Ivan really likes this birthday present.

Here he is consulting the instructions.

And creating the robot stack.

What could possibly make these robot stackers cooler?

If you said “putting a small Wookiee on top” you got it right.

We also would’ve accepted the answer, stacking the robots nine tall and chanting, “Here comes the Wookiee walking,” then knocking the whole thing over with a small plastic Wookiee.
