The Case of the Burrowing Robot

Hank has faced every hardship imaginable-natural disaster, disease, and all kinds of monsters. But, this time, he finds himself up against a creature he's never seen before-and boy is it scary! Someone-or something, a bizarre robot with beady eyes and a full suit of armor-is digging up the garden. Hank is on the case immediately, but before he can put an end to the armored creature's antics, he gets blamed for the crime. Can Hank dig his way out of this mess, or has he burrowed too deep?
