Kroodi

Kroodi is a fictional species from the animated television series "Invader Zim." They are a race of diminutive, slug-like aliens who are known for their exceptionally foul odor and their habit of consuming anything they can. Kroodi are often depicted as being unintelligent and prone to simple-minded actions, yet they can be surprisingly effective when working together. In the series, a group of Kroodi were employed by the Irken Empire as janitors and sanitation workers. They were tasked with cleaning up the messes left behind by the Irken soldiers, which often involved dealing with hazardous materials and alien waste. Despite their unpleasant nature, the Kroodi were generally loyal to their masters and performed their duties without complaint. Their appearance is characterized by their slimy, gray skin, large, bulbous eyes, and a gaping maw filled with rows of sharp teeth. They move by slithering and leave a trail of slime wherever they go. The Kroodi's primary role in "Invader Zim" was to provide comic relief and to further illustrate the bizarre and often grotesque nature of the show's universe. Their lack of sophistication and their revolting habits served as a stark contrast to the more technologically advanced and seemingly organized Irken Empire.
