Steam Dozer Willy was content with his life of digging and dozing... until the day the zombie apocalypse came and turned his whole world upside down! What a drag... all these zombies lumbering around his dig site! So, Willy did what any autonomous construction robot would do. DESTROY ALL HUMANS!!! Wait a minute... all the humans are gone? Oh well, guess all these zombies will have to do until civilization makes a come back. Time to get smashing!
