This is one of those days where LEGO didn’t know what else to put in the Star Wars Advent Calendar. As with the R2-Q5 from Day 13, the Mouse Droid was included with the Death Star (10188) and the Imperial Star Destroyer (6211). It is made of 9 pieces and you really don’t need instructions to build it. A filler build that should’ve been left out I think.
