Sunset, unable to move herself out of the dimensional portal back home, pulled her cellphone out of her shirt and dialled a number.
Sunset: Uh, Applejack? Can you come to the school, please? And bring the truck.
Applejack: Why? Is somethin’ wrong?
Sunset: Well, you see, I can’t seem to fit through the portal on my own. I’m stuck.
Applejack: Wait, I know you’re still gainin’ a whole lot, but is the portal still big enough for ya.
Sunset: Well, it’s not quite that wide enough for me anymore. D’you remember a few years ago when Princess Twilight was in the same situation when she gained weight?
Applejack: Oh yeah. That big purple belly had a hard time getting through.
Sunset: Well, Pinkie and Twilight had to do the same thing to me last Friday. Besides, the portal mirror in Equestria is much smaller than the portal statue. So, it’s really my pony rear that’s the problem.
Applejack: Well, maybe if you started cutting down on all this fatty food, you might have had a better chance at-

Meanwhile, on the Equestria side of Sunset’s predicament, Sunset’s belly and rear end were far too big for just Twilight and Starlight to push. So, Twilight had called Yona, one of her students at the recently approved School of Friendship, for assistance.
Twilight: Come on Yona, she’s almost starting to budge. Give it a little more power.
Yona: Hhhnnnngg! Yona trying, but- ooooohhh! Sunset pony way too fat for mirror. Even Yona could have better chance fitting through.
And I thought she was already big in Neon’s original pics
