Today was the celebration in Ponyville for Celestia’s return to good health. Three weeks ago she had been pranked by Dash and Pinkie with poisonous joke, and was not seen for days. Only three ponies knew the truth of what had happened to her.

Twilight and even Luna believed Celestia’s story that she had caught a contagious illness and quarantined herself for their own safety. The truth of the matter was that the poisonous joke had turned Celestia into a large, tasty wedding cake. Luna had devoured the entire cake upon coming to see why Celestia had not woken up that morning.

It did not end well.

Now, everypony was gathered in Ponyville to celebrate and Celestia knew just what to do to get even and teach Pinkie and Dash a lesson.

“Celestia, over here!” Twilight shouted. She waved at the princess and beckoned her to town hall. There were decorations everywhere and at least a hundred ponies that had come to celebrate.

“Twilight, my faithful student, you’ve outdone yourself,” Celestia said.

“It’s the least we could do. I was so worried when you vanished. I thought that Luna might have done something horrible to you.”

Celestia’s eye twitched as she bit her tongue. “Yes. Luckily, that is not the case.”

Twilight failed to notice anything odd. “We have a V.I.P. area and private rooms on the second floor of town hall. You and Luna can relax, away from the crowds of ponies, if you wish.”

“Thank you. Tell me, where are the other Elements?”

“They’re inside already. Were you looking for anypony in particular?”

“No.” Celestia smirked and looked down at her pupil. “Tell me, do you have your daily friendship report ready? I want to read it before the party.”

“What? You want the friendship report early? But I didn’t—I mean, I left it at home! Yes, at home. I’ll be right back and tell you all about it!” Twilight began twitching nervously and fidgeting until Celestia nodded, dismissing her. Twilight turned and ran home to make up a report.

Celestia found the two ponies she was looking for when she walked into the town hall. Pinkie was poking at the ground in the far corner, chatting with Dash. The pegasus glanced nervously at Celestia, who had threatened to banish them to the moon if they ever spoke of how she had been eaten and defecated by Luna.

“Greetings, my little ponies,” Celestia said with a smile. “How are you two today?”

“We didn’t say anything to anypony, we swear!” Pinkie blurted.

“Pinkie! Not so loud,” Dash scolded.

“Girls, I’m not upset with you. In fact, I’d like to thank you. If we could just head upstairs for a moment,” Celestia stated.

“Yes, Princess.” The two ponies followed her upstairs to the V.I.P. lounge, failing to notice Celestia lock the door behind them.

“So, uh, you’re not mad anymore then?” Dash asked.

“Nope.” Celestia’s grin slowly grew into a wide smile, stretching from ear to ear. A breeze caught her mane and the roomed seemed to darken ominously. “In fact, I’m about to feel a whole lot better about everything.”

Dash tilted her head in confusion, before looking to her left. Pinkie seemed to sense something she could not, as her mane had already gone flat. “I don’t get it.” Dash turned to face Celestia. “What’s going on?”

Luna had arrived at town hall late in the morning to celebrate with her sister. She had expected to find Pinkie stalking her as she had when Celestia had gone missing, but she was nowhere in sight. Luna almost expected her to be planning another of her annoying little surprises. Perhaps she would jump out of a potted plant and shoot confetti at her? She considered it a miracle Pinkie had stayed out of trouble this long.

When she made it to the second floor of the town hall, she found Celestia waiting for her.

“Lulu, so glad you could make it,” Celestia cooed.

“Tia, I’m glad to see you are feeling better. What is this?” Luna asked. She walked over towards a large platter of cupcakes.

“I had Pinkie whip you up some cupcakes, to say thanks for running the kingdom while I was indisposed.”

“Thank you. Will you enjoy some with me?” She glanced down at the cupcakes, finding them divided into two flavors. On the left side were cyan-frosted cupcakes with bread baked into a rainbow of colors. On the right side were strawberry cupcakes, nearly sparkling from the thick layer of pink sprinkles.

“Of cour—”

“Princess Celestia!” Mayor Mare interrupted. “We need your help, there is a fire at the Golden Oaks library!”

“Tia, we will help,” Luna offered.

“No, sister, it is okay. Enjoy your cupcakes and tend to the celebration below. I’ll go handle the situation with Twilight.” Celestia turned to the nearest window and jumped out of it, flying towards the pillar of rising smoke.

Dash could neither move nor breathe. She felt as if she had been chopped into a dozen pieces, still acutely aware of each chunk of her body placed in a small cupcake wrapper. Her fur had taken on the consistency of icing from Celestia’s spell. She could still see, but only a small area next to the cupcake that represented her eyes.

