The Adventures of Mighty Plumber

Mighty Plumber is a fictional TV show in The Adventures of Super Mario Bros. 3. The cast apparently consists of Mighty Plumber; the protagonist and title character, and an unnamed woman who is always getting herself into plumbing-related trouble. Mario and Luigi love the show.

Bowser zapped Mighty Plumber out of the television and his show in Misadventure of Mighty Plumber, the show's only appearance. He told him that Mario and Luigi were evil plumbers, and they were going to rob the Pipe Land Coin Treasury (which he had been trying to plan to rob earlier).

Once King Koopa's plan was foiled at the end of the episode, Mario forced Cheatsy, who had the Magic Scepter that could zap things out of the TV in the first place, to put Mighty Plumber back in his show. At the very end of the episode, Mighty Plumber seems to give the Mario Bros. a thumbs-up from his show.
