I made a YouTube video about today’s models.
Guardians of the Galaxy’s model is a Nebula minifigure in an ugly Christmas sweater featuring herself and Thanos on the back in a heart. (Thanks to Jay’s Brick Blog for filling in for my failed memory.)
Here are all three models together.
My original model with the parts so far (days 1-9 from the three calendars) is this blue and white kitty cat.
