"Oh, my little phoenix," Celestia giggles as she is tickling her phoenix, "You were so naughty when you pranked our soft pegasus yesterday." The phoenix continues to laugh due to Celestia's tickle. Celestia stops as she stands up, "Anyway, let's wake my sister up."
Celestia is walking to Luna's room as she wants to know what will be in the poison joke effect. When she just comes into the room. The alicorn doesn't see her sister anywhere, not even in the bed. Celestia decides to check the bed and sees a dark blue bird sleeping on her bed. Giggling, she knows that it is Luna in the nightingale.
Celestia steps away from the bed, "Luna, where are you? I don't want to play hide and seek today.
Luna wakes up and chirps. When she hears the chirp, the princess of the night is surprised as she looks around her body. It's the bird wings. Luna decides to fly to the mirror and sees that now she is a nightingale. She flies to Celestia's head and pokes her, with her beak. Celestia sees that and giggles.
"Oh hello, little fella," Celestia takes the bird to her hoof, "What a beautiful bird you are! You are Luna's pet right?"
"Chirp chirp (Help me, sister)" Luna tries to flies around her sister, "Chirp (I am a bird now)"
"I don't know what you are saying but... " Celestia rubs her hoof, "Looks like my sister wants a day off." Then she looks at the bird, "Well, she should take her pet"
Luna is trying to say, "Chirp chirp (No, I am not my pet)"
Celestia doesn't know what she is saying so she just ignores it and takes the bird by her levitation, which makes Luna confused. "You know that you should go to Fluttershy cottage to let her take care of you. I will teleport there." Then she teleports her to the cottage as Celestia smiles and walks out of the room.
Luna looks around and sees that this is a treehouse, not a cottage. Applebloom, Sweetie Belle, and Scootaloo are coming back to the treehouse after trying the sewing clothes. It ends up when they messed up Rarity's clothes and Rarity was angry so they had to run away from her house. The fillies are sitting on the floor while Luna watches them from the clock.
"Aww..." Applebloom whines, "I don't know your sister is very strict about clothes."
"She is," Sweetie Belle, "I am feeling bad about that orange pony. She is posing for my sister in over two hours from now."
Spike climbs to the treehouse and gives them the book, "Here is the book that you ask for us."
"Thanks, Spike," Scootaloo waves her hoofs, "We appreciate that."
Spike looks at them, "Just don't give up. You will find your special talent in the future," Then the dragon is going to left but he sees the bird is on the clock, "Eh... Did you try to get a "take caring animals" Cutie mark?"
"No," Applebloom shakes her head, "I try to take care of my dog, Wiona, on my farm but she is not listening to me."
"I see," Spike points at Luna, who is currently standing on the clock, "Then why did I see a nightingale here." That sentence makes Luna grasp.
"I don't know," Sweetie Belle shakes her head, "I hope that it not causing some trouble,"
"Well," Spike takes a ladder near the treehouse, "I will take it to Fluttershy."
Spike puts the ladder near the clock. Luna is trying to fly away but Spike manages to catch her quickly. Luna is trying to get away from his grip but to no avail. Spike looks at the bird as he feels its color is so weird, looks like Luna's color but he decides to go down the treehouse.
"Chirp Chirp (get off me)", The nightingale is struggling to get away.
Spike sees that and he says, "Don't struggle. I will not hurt you, trust me." Luna hears that and she decides to give up struggling. Spike puts the bird on his head and heads to Fluttershy's cottage.
Spike comes to the cottage and knocks on the door. He is waiting for a while but sees no answer, so he decides to knock again. Rainbow Dash flies over the cottage and sees that Spike is knocking on the door. The cyan pegasus flies near the purple dragon and says, "Hey, Spike. Fluttershy is not going home."
"Oh," Spike rubs his head, "I see. I didn't know where I put this bird here."
"Well," Rainbow Dash suggests, "How about you take it to your library for a while?"
"Sounds like a good idea," Spike walks out of the cottage,"Thanks Rainbow."
"No problem," and Rainbow Dash flies away.
Spike heads to the library and sees something is not right. He decides to open the door carefully and sees that many fireballs are flying around while Sunset, in pony form, is fixing the light while Twilight is trying to read the book as she is slapping her book in her face. Luna feels so amazed when Sunset's horn is not glowing but she manages to controls these fireballs
"I can't believe that you used the bear's paw to scratch out the light." Sunset complains, "Now I have to fix the light with my pony form. Nice play, Twilight."
"Hey," Twilight glares at Sunset, "I will control it better."
"I hope you can in the future," Sunset takes a bag of bits from Twilight, makes the purple unicorn grasp as she tries to take it back but Sunset pushes her out, "This money for the light."
"But you can create them by forming a crystal, right," Twilight retorts. "So... can I have the money back?"
"No," Sunset shakes her head, "Even creating crystals to produce light requires the material."
"Fine," Twilight lies on the sofa and turns to the door. She sees the purple dragon standing there with the nightingale on his head, "Oh hi Spike, where did you get that bird?"
Spike walks to the sofa and sits next to Twilight, "Oh, this one I found in cutie mark crusader's treehouse. I admit that this bird has the unfamiliar color."
