Each year the LEGO Group releases a selection of advent calendars to count down the days until Christmas with a small build behind every window. While Star Wars, City and Friends are all back this year, Harry Potter has been introduced to the festive countdown collection for the first time.
The Christmas tree theme continues in the Harry Potter calendar, with this one featuring snow, without being as complete snow buried as those from yesterday. It is one of the best LEGO minifigure-scale Christmas trees yet.
In the Star Wars edition, the build is much less inspired, designed to interact with the First Order Stormtrooper from yesterday.
Things are getting cute in Friends, with a little hamster or similar critter riding on a sled.
Wrapping up day four is the little snow castle, that is intended to be used as a target for the catapult from yesterday.
