The Grim Adventures of Billy & Mandy (season 1)

The first season of the American animated television series The Grim Adventures of Billy & Mandy originally aired on Cartoon Network in the United States from August 24, 2001, to October 22, 2004. It consisted of 18 episodes, including the 49 Grim & Evil episodes, one exclusive episode, and the half-hour Halloween special (also made originally for Grim & Evil), in which Billy, Mandy, and Grim face against Jack O'Lantern.
