"....Actually, this might work in my favor." Twilight said to herself as her ears perked up. "Yes Pinkie Pie I'm down here!" Twilight shouted back up.

The two dragons nearby were slightly startled to see Pinkie Pie barrel down into the basement, although that wasn't too unusual, the reason was different for each though. Spike was surprised Twilight would want Pinkie interrupting things, while Apple Bloom was embarrassed to have another pony privy to her issue. Of course both reacted in the way you would expect when Pinkie Pie got near the three of them.

"Oh hey, Twilight, Spike, other dragon I've never met before!" Pinkie Pie went on before gasping as she looked at Apple Bloom, after which she got a little green in the face as she mistakenly breathed in a lung full of the horrendous odor.

Spike giggled quite a bit as Pinkie Pie coughed and spluttered, waving a hoof in front of her face, while Apple Bloom merely covered her face with her claws, hiding her embarrassment.

"Woah! That's quite the odor!" Pinkie Pie exclaimed as she recovered.

"Yes, it is isn't it Pinkie. Now that you're here, why don't you lend me a hoof with changing their diapers." Twilight mentioned with a somewhat smug look upon her face. While Pinkie was often annoying at the best of times, having the mare here now would prove quite helpful.

"Aw geeze, looks I picked the wrong time to drop by! But sure, I'll help you Twilight." Pinkie Pie said, not one to back down from helping her friends, even if it meant such disgusting work. "But I call dibs on the new dragon!" She added as she went over and pushed Apple Bloom onto her back.

Meanwhile, Twilight went over towards Spike, pressing him down onto his back much like Pinkie Pie had done for Apple Bloom, Twilight levitated the needed supplies over to them both and began to relatively usual chore of cleaning up Spikes mess.

While just a few feet over, Pinkie Pie began doing the same for Apple Bloom. "So, what's your name?" Pinkie asked as she then moved her head in and grabbed the tapes of the diaper in her mouth, pulling them apart.

Apple Bloom uncovered her face for a moment and looked at Twilight for help. Since she wasn't sure if she should tell Pinkie. But Twilight caught on immediately.

"It's alright, that's Apple Bloom Pinkie, she messed with an unknown potion and ended up turning herself into a dragon. I planned on telling you and the rest of the girls at least, but we need to keep this a secret from everypony else. If word gets out that ponies are turning into dragons, that could have some interesting consequences, and we'd definitely prefer to not let anypony else know until we can reverse the effects." Twilight explained while her magic levitated wipes and pulled the dirty diaper off of Spike.

Pinkie Pie felt a shivering in her left hoof and turned to Twilight. "You might wanna-" but was unable to continue the statement as Spike's bladder sprung to life, spurting urine towards Twilight's face, only for it to be grabbed in her magic and safely streamed into the dirty diaper.

"I've changed him before Pinkie, I've got this." Twilight added.

Apple Bloom's diaper was then opened up by Pinkie, since they were on the floor Pinkie managed to use one hoof to help get Apple Bloom cleaned up, but she still used her mouth as well, using both to effectively wipe the little dragon clean. Thankfully, unlike ponies, dragons had scales which were wiped remarkably easily, and after a few strokes, both Apple Bloom and Spike were nice and clean.

The new diapers were put in place, powder was added, although Pinkie Pie practically drowned Apple Bloom's waist with the stuff, and their diapers were taped up practically at the same time, both of them sporting the same plain jane design, which Apple Bloom was thankful for, the idea of wearing an overly frilly thing would have just made this worse.

Once they were diapered up, and their tail tapes were secure, the two of them stood up as they were checked to make sure the diapers were properly set. Pinkie Pie gave the back of Apple Bloom's diaper a light swat, causing a puff of powder to blow out of the back of it. The air was saturated with the smell of foal powder, though the underlying scent of dirty diaper was still there, but quickly went away as Twilight teleported both diapers out of the room, likely into the nearest diaper pail.

Immediately after that Pinkie said. "So I can't throw a 'You've turned into a Dragon' party?" giving Twilight that big puppy dog eyed look.

Twilight shook her head though. "No, you can't Pinkie. But maybe you can throw a party for when we turn her back to normal." 'If we turn her back to normal.' Twilight thought to herself as she stood there.

"Well, I need to look more closely at that blood sample, and you two, can get to work." Twilight mentioned as Spike stood up.

