With this little box of 392 mini building blocks, you can build a Great Horned Owl.

For ages 12 and up (all the others say that) even though their site says 7 which is where we got the image.  Small pieces can be a choking hazard.  The company says they are suitable for any age under adult supervision.  We put a couple together and they look great.  Some of the pieces are really tiny.
