Automatons can come in many shapes and sizes. You can get giant robots, who will one day rise up and kill us all, and you can get tiny little novelties, like this Paper Mario box.
It's not the most advanced thing in the world, but there's a simple charm to it that makes it endearing. Much like the little plumber himself.
If you're technically-minded there's instructions at the link below.