Pinkie was trapped in a similar situation next to her, and were the two capable of making noise, they’d be screaming loudly. They knew that Celestia intended to feed them to Luna for revenge, and were horrified to even imagine what that would feel like.

Dash felt the tray move, and then magic plucked a piece of her up into the air. Her world turned upside down as the bottom half of the cupcake was bitten off. She felt a warm, slippery tongue pushing against her neck—or what would have been her neck if it was not currently a confectionary treat.

Saliva mixed in with the bread, swishing it between the pony’s teeth. Two rows of teeth closed down over the icing, cutting off Dash’s vision. She felt herself smothered across the teeth as her icing melted and spread. Dash tried in vain to scream again for help, hoping anypony would save her.

There was a strong suction against her and she felt that piece of herself slide into the pony’s throat. Hot, muscular walls contracted around her, balling her up into a slick blob of cupcake batter. Slowly she slid down the throat until she landed inside the stomach with a gentle plop. Her vision was nearly useless now in the pitch black depths of the stomach. She felt her flank get bitten into, despite being separated from it by several feet.

As the pony nibbled on her flank, Dash wondered what it would be like to have her various pieces slowly eaten, digested, reassembled in the colon, and passed out of Luna. Would it leave her scarred for life? Could she still be a Wonderbolt?

Another piece of Dash landed in the stomach and she felt the pony beginning to move. The stomach began to fill with liquid and she sloshed around as it contracted. Dash realized in horror she was being digested. Already she could feel bits of herself stuck to the teeth, in the throat, and dissolving in the stomach. Would she feel herself throughout Luna’s entire body soon?

Wheeee! Pinkie thought as a rush of fruit punch washed her down a narrow throat. She had seen Dash get taken off the tray, and would soon join her. The experience had been unusual, but Pinkie knew it could no more be avoided now than breathing could when she was alive.

So Pinkie decided to enjoy it. Each bite against her and every feeling of her various body parts in cupcake form being devoured. Some were nibbled on in dainty bites, other pieces swallowed intact. It was delightful how many ways the dozens of Pinkie cakes were being eaten. She had feared at first Luna would just shove them down her throat like a fat kid in a candy store. Pinkie considered herself lucky to be digested with a little variety.

Pinkie couldn’t see or sense Dash. She felt a stomach close around her and begin kneading her. It was full of liquid, and small bits of something else, something solid. She wondered if her and Dashie would be joined by any of the real cupcakes she had baked this morning. Perhaps some hard apple cider, or Derpy’s muffins would be next. Pinkie wondered if she would be able to taste one of Bon Bon’s treats if one landed in the stomach beside her.

Her only regret was that there were a hundred ponies having a wild party, and she was stuck in a tummy. She felt cathartic as her body dissolved into a state of warmth and spread into the small intestine.

Celestia returned from the library covered in soot and ash. Behind her was a downtrodden Twilight. They proceeded straight up to the second floor of the banquet celebration where they found Luna reclining in a chair.

“Tia, you look horrible!” Luna observed.

“There was a minor misunderstanding between Twilight, a friendship report, and a Baelrog,” Celestia explained. She glared at Twilight who still refused to lift her eyes from the floor. “Next time, Twilight, please just tell me you don’t have a report ready.”

“Yes, Princess Celestia,” Twilight replied.

“You’re dismissed. Go enjoy the party and say hi to your friends.”

Once Twilight had left, Celestia did her best to hide a smile. “So, Lulu, how were the cupcakes?”

“They were delicious, Tia. Thank you.”

She barely avoided giggling as she watched Luna pat her stomach. “Well, after you ate my cake I figured a few dozen cupcakes wouldn’t fill you up.”

“You’re correct. Would you like to go down to the banquet and see if there are any more of those little carrots on a stick?” Luna asked.

“That sounds wonderful.”

A day had passed since the banquet and Luna couldn’t stand how clingy her sister seemed to be lately. Celestia had become worse than Pinkie Pie, and every time Luna turned around she’d catch her watching from a distance or giggling.

Luna pushed the thought from her head as she went to work running the night court. She had a long and uneventful session. Luna had at least hoped for some idle conversation from the guards about the meteor shower she had scheduled for Thursday.

The nearest Luna got to excitement was receiving a letter from Twilight Sparkle, asking if Dash was in Canterlot for a Wonderbolt’s air show. Twilight also asked if she had seen Pinkie, though Luna considered her absence a blessing as her uncanny abilities were very creepy. She had sent a reply stating that neither Luna nor Celestia had seen them.

