This is Midget Block number 130, it is called Sunbeam. The original was in orange and yellow I suppose, but I chose to do mine in three shades of blue. It should really have a different name, but I can't think of one right now.
There are just 4 empty spots on the wall and I have most of them all prepped for a trip over the river and too the woods to Grandmother's house. This one was for that as well, but got used up at piano lessons and gymnastics before the trip started. I had to prep a few Rainbow Dear Jane (RDJ) blocks just in case I run out of these.
