Just wait until that Santa suit shows up a month after this sells out in some other advent calendar or set
....if it doesn't though, WOW what an exclusive but that's too good of a suit to be used ONLY on Yoda. I would however lean more towards a Jango or Boba Claus.
On a side note, given that every advent calendar has has a single item per day I'm guessing there will be lot's more than just what's on the cover. Maybe mouse droids, sentinels, and countless other oddities but it should be a nice mix. And for the droid haters, at least it's a pilot droid and not a standard droid.
