When Courage cannot do anything correctly, the “teacher” approaches him, who is the manifestation of Courage’s own doubts and insecurities that have plagued him. She trains him strictly into becoming a perfect dog, but in the end, Courage learns that there is no such thing as perfect. Later, as the episode concludes, it is implied that Courage has accepted the fact that he is perfect the way he is, and eats at the dinner table with a happy Muriel and Eustace. The fish from before is shown cooked on the table, and he gives the audience a thumbs up, concluding the series.
