Trivia

 * Rockin' K.K. may be based on the battle music of the New Age Retro Hippie enemies - as well as Franky Fly - from EarthBound, which is a pastiche of "Johnny B. Goode" by Chuck Berry. The name could also be a reference to the main protagonist of EarthBound, Ness, who possesses a signature move called PSI Rockin. Unlike Rockin' K.K., the "Hippie Battle Theme" does not appear in Super Smash Bros. Brawl (likely due to copyright issues), though it can be found within the game's files.
