It was the day after Starlight had been pulled free out of the school portal. She and Rainbow Dash were at the mall’s clothes store. If Starlight were to stay in the human world for a couple of months, she was going to need the right sized fitness wear for it.
 
Starlight was undressing herself ready for Rainbow to bring her her jogging clothes, when suddenly the dressing room curtain flung open.
 
Trixie: Oh. Heh. My apologies. Trixie thought this one was empty.
 
Starlight raised an eyebrow, which read both confusion and annoyance.
 
Trixie: Wait, I know you. You’re Starlight, aren’t you? The one who spent nearly a mouth stuck in a statue?
 
Starlight: (sigh) The very same. I don’t do autographs.
 
Trixie: (Snickers) I’m impressed. How did you manage to gain all of this? (Rubs Starlight’s tummy)
 
Starlight: A lot of ice cream. And I mean, A LOT of ice cream.
 
Trixie: Hmm. Fascinating. But, if you think you’ve had it bad, you haven’t even seen Trixie’s- oh, uhhh… ‘s good friend, uhh, Pinkie Pie. Yeah, she’s much bigger than you and eats like 100 pounds of candy a day. In fact, all she ever thinks about is candy.
 
Starlight: Really?
 
Trixie: Yeah. From what I’ve seen, Pinkie Pie, Applejack, Rarity, Sunset Shimmer, even Twilight Sparkle have eating addictions. They all have huge bellies cause they just love eating.
 
Rainbow: Ahem?
 
Trixie turns around and sees Rainbow standing next to her.
 
Rainbow: Actually, Twilight and Sunset don’t like being overweight and they’re trying hard to lose their pudges.
 
Trixie: Rrrright.
 
Rainbow: Can you leave her in privacy now?
 
Trixie: Alright, fine. I’m going. (Leaves)
 
Starlight: Hmm. She didn’t seem too bad.
 
Rainbow: Trust me, you have no idea. Now slip these on! Hup to it!
 
She hands over some XXXXL jogging tops and bottoms.
 
Starlight: Uhhhggg.
