This sixth season has eleven regular episodes. Midway through this season, the special episode "Billy and Mandy Moon the Moon" was shown, and the TV movies Billy & Mandy's Big Boogey Adventure and Billy & Mandy: Wrath of the Spider Queen had first aired. Also, this season is the first to be produced in 16:9 widescreen.
In this season, special debut appearances are made by Pinface (a parody of Pinhead from Hellraiser); the mummy of the Pharaoh King Popen Locken, who is Irwin's maternal grandfather; the Abominable Snowman, who is to be reaped by Grim; King Triceps, ruler of the ocean, and his daughters Hariel and Uvula (parodying The Little Mermaid); Hector Con Carne and Major Dr. Ghastly (from Evil Con Carne), who try to recruit General Skarr back to their army; Lionel Van Helsing, a vampire hunter seeking to destroy Dracula; and Del Uglio, a Mexican luchador, who turns out to be Billy's identical twin brother.
Lord Pain returns, now serving Mandy, instead of Grim; the Secret Snake Club is also back, now trying to avoid physical education; Nergal and his family engage in a pizza war against Billy, Mandy and Grim's own pizzeria; Nergal Junior and Irwin battle for the strong and possessive romantic love they have for Mandy; Dracula is revealed to be Irwin's paternal grandfather; Nigel Planter discovers the supernaturally dark and evil truth behind the lightning-shaped scar on his forehead; and Billy, Mandy, and Grim find themselves in Mexico to save the Dia de los Muertos festivities.
In the episode "Heartburn", the last and final regular episode of the series, Mandy temporarily overcomes her dark and evil nature and finally romantically kisses Irwin on the lips. She quickly goes back to her old sinister, power-hungry self. There is also an Austrian therapist called Dr. Hans Frankfurt who was seen in the episode "Everything Breaks" and the Wrath of the Spider Queen movie.
