The Slaughtering Rat People of Blorch were, as their name implies, rat-like humanoids that once inhabited the planet Blorch. That is, until it was conquered by Invader Skoodge. They make their first appearance in "The Nightmare Begins" as a holographic image, depicting Rat People attacking Invader Larb (Then Invader Skoodge), and later would make their only "real" appearance when the Irken Armada attacked their home world in "Battle of the Planets".
