My Little Pony: Changelings

Pinkie Pie hasn't been in Ponyville all day, and Twilight Sparkle is worried, so she takes her friends to Pinkie's candy house.

"Has Arima heard any news about Pinkie since yesterday?"

"I really don't know why I came to see her so early. The Princess of the Universe hasn't even raised the sun yet."

Just as Rainbow Dash complained, Pinkie Pie ran out of the room and hugged all the ponies inside.

"Thank goodness you're all here. Now there's no time to waste."

Qunxing Huanghuang looked at the stone candies piled up in the room, picked up one and ate it.

“It’s a little hard, but it tastes pretty good.”

Pinkie took out the mixed candies and said to them.

"My sister Huiqi is coming to visit me soon, and you have to help me taste the candies I made."

Looking at the candies that filled the room, the ponies couldn't help but breathe a sigh of relief. This was going to be a daunting task.

As the candy-eating frenzy came to an end, Starry decided not to eat candy anymore, and Pinkie came over pushing a cart.

"Who of you wants some more candy?"

"No."

"I think that's enough."

After hearing this, Pinkie Pie started to worry about her choice, and then she poured candy into her mouth frantically. Seeing Pinkie Pie like this, Twilight Sparkle walked over to comfort her.

"Gray is your sister, I think she would like your candy, and you've made enough, and she's only in Ponyville for a week."

"This isn't just for Huiqi, I'm doing this for everyone."

After picking out the candies from the pile, Qunxing Huanghuang said to them.

"If this continues we'll all have cavities."

Then Pinkie Pie began to explain that she wanted to make a rock candy necklace. After the ponies heard this, Rarity began to worry about how to pick up Gray Pie at the train station. When Pinkie Pie heard this, she yelled and quickly ran out.

The picnic by the lake was quickly arranged by the ponies, and Starry Night sat on the ground, waiting for Gray Pie to come with other ponies. Then, in Pinkie's expectation, Gray Pie finally came over. Twilight Sparkle walked up and began to introduce.

"I'm glad you came to Ponyville to stay with us before you leave home. Pinkie Pie told us a lot about you. I'm Twilight Sparkle, and this is Applejack, Fluttershy, Rainbow Dash, Rarity, and Star-Spangled Glitter."

Qunxing Huanghuang walked forward and said to Huiqi.

"Long time no see, Miss Huiqi."

"Long time no see, you... dyed your hair, your white hair looks beautiful."

Hearing this, the ponies were shocked, and Pinkie Pie jumped up excitedly.

"Oh my god, I can't believe you guys know each other."

Twilight Sparkle also came over and said.

"How did you two know each other?"

Before Qunxing Huanghuang could reply, Huiqi spoke.

"I was talking to a lavender pony earlier when he came to me to ask a question."

"Oh, that's a coincidence. What did they ask?"

"About plunder..."

Qunxing Huanghuang quickly covered Huiqi's mouth, and then said to Twilight Sparkle.

"Okay, okay, that's it. Let's talk about something else."

Twilight Sparkle looks confused, and then Rarity comes up and introduces herself. After a game of hide-and-seek with rocks, the game ends with Starlight finding a pebble in Gray's pocket.

Inside the mine, Qunxing Huanghuang brought Huiqi into a huge cave. After prying open the granite that was blocking the view, a huge gem cave appeared before their eyes. When Biqi saw Huiqi's expression, she started laughing.

"Wow~ Stars are shining, I didn't know you knew so much about stones. This place is so beautiful. Huiqi looks so happy."

The Lightning Pegasus Exam

As the stars walked down the street, they saw ponies gathered together next to the Curio Shop, arguing over the different uniforms they were wearing. When they walked over, they found Rainbow Dash trapped in the middle, unable to move.

"Did something happen?"

"It's Rainbow Dash. She knows nothing about the history of the Wonderbolts. We are trying to get her to learn it."

When Qunxing Huanghuang heard this, he immediately became interested and said to them.

“I have a great idea!”

After a long time...

"This is a terrible idea. Has any of you seen Pinkie Pie?"

"I don't know. Applejack and Fluttershy are missing too."

"Oh no! It's the Easy Gliding Commander! Everyone, take cover!"

A Pegasus led the other Pegasus and flew over their heads. Finally, Starry Night found all the ponies and returned to their original time and space. After putting away the backup time and space scroll, Starry Night was left with no other options. Finally, Twilight Sparkle used Rainbow Dash's learning ability to successfully pass the exam.

(I originally wrote a lot, but it ran out, so I'll just write the general idea.)
