"Quailman VI: The Dark Quail Saga" is the 30th episode of Doug in the Disney era. It first aired on October 4, 1997, on ABC.
In the scene by the "Doug" logo, Quailman tries to put on his Power Briefs, but crashes into place. By the premiere, Doug tells Patti that he will cry if she goes with Guy. Quailman tries to save Ms. Mayonnaise, but Rubbersuit traps him under a big foot. The Golden Salmon rescues Quailman and revives him. Later, the Golden Salmon disguises himself as Rupert Schmupert. Rubbersuit yanks out Quailman's evil twin, the Dark Quail. A giant slug slithers into the room slips into a Rupert Schmupert suit and mask and tries to get to Ms. Mayonnaise. After splitting the Dark Quail back together, Quailman tries to warn her about dating a giant space slug. Quailman asks Patti to share his Quail Powers with her, and gives his Quail Belt to Patti, who puts it on. Patti, who uses Quailman's powers, unmasks the slug, and kisses Quailman. After the dream ends, Doug asks Patti that she can go skating on Sunday, but she can't, and he moans painfully. Seconds later, Doug is joined by Patti.
