"Luna, you are the best."
The midnight blue alicorn chuckled as she watched her human friend wrap himself in what could only be described as a large set of drapes. "Yes, we are aware that we are, as thou say, the ultimate princess."
"Nah, the Ultimate princess is… oh, Nevermind. You wouldn't get the reference. Anyway, I think I finally got this thing to stay on. Why is it so bulky?" He shuffled around inside the cocoon of fabric, only a small opening revealing his eyes. "I thought invisibility cloaks were supposed to be less… obstructive."
"What did thou expect, to look cool and run around in a sauve costume? Take what thou can get, Nicholas. We may be a master at illusion magic, but even the best spells only go so far. It will, at least, be effective. Function over form, as they say. Regardless, hold still." Nick did as he was told as Luna weaved her magical energies into the fabric. It started to fade, becoming almost transparent with no sign of the human underneath, and within a minute all that was visible to Nick in the mirror he was staring at was the small opening he was peeking out of.
"Incredible," Nick breathed. "Your magic never ceases to amaze me. Alright, you wait here, and I'll go snag as much cake as I can from Celly. This is gonna be great!"
"Oh, it certainly will be great, my little phantom thief …" Luna watched as the door to her room opened, the cloaked Nick stepped through, and shut it behind him. "...great for us, that is."
True to Luna's word, Nick found no trouble in slipping past the guards. The only issue, as he was quick to discover, was that he kept tripping over the fabric as he walked. A few slips and spills along the way left quite the mess behind him. Many a guard that day was confused by the many mysteriously shattering vases and tapestries pulled down by no force at all. But still, Nick persevered, and before long he had shuffled his way through the kitchens and to the door of the cake storage. And from the sounds of someone gorging themselves on cake coming from the other side of the door, it was safe to assume that Celestia was on the other side.
Inside the room, Celestia was indeed sitting, enjoying her tenth cake of the morning. Why ten? She was trying to cut back, usually it was twenty. Still, she made sure to savor every bite of the sugary dessert… until the door swung open. Usually only her most trusted guards were allowed to bother her during her cake time, but this time a mass of cloth shuffled in, any illusion it had dispelled from the antimagic charms placed all over the cake storage.
Quickly putting two and two together, she continued to nonchalantly stuff her face with cake as the pile of fabric moved by, and Nick's arm reached out and grabbed a handful of one of the many deserts before retreating back into the cloth. As Nick moved to the next cake, though, Celestia pressed her hoof to Nick's disguise, forcing it off of him as he took another step with a forceful pull.
"Going somewhere, Nick?"
Nick's eyes widened. "Celly! I was just… uh… um… how did you even see me? Luna must have-"
"This room has enchantments that could break a changeling's illusions, Nick," Celestia scoffed. "Anything Luna told you was just a trick to get you in here. Now then, I believe you were heading to the moat?"
Nick thought for a moment. "Actually, I have a better idea…"
Luna woke groggily from her sleep, stretching out her legs and yawning. She had a very restful sleep, and was looking forward to a nice, long day of relaxing since she had taken a day off to attend a concert later. Her bed belt a little wobbly, though, she'd need to fix that later-
"Morning Luna!"
"Good morning, Luna. I hope you slept well?"
Luna's eyes shot open. Nick and Celestia were sitting on the side of her bed, which was currently floating in the middle of the moat. She didn't even have time to react as the pair shoved her off the bed and into the water below.
"Hahaha! She never saw that one coming! Take that, Luna! Nopony tricks the great Nicholas AbernaaaaAAA-" Nick didn't get to finish his declaration as he too was shoved into the chilly water by a gold-covered hoof. Celestia giggled.
"Don't take my cake, Nick."
