All of Morton Koopa Jr.'s voice clips from New Super Mario Bros. Wii, provided by Lani Minella and reused in New Super Mario Bros. 2, New Super Mario Bros. U, New Super Luigi U, Smash 4, Super Mario Maker 1, Smash Ultimate, New Super Mario Bros. U Deluxe, and Super Mario Maker 2. Bizzarely, Morton is voiced by a female despite having a deep, masculine-sounding voice, which would last until David Cooke took over the role starting with Mario Kart 8. TBH, I can't decide between Lani and David's takes on the character, as both fit him very well. In any case, Morton is certainly one of the more underrated Koopalings. New Super Mario Bros.
