On this post, Twilight Sparkle has realised that these deer are none other than her friends. She founds out because she didn't find any of her friends in each of their homes.
After noticing the familiar presence, she started to turn back the rubbery deer of the 5 mane back to normal, they can talk now! But unfortunately they were stuck in this squeaky deer look till Christmas.
Pinkie, RD, and Rarity seems to enjoyed their state. Fluttershy feels relief after being puffed up to normal again, Applejack is relieved to be back as well, but really disliking her current state right now. :v
Well, at least that's it. Or is it?
Since Christmas is coming, i think ima draw these from Redflare500's post from 2017 :v