Twilight gets up and watches the bird, making Luna confused. Twilight levitates Luna and watches her closely, "I have to admit that this bird has Princess Luna's color." Then Twilight rubs her chin, "Is this bird really Princess Luna?"
"Nah," Spike waves her claw to reject, "How can't this bird be Princess Luna? Poison Joke?"
"It can happen, Spike." Twilight retorts, "Remember when a cat is really Princess Celestia?"
"I don't believe that," Spike takes out the magazine and sees Fluttershy is on the first page in the fashion magazine, "What? Fluttershy is famous?"
"WHAT?" Twilight takes the magazine from Spike's claw as she looks at the magazine, "How?"
"I don't know," Twilight stands up, "Let's go, Spike, Rarity will maybe be jealous of her."
"I'm on it."
Twilight and Spike open the door and go out of the room. Luna is flying to Sunset's head and pokes her forehead with her beak, but Sunset really focuses on fixing the light, making Luna angry. She decides to poke at her eyes, making the orange unicorn fall from the ladder.
"Ouch" Sunset grabs the bird by her hoof, "Hey, you are so annoying here. Can you wait for me? I am fixing the light here." The bird shakes her head as Sunset glares at it. She forms the ice cage and throws Luna into it. Luna looks around and sees the unicorn is locking the cage. Luna tries to get out of the cage while Sunset turns back to fix the light.
After two hours, the light is fixed as Sunset looks at her doing. Luna is sleeping while standing in the cage. Sunset takes the bird carefully while looking at it, this nightingale for her is having a strange color. It looks like Luna's color. Sunset wakes Luna up as the princess of the night grasps and opens her eyes. Looking around, she is currently on Sunset's head.
Sunset looks at the nightingale, "You really are a strange bird. Being a nightingale but you really don't know how to sing."
"Chirp chirp (Because I'm not a nightingale)" Luna tries to talk to the orange unicorn, "Chirp (Help me!)
"You know that I can't understand what you say right?" Sunset puts the bird on her head, "Let's head to the blacksmith. I hope that I can learn how to make a guard." Luna huffs as she has to accept it.
Sunset goes to the blacksmith and sees Lemon Heart is putting the sword in the display and puts the price 150 bits. The orange unicorn is feeling weird while Coral Blade is carrying many rusty things in the store. Lemon Heart sees Sunset and walks close to the mare.
"Hello, lady ~," Lemon says in a romantic voice, "How can I help you?"
Coral facehoofs as Sunset decides to play along, "Oh, nothing. I came here to learn about blacksmithing."
"A beautiful lady like you shouldn't handle dirty," Lemon suggests, "Let the heavy thing to the stallion."
"You know, Lemon," Sunset puts a pan on Lemon's head, making the old pony confused, "That is the worst courting I ever heard, I don't know how you can have your wife." Sunset's sentence makes Lemon embarrassed while Coral laughs out loud.
"How can you know my name?" Lemon asks, "I never met you before. Don't tell me that you are that orange dragon."
"Nice guess, Lemon," Sunset points her hoof at herself, "It's me, Sunset Shimmer."
Lemon is shocked when he hears that while Coral Blade laughs, even more, it feels like a comedy show for her. Lemon glares at the laughing captain, "not funny, Coral. You two plan this?"
"No" Coral manages to say, "but I feel funny like that. You should look at your face at that time." Lemon huffs and goes inside while Coral looks at Sunset in pony form as she feels quite jealous when the orange unicorn is quite cute. Looking up, she sees the weird bird on her head and catches the bird. Luna's eyes widen as the captain looks at the bird, "Wow, this bird is beautiful. It looks like Princess Luna so much."
"I doubt that she is." Sunset rolls her eyes, "Because I didn't see any bird have this color"
"I see," Coral looks at the unicorn and teases, "But look at you. Now you are a pony so you can't walk by two legs or back hoof things, and you don't look scary anymore."
"Actually," Sunset stands on two back hooves, make the captain surprise, "I can walk by two back hooves without a problem."
"Really?" Coral pokes the hooves, "How can you do that? No pony can do that before."
"Except me, long story," Sunset starts walking inside, "Now I have a lesson to learn to craft a sword for me."
The night has come. Sunset and the purple duo are going back to the library. The famous thing is harder to solve than they thought so they leave there for tomorrow. Sunset is making the herb tea because she wants to check if this bird is actually Princess Luna or not. When Luna drinks the tea, she returns to normal form immediately, which makes everyone inside surprised, except Sunset.
"Woo hoo," Luna stretches her body, "It's good to be back to normal."
"Welcome back, Luna," The orange unicorn drinks the water, "Not like me, I have to keep this form until the gala."
"I see." Luna waves her hoof, "Honestly, I am surprised when you manage to walk by two back hooves."
"Well, not only me." Sunset leans on the sofa, "I hope that you are at the gala."
"So," Spike walks to Luna, "Why are you becoming a bird, or nightingale in particular."
"I doubt that this is my sister's prank," Luna huffs, "I have to pay back to her. Now, I have to go. See you again at the gala."
Luna stretches her wings to fly to Cancerlot while the trio doesn't know what to say. Sunset takes the magazine and finds that Fluttershy is on the first page of the magazine. She hopes that the yellow pegasus will be fine for that. The Gala is closing and Sunset knows that she will have to deal with the Sisters.
