Advent 2017 Day 23

The penultimate entries of this year’s CityFriends,  & Star Wars Advent calendars are a trio of sleighs, and in Christmas Build-Up a Christmas tree; I made a black bird MOC with the leftover parts.

The first of the three sleighs is in City, and it can be towed by yesterday’s snowmobile:

Similarly we get another one in Friends, that can be towed by yesterday’s pony:

In Star Wars we get a self-propelled one:

With remaining parts, I built a MOC of a black bird:
