The way Bedtime and Bedtime Story goes in Yuna and Dusty.
Back at Canterlot.
Princess Luna: Did you have fun today, Yuna?
Princess Yuna: Yes, Mama.
Princess Luna: It's bedtime, Yuna.
Princess Yuna: I'm all set for bed, Mama.
In Yuna's bedroom.
Princess Yuna: What bedtime story are you gonna tell me?
Princess Luna: I got one.
Princess Yuna: Please tell me, Mama!
Princess Luna: Alright. It all started, one thousand years ago...
In Princess Luna's story.
Princess Luna: (narrating the story) Your Aunt Celestia and I got the Elements of Harmony to defeat Discord when he was evil.
Discord: Oh, this is so much fun. How about a game of 'Pin the Tail on the Pony'?
Princess Celestia: (gasps) Playtime is over for you, Discord!
Discord: Oh, I doubt that. (munching) Hungry? Suit yourselves. Oh! What have you got there?
Princess Luna: (narrating the story) Then we got out the Elements of Harmony to defeat him.
Princess Celestia: The Elements of Harmony!
Princess Luna: With them, we shall defeat you.
Discord: (laughing) You should see yourselves right now. The expressions on your face. So intense. So sure of yourselves.
Princess Luna: (narrating the story) So, We turned him to stone.
Discord: (laughing) Hilarious!
Princess Luna: (narrating the story) The plunder seeds sinked under the ground.
Princess Yuna: You mean under your hooves?
Princess Luna: (narrating the story) Yes. It steals the magic from the Tree of Harmony and captured me and your Aunt.
Later in the story, the Princesses transfer the magic to Twilight.
Princess Luna: (narrating the story) Your Aunt Celestia, Cousin Cadance and I have no other choice but to transfer our Alicorn magic to Princess Twilight Sparkle.
Princess Celestia: We must begin at once.
Princess Luna: (narrating the story) And so it is done, So she can keep it away from Tirek.
Tirek: What have you done?
Princess Luna: (narrating the story) Tirek forced us to talk, But We refuse to corporate.
Tirek: Getting rid of your magic so that I cannot take it from you? That was your plan? How does it feel, knowing that soon, every Pegasus, Unicorn and Earth pony will bow to my will, and that there is nothing you can do to stop it?
Princess Celestia: You will not prevail, Tirek.
Tirek: Give my regards to Cerberus.
Princess Luna: (narrating the story) He banished us to Tartarus.
The story ends.
Princess Luna: And then, Twilight and her friends defeated Tirek and ruled their own kingdom.
Princess Yuna: Wow! Great story, Mama.
Princess Luna: Thanks, Yuna.
Princess Yuna: Do you think I'd be a great Princess like you someday?
Princess Luna: I'm sure you will one day (kissing Yuna) Goodnight, Yuna.
Princess Yuna: (yawns) Goodnight, Mama.
Princess Luna: Happy dreams, My daughter.
Princess Yuna: (thinking and sleeping) Hmmm. Maybe I can go on the adventure of my own.
