|First Appearance||Don't Drink the Water|
Verminous Skumm is one of the eco-villains. He is a large, mutant rat, born and raised in a sewer. Skumm is determined to take over the Earth.
Skumm wears tattered and dirty clothing - a blue jumpsuit that is torn and dishevelled, and a red scarf wound around his head and face. He often hides in shadows or covers his face. He favours the underground. He was originally voiced by actor Jeff Goldblum. After five episodes, Goldblum left the role and was replaced by voice actor Maurice LaMarche.
Skumm has an army of rats at his disposal. Some are enormous and clothed, like him, but he is also able to communicate and control the regular rat population.
