Unfortunately for the mane6, Pinkie knew her ways around the Everfree forest and knew that it had a special kind of poison joke. She hunted for 5 flowers for about an hour and came back to cook up some very special cupcakes. Her Pinkamena state of mind prevented her from making the process overly loud. Not a soul was woken up by her cooking.

The next morning Pinkie's five closest friends met in the throne room as planned. Spike was still snoozing.

They were all a bit groggy, but enjoying their small talk. Rainbow wasn't joining in and AJ eventually took note.

"So.. Dash, how'd it go the other day? Ya neva came back to tell me."

Dash sighed. "Not great."

Rarity and the others took note of this conversation after that. Rarity was the first to interject. "Dash.. What did you do?"

Dash being agitated, rolled her eyes. "Ugh, why do you automatically think that?"

Rarity retorted. "I know you. That's why."

Dash got a sting of guilt from that rebuttal. "Okay.. fair enough. I did do something not great the other day."

Rarity stammered. "Well..?"

"Okay, okay, I did something terrible! I called her a baby for acting this way! Ya happy now? Now ya know!"

There was an annoyed tone to the atmosphere and everyone but Rarity was ready to tear Dash's guts out. Rarity sensed this and quickly interjected before arguments started flying. She did her best to also be easy on Dash. "Augh, it's okay Dash. I'm sure Pinkie got over it. But just to be sure, I'll go check on her."

AJ and Twi cut in at the same time. "But we need you for the decorations."

"It's okay, it's okay. I'm sure this should take but a second Darlings."

Dash lethargically interjected. "Should I come with you?"

"Negative. I don't think she'd want to see you right now. Do not worry though Dash? We've seen worse."

Dash laughed to lighten up the mood. "Haha, yea I think you're right."

Twilight cut in this time. "Okay, well, you go do that and we'll do what we can here in the mean time."

"Sounds great Darling! See you all in a millisecond!"

The rest got to their business with a couple evil eyes at Dash at every turn. Dash had thick skin and put up with it.

About 10 or so minutes later, Rarity reached Sugar Cube corner. The bakery was in the center of Ponyville and she had to use a special route that was rarely crowded at this hour. She didn't want to rudely cut anypony off from talking to her.

Once she reached the bakery, she politely knocked and less than a minute later somepony answered. Surprisingly, it was Pinkie. Rarity had forgot that this was a Sunday and the store was slow to open.

Pinkie was still in her Pinkamena phase, but forced an obviously fake smile. "Ahh, Rarity, come in. Come in. I'm sorry about how I've been acting."

Rarity acted like the cover up worked in hopes of interjecting something important in later. "Oh, thank you Darling! There's no reason to apologize. If anything, Dash should be the one apologizing."

Rarity then walked into the bakery. There was an erie atmosphere that Rarity couldn't quite nail down.

Pinkie kept up the act. "Oh not at all! I got over it. I was in the wrong and so I decided to make you all an apology cupcake."

"You didn't have to do that Dar-"

Rarity cut herself off upon seeing the cupcakes. They each were decorated to their liking and Rarity's cupcake had simply divine decorations on it, all surrounding a diamond in the center.

"I-is that gem one fo-for me?"

"You know it silly!" In the back of Pinkie's mind, she was ecstatic. Rarity was so easy to wow. "Do you want to eat it now silly willy?"

Rarity was taken aback. She wasn't expecting this. "Well I.. I really shouldn't. Too much sugar in the morning does terribly for my facial expression, but.. what the heck. As they say, when in Canterlot!"

Rarity then levitated the cupcake near her face, taking one last look, before she swallowed it whole.

Once she finished the cupcake, she exclaimed "It tasted almost as divine as it looked. You simply MUST give me the recipe when you have a moment."

"Of course Rarity." Pinkie was filled with sadistic joy inside. Annny moment now and Rarity would regress to a 6 month old foal.

There it was! Seconds after Pinkie's response, Rarity felt a pain in her stomach and as she clenched at it, trying to cover up her pain, her body shrank at light speed. Before a minute passed, she had shrunk to the ripe old age of 6 months. Much of her memories receded to the subconscious of her mind. The only memories she retained were that those who were her friend were indeed friends. Other than that, new false memories entered her mind, a memory that Pinkie was also one of her babysitters and that the re-maneing mane6 and the cake Twins were her frequent playmates.

After the transformation was complete, the baby Rarity shivered with a faint tear in her eye.

Seeing her friend so adorably vulnerable caused Pinkie to enter this weird in between phase between normal Pinkie and Pinkamena. She looked happy, her hair was puffy again, but in the back of her mind her nefarious plan was still in the works.

She quickly comforted the new baby in front of her though, picking her up from the adult chair. "There there, babysitter Pinkie is here!"

This immediately cheered up Rarity, causing her to huge the pink pony. "Hehe! Pinkie!"

Pinkie nuzzled the baby unicorn and then warmly said. "Looks like somepony needs their diap-y changed!"

Rarity giggled some more at Pinkie as the elder pony took out the baby supplies she put in one of the cooking cabinets. The pink adult laid her friend on the table and gave a fast diaper change, causing Rarity to coo. Afterwards, Pinkie nuzzled her some more and plucked a pacifier in her mouth. The baby unicorn dozed off after this, allowing Pinkie to in two trips take her, the baby supplies, and the cupcakes up to her room.

Once the downstairs had no traces of her presence, Pinkie tucked Rarity in her bed and set up her next trap.
