Cute Robot Valentine Box

While at my daughter's class Valentine's day party, I saw a boy with the cutest box. Each child was supposed to decorate and bring in a box to hold their Valentine cards. This one was by far the best. He used a small box, empty can, large beads, pipe cleaners, construction paper, ribbon, squiggly eyes, and tin foil. This was the result.

For the back of the robot, they cut out a small door in the box and attached pipe cleaners and foil covered beads to keep it closed.

I'm not sure what he used for the feet. I forgot to ask him about that part. Any ideas?