By the time Luna was done watching over the night, she ate a quick breakfast and sped towards her room. Luna didn’t want her clingy sister to hunt her down and attempt to “bond” or otherwise ruin a well-deserved nap.

Fate had other plans. As Luna rounded the last corner towards her bedroom, she ran into Celestia. After making a small grunt from the collision, she took a step back. “Oh, Tia, how lovely to see you.”

“Yes, Luna. I thought you might want to go for a stroll through the gardens on the edge of town?” Celestia asked.

“Tia, I just want some sleep. I think that ratatouille the chef served had some spoiled vegetables in it, and my stomach is a little upset.” She was only partly lying, for she did feel another large bowel movement forming.

“Just a quick walk then, it may settle your stomach. Come.” Celestia beckoned her forward, clearly not wanting to take “no” for an answer. Luna followed her outside and walked through the garden towards the small glade near the castle.

“So, how was the night court?” Celestia asked.

“The same as always. Everypony is asleep, so I didn’t get many petitions,” Luna stated.

“Well, you have a meteor shower coming up. Perhaps I can set the sun early and encourage some more ponies to come enjoy your night.”

“Really? That’s awfully nice of you! I have felt a little closer to you since you got back.”

“Me too, Lulu.”

Luna’s stomach rumbled and she found herself fighting her body to hold in her bowels. “Ugh, there’s that soup I was talking about. I, uh. . . need a moment, Tia.”

“Of course.”

Celestia stopped and watched Luna sprint into the nearby glade. Her plan was working perfectly to ensure Dash and Pinkie were collected in one pile, and not the sewer system. She had been getting tired of following Luna around like this, but it was necessary to ensure she be there to cast the reversal spell, and make sure she got both ponies in one spot.

Celestia waited as she heard several loud, wet noises from the cluster of trees. Luna was not having a pleasant time in there.

Once Luna had finished her business, she exited the forest blushing slightly. “Not one of my better days,” she explained. “I fear I really must get to bed now. Thank you, Tia.”

“You’re welcome. Sweet dreams, sister.”

After Luna had left, Celestia trotted into the clearing, finding herself using magic to pinch her nose closed. Luna could weaponize the odor coming off the pile of excrement she had left in the middle of the glade.

Celestia began to explain herself to Pinkie and Dash. “I hope you two have learned your lesson about pulling pranks on royalty.”

She got within a few feet of the steaming-black pile sitting amidst the blades of grass.

“Now that you two have been through the horrors that I was put through, I think my revenge is complete. I can sleep soundly, knowing you would never dare to mention how you turned me into a cake and I got eaten. Now that you know what it is like, you can truly appreciate my benevolence at allowing you two pranksters to get off this easy.”

Celestia began to charge her horn and aimed at the feces. The fact that two ponies were current living life as that noxious filth amazed her. They were literally made entirely of it, and not only that, they were fully aware of it. They were truly helpless and completely at her whim. If she turned around right now and left they’d be stuck like that forever, knowing they were nothing but excrement. . . but that punishment was too severe, even after nearly leaving Celestia stranded that way. It was time to set things right, content they had learned their lesson.

“What do you have to say for yourselves?” She cast the spell on the pile, expecting Pinkie and Dash to emerge from it unscathed as the spell was reversed.

Nothing happened.

Celestia tilted her head and searched her mind for an explanation. She had collected poison joke, carefully crafted this spell, and made sure to perform it in a controlled environment. She had triple-checked the counter-spells and even used a squirrel to test the spell out. Needless to say, Celestia did not enjoy the taste of squirrel cake, yet it proved her spell worked.

She fired up her horn again, bathing the poop in magic. When nothing happened, she tried a third and a fourth time with no luck.

Celestia was baffled. This should have worked. This would work. “Luna…” she muttered. “She must have caught onto my prank. She’s probably getting ready to prank me again!”

She jumped into the air and flew back towards the castle. Celestia landed on her sister’s balcony and barged into the room, heading straight for the bed where Luna was softly snoring.

“Luna! Awake at once and explain yourself!” Celestia shouted.

“Wha—huh?” Luna rubbed her eyes and sat up. “Sister, what is wrong?”

“What did you do with the cupcakes I gave you?”

“At the banquet?”

“Yes!”

“Oh, I wasn’t really hungry. I put them out for the guests.”

“But you said they were tasty!”

“I told you they were tasty to be polite.”

Celestia’s jaw fell wide open. “You… didn’t eat the cupcakes?”

“No, Tia. Why?” Luna asked. “All the ponies there really enjoyed them. They said they were the tastiest cupcakes they’d ever eaten.”

“Shit.”
