Robot Investigator

"A lone robot investigates an abandoned planet. What happened to the inhabitants? Who were they? Robot Investigator follows a lonely robot on an expedition to a mysterious planet that looks a lot like Earth. The story unfolds like a parallel universe Wall-E as the robot explores what appears to be a pristine landscape. He meets curious gerbil-like animals and stumbles upon a band of feral humans. Who were they? Why did they turn into wild men? Robot Investigator is both sweet and melancholy, cute and grisly. Stall's silent sequences are drawn with an inky, lush, and elegant line filled with expressionistic colors."
