Robot Challenge #29: Design a robot that can take care of a guinea pig!(from bluemaris) 
This robot’s long brown stripe is putting the guinea pig’s poop to help the grass grow. It is sent through a long tube to a conveyor belt that cleans the poop of germs and then it is sent to the grass to help it grow. I drew the guinea pig’s butt.
