“So, how long is this going to last? I don't exactly see either of you having me turned into a pony forever.” Nickel Ingot paced around the conference room in front of Celestia and Luna, his deep voice echoing ever so slightly off the walls.
Luna raised an eyebrow at the rather impressive, chiseled stallion in front of her. Whoever Celestia asked to arrange this transformation certainly knew what they were doing. “Art thou sure about that, Nicholas? Oh, our apologies. Art thou sure about that, Nickel? Thine new body is rather dashing, thou would certainly be a… what was the word thou used... ‘ladykiller’ here with a physique such as that.”
“Luna's right, you know,” Celestia butted in. “As far as earth ponies go, you are very attractive as one. If I were a mare your age I'd be all over you, but neither I nor my sister think we could handle the emotional trauma of losing a lover. Unfortunately, that leaves only Discord for the time being…”
“...and we would rather spend another millenia on the moon than be his betrothed,” Luna finished.
Celestia shrugged with her wings. “Regardless, I did not allot much time for this meeting, I just wanted to see that you were doing alright. I have a meeting with my physician in thirty minutes. Even alicorn princesses need check ups, after all.”
“Oh. Is that today?” Unaccustomed to pony mannerisms, Nick displayed every equine tell that he was suddenly stressed. “Well, I won't keep you. I better get going, I have very important pony things to go do!” Nick hastily wobble-walked out of the room, leaving the two sisters giggling at his antics.
“Dost thou think he tried to sabotage thy appointment? We doubt he would do that to thee.”
Celestia grinned smugly. “I suppose I'll need to go find out, won't we?” She trotted out after Nick, quickly turning towards her chambers for her upcoming appointment.
Doctor Cross gave Celestia a big smile as he finished his examination of her. He always enjoyed house calls. Or, in this case, castle calls. “Well, your majesty, you seem to be in perfect working order! Healthy heart, no breathing problems, bone density is well within the average for a pony your height…”
The solar diarch put on a obviously fake concerned look. “So I'm not going to die in my sleep and never have to touch paperwork again? Oh, Doctor Cross, I don't think I can handle the stress of work anymore!” She held a hoof to her eyes and leaned back in her best impression of an upset Rarity, and stayed still for a few moments. Silence permeated the room until she opened one eye and stared at the bespectacled brown unicorn. “Really? No concern at all?”
“Your majesty, with all due respect,” he began, finishing his notes and moving his clipboard out of the way. “I have been seeing you as a patient for twenty-five years, and not only have you been nothing short of the picture of health during that time, your oldest medical records dating back over a thousand years show the same thing. There is nothing that you haven't been able to handle as far as disease, not even counting the friends you have to call in favors to help you recover when you do get sick. Now, all I will need is your weight, and I'll be on my way.”
Celestia lit her horn and summoned her spring-loaded bathroom scale. She stepped onto the scale, watching the numbers spin by as they settled on… a message that was put in place of the numbers?
Lay off the cakes, sunbutt! -Nick
“You will have to excuse me, doctor. I have somepony to go deal with. Please show yourself out.”
Moments later, Celestia was holding a rather attractive earth pony above the moat in her magic. “Any last words before I drop you, Nick?”
“Wait, wait! I don't know how to swim as a pony. You can't drop me in like this, I'll drown!”
“Oh, of course. Silly me.” Celestia cast a spell, and while Nick expected to be wearing inflatable water toys to help him float, he instead found himself turned into a seapony like Twilight had done to visit the hippogriffs. “There, a temporary spell to help you out. Now, I will ask again. Any last words before I drop you, Nick?”
“I pretended to be a maintenance pony so I could sneak into your cake stash. Should help you lose weight.”
Not a second later, Nick hit the water.
