Trivia

 * The episode's title is a reference to the 1959 sci-fi film, Plan 9 From Outer Space
 * While Leo is driving the Shellraiser, you can see on a clock that the time is "2:21". This could be a reference to this episode's series code (221).
 * In typical fashion of some modern anime watchers, Casey says he would rather watch the subtitled version of the show, as he hates dubbed anime. This is known in the anime fandom as the "Dubs vs. Subs" dilemma.
 * This episode has a similar premise to the 80's TMNT episode "The Old Swticheroo" where Splinter and Shredder switch bodies, as well as the episode "Raphael drives em wild" where Raphael switches bodies with a cabbie named Oscar.
 * When Raph and the Kraang switch bodies they also switch voices too, but in the show they both sound the same to everyone in the show. This is so the viewer won't be confused.
 * In the scene where Raph escapes from the other Kraang he is making various noises that Jerome Lester Horwitz, better known as Curly Howard of the Three Stooges, made during his career as Curly.
 * For a brief moment we see Mikey wearing his white undies in the final scene.
 * Skelelord, the villain in SRMFF, is an obvious parody of Skeleton King from Super Robot Monkey Team Hyperforce Go! and Skeletor from He-Man.
