Can someone identify these Ninjago face mosaic sets?
Apparently it's from a 2015 Toys R Us building event, in which there were 5 different mask kids could choose to build. There does not appear to be an item number associated with these builds.



All 5 designs and 3 of the instructions can be seen in these images (click for full-size).

 

I also found a video where all 5 are built and the booklet is flipped through.
