Trivia

 * Caety Sagoian (Bowser Jr.) and Deanna Mustard (Princess Daisy) do not reprise their roles as their characters due to union issues with the IATSE, both of their roles are replaced by Lauren Tom.
 * Mercedes Rose was unable to reprise her role as Rosalina, so Samantha Kelly voiced her instead.
