Trivia

 * If Mario gets a Starman in Super Mario Bros. 3 and subsequent remakes and games, he will be able to spin jump, and when he does, he will be covered in a sheath of rainbow energy. This bears strong resemblance to the Screw Attack.
 * Mario and Luigi: Partners in Time features an enemy similar to the Nightmare boss in Metroid Fusion called the Snoozorb. Similarities include both of their names pertaining to sleeping.
