Edited for Syndication: The following footage and dialogue from Mechanised Mayhem was restored on the DVD set, which was unseen on Nickelodeon and syndication. It's where DM and Penfold see the Frog's Head Flyer trying to kick down the door of Greenback's hideout—Stiletto issues an S.O.S., and Danger Mouse responds:
Stiletto: Oh, signor Danger Mouse! We are under a-screw!
DM: "Under a-screw?" Oh, you mean under attack.
Plus the full ending, which was not used since it was the first episode of a two-episode screening on Nick:
Narrator: And with that, we say farewell to any hope of getting on Radio 3. (Sigh.) Oh, by the way, the management requests that you park next to a Danger Mouse transmission at your own risk. Claims for carpets, elbows and mass hysteria cannot be entertained. (Hmph. Why should they? You weren't.)
Edited for Nickelodeon: during the show's first run (1984-87), scenes from "Lord of the Bungle" and "The Bad Luck Eye of the Little Yellow God" were cut due to scenes of African jungle natives, and "Bandits, Beans And Ballyhoo!" (first appearance of El Loco) was left out altogether. All were added in during the second run (1991-94).
Name's the Same: Around the time the episode "Don Coyote And Sancho Penfold" was being made Hanna-Barbera developed a series for American TV with a character named Don Coyote. His sidekick was Sancho Panda.
