Thanks to Amos the WonderHorse for this. Amos asked on Twitter:
Can I be mini pony of the day? Please? (I even asked nicely.)
Yessss. I think this is a PSAMP first, where we've had an actual mini horse requesting entrance into out archive of great mini ponies of the day. And like I'm gonna turn that down. You can find Amos at the Twitter link above, on Facebook and in this great video recapping Amos' 2012.
