SunPie Sink And Stink

Coming back from the orchard one morning, Applejack hears two familiar voices calling for help in the distance.
Following them leads her to the Sweet Apple Acres manure pit, and a surprising sight…

Applejack: Heavens to Betsy! What're y'all sugarcubes doing in my manure pit?
Sunset Shimmer: It's… A long story. Could you just get us out? We've been stuck here all night!
A-and we're slowly sinking deeper!
Pinkie Pie: And it's reeeeally smelly! P-U! I don't wanna be a Stinky Pinkie! Please help us!
Applejack: Chuckle! Aw, my cute little piggies, hold tight! I'm gonna go get some rope… And the camera!
Chuckle! Try not to go under 'til I'm back, m'kay?
