Season 1
Murial and Eustace Bagge live in Nowhere, Kansas. Or more aprropiately, in the middle of Nowhere.
They adopted Courage, their pink cowardly dog, when he was a pup and have been taking care of him ever since. Or vice versa actually.
Weird and scary things happen in the middle of Nowhere and Courage is constantly helping Murial out of trouble.
There is no love lost between him and Eustace, who calls him Stupid Dog, and the two of them are constantly at each others throats.
Courage by name, coward by nature, he still manages to save the day.
