Experiment 010, first nicknamed Felix, and more recently Oscar, is one of the hundreds of creatures genetically engineered by the Kweltikwan mad scientist Dr. Jumba Jookiba. This experiment, number 10, is a cleaner... only at an extreme level. It even considers living beings as dirt, dust and filth, and attempts to kill it as well. It is changed later, but gets reprogrammed a little bit too much: he becomes a dirtmaker instead.
