- This episode was released on Disney XD Southeast Asia on March 19, 2015 before it premiered in the USA.
- RC9GN Director Joshua Taback posted a video of the process for drawing three seconds of rough animation for the show. The final product shows Randy as the Ninja running around a room picking up stuff and heading to an arcade video-game while jumping up and down, McFist and Viceroy watching him.
- Howard at one point calls Randy "Ninjaleh," which would presumably be the Yiddish for "little ninja" (along the lines of common Yiddish endearments such as "bubbe" and "boychik," which Howard also employs); this not only refers to Howard's being Jewish, but the common perception that Jewish people have been particularly influential in show-business and commerce. Both Howard and Randy adopt typically "Jewish" New York style accents as well.