"Come on Apple Bloom, let's go clean up the library." Spike said as he helped Apple Bloom to their feet. The two of them began to slowly toddle back upstairs, with Spike helping Apple Bloom to walk.

Once they were gone Pinkie turned to Twilight. "So, you're just going to have them clean things up? Nothing new?" she asked.

Twilight nodded. "Yes, but I actually have something for you to do too Pinkie. I need you to go to Rarity and Fluttershy, and ask them if they can watch those two."

"I can watch those two!" Pinkie cut in.

"Yes, I know that Pinkie, but Rarity and Fluttershy have spent enough time around Spike that they should be able to handle both him and Apple Bloom, especially since Apple Bloom could have different issues. I'm not saying I won't ask you to look after them sometime soon, but I need some ponies with more dragon experience watching them, and I need them out of here so I can completely focus on fixing Apple Bloom, I won't get much done in that regard if I'm changing twice as many diapers." Twilight told her.

"Oookay!" Pinkie Pie said as she was about to race off, but before she could, Twilight grabbed the party ponies tail in her magic.

"Now, I need you to Pinkie Promise you won't tell anypony but the girls, and if you tell Rainbow Dash you have to make her Pinkie Promise not to tell anypony else either." Twilight stated.

"Cross my heart, hope to fly, stick a cupcake in my eye." Pinkie recited, while doing all the proper hoof gestures.

"Good." Twilight said as she let her magic fade, and that caused Pinkie to launch off like a rocket, clearly she was eager to tell her friends what had happened. While Twilight went back to her equipment to run some tests.

Twilight wondered how long it might take Pinkie Pie to return from doing that, but knowing Pinkie it would be right around the time Twilight needed the responses from her friends. In the meantime, she got to work.

Upstairs the two dragons got to work cleaning the library. Or rather, one of them did. Spike was an expert and knew where everything went and how to carry it all, Apple Bloom still had trouble walking properly, and was taking her time just trying to get steady on her feet. Spike was helping her too, in fact he was doing the cleaning faster than usual, so he could spend the extra time helping Apple Bloom cope with her new body.

"It shouldn't take you that long to get the hang of it." Spike told her.

"Well, it's less of that, and more that I just wanna walk like this." Apple Bloom said as she began walking on her hands and feet, like she would have as a pony. "But this is really uncomfortable."

"Yeah, I think I used to do that when I was really little. I think you just need some motivation." he told her as he left for a moment, he was back almost as quickly as he'd left. Except he was holding out a small piece of topaz. "If you can walk all the way from the back of the library to the front, without falling or grabbing anything for support, you can have this." he told her.

Apple Bloom looked at the gem and licked her lips reflexively, she knew how good gems tasted when she was a dragon, and if that amethyst was any standard, then the topaz would be just as good, if not better. With that in mind, she resigned herself to learning to walk properly. Which took the better part of the day, by the time it was a little past lunch, Apple Bloom was making her way across the library.

"Come on.. Come on.." She said to herself as she moved carefully across the floor.

Spike was watching her walk, he'd finished a little bit ago and had mainly switched to helping Apple Bloom, telling her how to walk properly with her diaper on.

Apple Bloom was inches away from the front door when it suddenly burst open, causing her to fall back in surprise.

Pinkie Pie bounded through the door, rushing past the both of them, and making her way into the basement. Spike rushed over and helped Apple Bloom back to her feet.

"Shoot, I was so close too!" Apple Bloom said in frustration.

"Well, I think you would have made it anyway, so here." Spike said as he gave her the gem.

"Awe, thanks Spike!" Apple Bloom then tossed the gem into her mouth where she eviscerated the gem with her razor sharp teeth. The lovely taste of it sending a wave of happiness throughout her body, feeling a gentle warmth at her crotch, though a slight giggling from Spike brought her back to reality.

"What's so funny?" Apple Bloom asked.

"Well, now your diaper matches the topaz I gave you." Spike pointed at her diapers front, which was now stained with a yellow splotch that spread from the middle outwards.

"Ugh.. And Twilight won't change it until I use it way more.." Apple Bloom sighed to herself.

"Well that's probably true, maybe you can convince Pinkie to change you again, let's go see what she's here for by the way, she rushed right past us!" Spike told her as she grabbed Apple Bloom's hand, pulling the girl along to the basement, Apple Bloom managing to finally stay on her feet while moving at a faster pace.
