tail, letting out a giggle as the sensation tickles her. "Hehehahahaha"*Snort*

Pinkie stood up slowly as she can feel her hooves slip and slide against the floor. "Woah! This is hard!" She giggles trying to maintain balance, squeaking every time she trots. She eventually uses Spike as a prop to stay balanced. Spike can feel her arms and knees starting to get rubbery as well, shining against the light, slowly creeping up all over her body. "Ok Pinkie enough fun! We have to go see Twilight! It's getting worse!" He says grabbing her hoof and squeezing it with minimal effort. "YOU'RE TURNING INTO A RUBBERY PONY PINKIE!" Spike yells out with tears welling up in his eyes. Not wanting to see his best friend pop just like the apple, Spike leans in and hugs Pinkie. She opens up her mouth and squeaks the longer Spike keeps on hugging her. *Squeeeeeeeeeeeeeak*

Realizing this is serious situation she hugs Spike back. "Ok ok, no more games. We can go see Twilight...don't cry Spike..." Pinkie says as Spike lets go of her. "*SIGH* "Finally..." Spike relived that Pinkie would listen to reason. "I just have check up on the twins, Mr.Cake is out on business and Mrs.Cake must be really tired from helping me this morning with the cupcakes." Pinkie says trotting away towards the kitchen, sliding on her new hooves and slipping onto the floor with a soft squeak and quickly getting back up. "I meant to do that..." She continues trotting away.

"Pinkie we have to go now!" Spike yells out following the pink pony into the kitchen. He sees her mixing up some baby formula, letting the bottle slide from her hooves, making a mess while trying to pour the formula. It was hard for Spike to see. "Ugh, just let me do it Pinkie!" Spike says grabbing the baby bottles and cleaning them off. He pours the right mount of formula into each bottle and warms them up.

Pinkie stares at herself in the reflection of a shiny pot while Spike prepares the bottles for the Twins. She notices how poofy she looks now, her flank and belly now covered in the smooth substance. Unable to see fur anywhere she is only met with squeaks as she passes her hooves by. She gives her behind a squeak and notices her Cutie Mark affected by the changes. Her balloons now perfect balloon circles with a shiny reflection on them. She squeaks to herself wondering if she should be worried. "On the plus side, this makes me feel really giggle....but on the other squeak hoof I can't hold onto anything without slipping everywhere...." She sits on the floor reclining on her tail wondering about the situation.

Spike finishes up and walks over to Pinkie. "There, let me just give it to them and we..." Spike gets cut off as Pinkie's squeaky hooves covers his mouth. Standing up she takes both bottles in her hooves. *Giggle* "Silly Spike, they're just babies. Having a big dragon come in their room would terrify them..." She says as the bottles immediately slip out of her hooves while still smiling. Spike smacks his head and picks up both bottles off the floor. He quickly grabs Pinkie's hoof leads her to upstairs in front of the Twins room. "Here, just use your mouth to hold these." He says stuffing both bottles between her teeth. Spike examines Pinkie while getting her ready to feed the twins quickly. "Ohhh! This isn't good, it's covered your whole body Pinkie! All is left if your head..." Pinkie attempts to speak with her mouth full. "Mmmmmoooph?"

*FWOMP*

Spike's jaw drops as in an instant he sees Pinkie's hair becoming rubbery, flattening against each other as it gets shiny like the rest of her body, eventually leaving a poofy mold of her manecut on top of her head. Spike swings the door open to the Twins room and shoves a very light Pinkie in there. "HURRY!"

Pinkie trots carefully towards the crib and gently nudges the baby ponies to wake them up. She squeaks her neck down onto the bed to carefully place the bottles next to them. "Wakey-wakey Pumpkin and Pound Cake. Time for your delicious dwinks!" The twins start to wake up as they crawl to the edge of the crib to hug their squeaky caretaker.

