In this season, The Grim Adventures of Billy & Mandy is a standalone show, separate from Evil Con Carne, although the ninth episode, a sketch of Malo Con Carne is tied with other two episodes of Billy and Mandy.

There were 9 regular episodes in this season, and the half-hour Halloween special, in which Billy, Mandy and Grim face against Jack O'Lantern.

Other characters that make major appearances include Mandy's nemesis, the popular and snobby Mindy; Nergal Jr., the son of Nergal and Billy's aunt, Sis; and Jeff the Spider (voiced by show creator Maxwell Atoms), who is hatched from an egg by Billy.

Other characters that return are Hoss Delgado, who battles zombie brownies alongside Billy; and Eris, who keeps scheming to create chaos

However, when Grim went for Jack's soul, Jack stole his scythe. In return for his scythe, Grim promised Jack eternal life, but after closing the deal, Grim cuts Jack's head off.

To stop Jack from carrying on with his vengeance, Mandy sets up a series of pranks for him. However, the pranks affect Irwin instead, causing major laughter from Jack and his ghouls, which explode and return to the Underworld. In the end, Grim recovers his scythe and sends Jack to the Underworld too.
