The Rat and the Weasel are two villains from the animated TV series Courage the Cowardly Dog. They are two wicked animals that own a Demon Mattress. Rat is hunch backed, with brown fur and red eyes, and a stitched scar on his side. Weasel has purple fur, a rattlesnake tail, a big, blue, bug eye and a normal eye.
After "The Demon in the Mattress", Rat and Weasel were not seen again until "Courage in the Big Stinkin' City", where they drove Courage to the creepy tower.
