Trivia
- The nighttime setting of this world should not be confused with the underground setting of World 1-2 and World 4-2. Although the sky is black, no other objects' colors are affected. As a result, in Hard Mode, the Buzzy Beetles are almost invisible.
- This and World 6 are the only two worlds in Super Mario Bros. that are set completely at night.
