Can someone identify these Ninjago face mosaic sets? I have 2 built 6x16 sets that appear to be Ninjago portraits. Each built on a Light Bluish Gray 6x16 plate with 1x1 colored bricks on top.  I suspect they may be Toys R Us builds but i just can't find them.

Does anyone know the set name or # or link to instructions?
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.
