Narrator: Pinkie Pie is a little pink pony who works in Ponvyille. She is friends with almost every pony in the town. She's friends with Flash Sentry and Derpy up at the castle.
Pinkie Pie: Hello, Derpy. Hi, Flash.
Derpy: Bonjour, Pinkie.
Flash Sentry: Hello.
Narrator: She is also friends with Soarin and Dr. Hooves on the Little Pony line.
Dr. Hooves: Morning, Pinkie Pie.
Pinkie Pie: Good morning, Dr. Hooves. Hello, Soarin.
Soarin: Hello, Pinkie.
Narrator: Pinkie Pie is even friends with other ponies in Ponyville, like Twilight Sparkle at Ponyville Quarry and Cheese Sandwich at Ponyville Docks. But her best friend of all is Spike the Dragon.
Pinkie Pie: Hello, Spike.
Spike: Hello, Pinkie Pie.
Narrator: Spike has been Pinkie's best friend since the time she helped him when Spike got stuck in a landslide near High Farm. And the two of them always try to help each other whenever they can. One day, Hoity Toity came to see Pinkie Pie.
Hoity Toity: Pinkie Pie, I have an important job for you.
Pinkie Pie: What is it, sir?
Hoity Toity: A new unicorn is coming here in my town on trial. I'd like you to show her around and work with her for a few days.
Pinkie Pie: What's the new unicorn's name, sir?
Hoity Toity: Her name is Starlight Glimmer. She's not the easiest unicorn to get along with, Pinkie. So please make her feel welcome. She should be here in another five minutes.
Pinkie Pie: Thank you, sir. I'll be very nice to her.
Narrator: Hoity Toity left. And about five minutes later, Pinkie heard an unfamiliar horn.
Pinkie Pie: That must be Starlight.
Narrator: Sure enough, an unfamiliar unicorn was coming into the yard. She stopped nearby Pinkie.
Pinkie Pie: Hello. I'm Pinkie Pie. You must be Starlight Glimmer. Hoity Toity told me that I was work with you.
Starlight Glimmer: You mean I have to work with a pony who wears a bad color?
Pinkie Pie: Excuse me?
Starlight Glimmer: That pink color looks terrible on you. How can your leader even look at you? And why do they even call you 'Pinkie Pie'? A better name for you would be 'Crazy Pony'.
Pinkie Pie: My leader, Hoity Toity cares for all of his animals, no matter what color they are!
Starlight Glimmer: Oh, really?
Pinkie Pie: We have to get to work now. We have some trucks to deliver to Sugar Cube Corner, and then we have to deliver more to the train station.
Starlight Glimmer: Well, Crazy Pony, if I'm to work with you, you go at the back of the line. I don't want to look at your pink fur.
Narrator: Pinkie Pie felt proud to wear pink, and she wanted to tell Starlight that she was being rude. But she had told Hoity Toity that she would be very nice to Starlight. So she said nothing. On the way to Sugar Cube Corner, Pinkie and Starlight passed through the town hall. Hoity Toity was there.
Hoity Toity: Ah, Starlight Glimmer, I see you're now working with Pinkie Pie. Are you two getting along alright?
Starlight Glimmer: Oh, yes, sir. Pinkie let me go in front so I could look around the town.
Hoity Toity: That's great. Carry on.
Narrator: Pinkie couldn't believe it. Starlight Glimmer had lied to Hoity Toity.
Pinkie Pie: How dare you lie to Hoity Toity!
Starlight Glimmer: If you tell him, I'll push you right into the sea! Don't say a word. Got that, Crazy Pony?
Pinkie Pie: Um, yes, Starlight.
Narrator: Pinkie said nothing all the way to Sugar Cube Corner. And she didn't say anything all the way to the train station either. She was too afraid to say anything to Starlight Glimmer.
Starlight Glimmer: Honestly, I don't know why your leader has more earth ponies than unicorns. Magical creatures are better and more cleaner than you dirty earth ponies.