"Ponapie!" Pumpkin says
"Pankpoe!" Pound says

Pinkie chuckles to herself. "Come on guys, you got it right once..." She lowers the crib cage and sits on her poofy tail to feed them quickly. The twins sit gently on her squishy body relaxing at how soft Pinkie is. Suddenly she feels a tingly sensation on her face, scrunching and wiggling her nose she felt her face becoming rubbery as the spell progresses. Tasting the rubber in her mouth, squeaking her tongue about and not enjoying the taste at all. "Bleh....Twilight really needs to fix this spell....make it more delicious*squeak*" Blushing as she lets out a squeak, baping her soft hooves to her squeaky chest she clears her throat. *AHEM*

"*Squeak!*" Pinkie says yet again, narrowing her eyes towards her snout, she could see and feel the rubbery spell cover the last bit of her fur.

The twins then look up at Pinkie, giggling at the funny noise she made. Pumpkin finishes her drink first as she slips and slides over Pinkie's squeaky body having fun. Pinkie tries to hold on to Pumpkin but her new squeaky hooves can't get a good grip. "*Squeak squeak!*" Pinkie says outloud as she finally caught Pumpkin chewing on her soft hoof.

"nom-nom-nom" Pumpkin says while chewing on her squeaky foalsitter. Pound sees Pumpkin having fun and starts to bap his hoof on Pinkie's stomache. With each bap Pinkie is forced to let out a squeak from her mouth. "*Squeak*" "*Squeak*" "*Squeak*" Pound waves his hooves up in the air and giggles in delight at the noise coming out Pinkie.

"*Squee squee, Sssqueaky squeak squeak....*" Pinkie says while trying to contain the two with her soft hooves. Pound and Pumpkin look at each other and giggle, crawling out of Pinkie's grasp. The two tiny cakes easily overcome Pinkie, munching on her squeaky hair and bapping every inch of her rubbery body.

<"Oh no this is bad! I don't have any strength as a squeaky toy! Um....pony! I meant pony.....right?"> Pinkie squeaks to herself as Pound keeps on bapping her stomach. The noise she produces makes her giggle uncontrollably as her eyes begin to sparkle, feeling more bubbly and giggly than usual. Pinkie spots Pumpkin chewing on her rubbery mane and quickly hugs the foal. <"That's right! Squeaky toy Pinkie will play with you!"> Pinkie squees in delight squeaking and playing with the cake twins on the floor.

"Pinkie are you done yet? We gotta go..." Spike says walking into the nursery room. He gasps seeing the cake twins chewing and squeaking a now fully rubbery Pinkie Pie. "Pinkie I know you love playing with them but we gotta fix you!" Spike says grabbing Pinkie's hoof and walking towards the door. A stretching noise can be heard as he touches the knob to exit.

"*Squeak!*" Pinkie squeaks out as she stays in the same spot having fun with the foals.

Spike looks back, a bit alarmed at how far Pinkie's arm can stretch. "That does it, Pinkie you are coming with me one way or the other." Spike says stretching her hoof out the room, down the hallway, down the stairs and eventually out the front door. As the shiny pink plastic rubber contorts it's way through the house, Spike continues tugging her hoof. Eventually he loses his grip as Pinkie's hoof travels back to the nursery room quickly and snaps back into place. Spike tumbles outside, a bit dazed he shakes it off as he hears happy squeaks and giggles coming from their open window on the second floor. "Oh no it's getting worse! She doesn't wanna leave! I have to get Twilight to undo this or else who knows what those two brats might do to her!" He starts to imagine the cake twins playing too rough with Pinkie Pie until eventually...
*POP!*
Spike jumps up in a panic and rushes off home to alert Twilight.

MEANWHILE AT THE GOLDEN OAK LIBRARY

The door quietly opens as a mysterious figure trots into the living room. "Hello, is anypony in here?" The unknown figure calls out into the quiet house, waiting for a anypony to respond back but she is met with silence. "Well I'm sure Twilight left me it somewhere.......Ah this must be it!" A blueish aura starts to envelope a familiar book, levitating it straight to her saddle bag. The mysterious unicorn trots outside, closing the door behind her and hums a tune.
