Courage the Cowardly Dog follows a dog named Courage, an overly-frightened canine who lives in a farmhouse with Muriel and Eustace near the fictional town of Nowhere, Kansas. Abandoned as a puppy, Courage was adopted by Muriel Bagge, a sweet-natured Scottish woman, and her husband, Eustace, a grumpy, greedy farmer who harasses Courage with a large, bright green, bug-eyed mask, while saying, "Ooga Booga Booga!" Courage, Eustace, and Muriel Bagge constantly run into monsters, aliens, demons, mad scientists, zombies, and other perils that Courage must fend off to save his owners. Most of the creatures Courage, Eustace and Muriel face are scary or creepy, but they also can be sweet or in distress.