Discord: That's what I say too. Magical creatures are new and revolutionary. Earth ponies are only second best.
Starlight Glimmer: Who are you?
Discord: I'm Discord. I was the first creature to arrive in this town.
Starlight Glimmer: My name's Starlight Glimmer.
Discord: Well, Starlight, how would you like to spend the night at the creatureworks with me and the other creatures? We'd be happy to have a new magical creature there.
Starlight Glimmer: I'd like that. I'll be there soon.
Starlight Glimmer: Crazy Pony, if don't get rid of that pink fur by tomorrow morning, I'm going to push you into the sea!
(Starlight Glimmer leaves)
Pinkie Pie: (sighs)
Narrator: Pinkie Pie had never felt so sad before. She puffed slowly home.
Spike: Shining Armor, does Pinkie Pie seem sad to you?
Shining Armor: She must have had a bad day or something. Why don't you go talk to her, Spike?
Spike: All right. (Walks over to Pinkie Pie) Pinkie Pie, is everything okay?
Narrator: Pinkie Pie looked up at her friend, Spike. She wasn't sure if she could tell another animal about her problem with Starlight. But on the other hoof, Spike had stood up for Pinkie before. So maybe he could help her.
Pinkie Pie: I've been having bully troubles with this new unicorn named Starlight Glimmer. She insulted my name and color, and she said that if I don't get rid of it, she'll push me into the sea.
Spike: I've had bully troubles before too, Pinkie. But most of those times, I just stood up to them, and that's what you should do to Starlight.
Pinkie Pie: I don't know, Spike. She did sounded serious when she said she'd push me into the sea.
Spike: Bullies always try to scare others like that. You just need to be stand up to her and tell her that you've had enough of her rudeness.
Pinkie Pie: Well, okay, I'll try it. Thanks, Spike.
Spike: You're welcome.
Narrator: So the next morning, Pinkie Pie waited for Starlight Glimmer to arrive at the yards. Before long, she heard Starlight's horn, and the light grayish heliotrope unicorn came into the yard.
Starlight Glimmer: Hey, Crazy Pony, you are here?
Pinkie Pie: It's Pinkie Pie! Not Crazy Pony!
(Starlight Glimmer comes towards Pinkie Pie)
Starlight Glimmer: So you are here. And you still have your pink fur. Come with me now!
Pinkie Pie: No!
Starlight Glimmer: I said I was going to push you into the sea if you didn't get rid of that pink coat. Now come!
Pinkie Pie: No! You leave me alone! I've had it with your rudeness! If you don't stop bullying me, I'll push you off the path!
Starlight Glimmer: What? No!
(Starlight Glimmer reverses into a siding and breaks the buffers)
Starlight Glimmer: Now look what you made me do! I'll tell your leader you pushed me into this siding, and he'll never know about me bullying you and that I lied to him yesterday about us.
Hoity Toity: (Clears throat)
Starlight Glimmer: Uh, hello, sir. I was just telling Pinkie that she needs to be more careful with other animals and...
Hoity Toity: Starlight Glimmer, you're already in a lot of trouble. Don't make it worse by telling more lies to me.
Starlight Glimmer: Oh, but, sir. I...
Hoity Toity: Starlight, I heard every word you said, and I'm very disappointed in your behavior. You've been a bully to Pinkie, and you lied to me yesterday. I want you out of my town immediately. I will not have dishonest ponies and bullies in my town.
Starlight Glimmer: Yes, sir.
(Starlight Glimmer leaves)
Hoity Toity: Pinkie Pie, you were very brave to stand up to Starlight like that. I'm proud of you.
Pinkie Pie: Thank you, sir.
Narrator: Pinkie was glad that Starlight was gone, but she's even more glad to have a friend like Spike.
Pinkie Pie: Thanks for your advice again, Spike. You're a very good friend indeed.
Spike: No problem. I'm always happy to help out a friend whose having bully troubles.
