Market-Based Title: The Japanese packaging lists the game as Super Mario World: Super Mario Bros. 4, but the subtitle was eliminated elsewhere (including its own home country).
New Work, Recycled Graphics: As pointed out by Geno on her Tumblr, the graphic style of the game has been used in at least seven games, each using the same sprite for Mario, but at the same time using different front facing graphics for Yoshi, and different sprites altogether for Bowser
According to a 2017 interview with the game's developers, Mario would have punched Yoshi on the head to make his tongue go out or to breathe fire. Most of the team agreed that this would be too mean for Mario, so they changed it to him simply pointing instead◊. Many however, either by mistake or intentionally misinterpreted this as them confirming that Mario is in fact punching Yoshi in the final game.
Fan Nickname: Fans of the cartoon have called Luigi "Emo Luigi" because of him crying in "Gopher Bash".
Screwed by the Network: NBC gave this treatment to the cartoon's entire run. Viewers relying on word-of-mouth rather than commercials just to catch a new episode was the first straw. Being produced on a smaller budget than The Adventures of Super Mario Bros. 3, and thus limiting the episodes to one segment in each Captain N episode, instead of two with Super Mario Bros. 3, was the second straw. The last straw, however, came when NBC halted production of the series without any prior announcement, then canceling it and its fellow NBC cartoons altogether as part of NBC's take-down of their Saturday morning block and replacement by teen-oriented TNBC. Its time slot was then occupied by local news.
