I haven’t come across this yet myself, but with the weird superpower i have, i usually find it not long after asking for help finding it in half the cases…
But anyway!
Im pretty sure that there were at least two parts to this, and they were found here on the site (though maybe somewhere on Reddit too).
It’s about a mail order fluffy business, and the 'main character’s is a worker that packs up the fluffies to be sent out.
You could have the fluffies shaved, ants put into the box, scary noises, other abuse type things (Im sure there’s hugbox stuff, but i cant remember them).
I think one fluffy (possibly an expensive one?) Was supposed to be delivered by drone, and it didn’t end very well for the fluffy (i dont think it made it to its destination)
This does makes a bell ring for me; a feral foal was taken in by a mill and start a hell of a lot of chaos, like teaching the fluffies there sorry poopies.
