The Cat-Poop-Powered Robot is an invention created by Willem Viceroy originally for Bash Johnson's science fair project in Attack of the Killer Potatoes. It's a machine that could turn cat poop into energy. Unfortunately for Bash, Marlene Driscoll marked this project with a C. The robot was fully activated when the killer potatoes created from the Fart Box shooting Bucky Hensletter's potato-remote project were rampaging through the gymnasium and destroying everyone's science projects. Randy as the ninja was able to destroy it by forcing it to smash all the potatoes, causing it to slip and fall on the mashed vegetables and explode. The robot was later dropped off at Scrap City.
