Trivia

 * When Rosalina appears for first time in the blooper, she's partially disappears for a few seconds due to a glitch that SMG4 didn't notice before he uploaded the video on a Monday evening as he was tired. So he only saw it the next day and then told his fans to ignore that part of the blooper.
 * In SMG4's canonity, Rosalina's secret admirer is Professor E. Gadd..
 * She devotes some of her time to "Story Time" where she and dozens of lumas go inside a little house on her space ship and she reads stories to them (mostly gay/perverted stories like "Everyone Poops" 50 Shades Of Gray" and "Twilight", also stating that the lumas are partially gay and/or perverted).
