Other mistake: On the "Mario's Greatest Movie Moments" DVD of this series, from the main menu, go into the trivia game. The fifth question asks you about the Super Mario Bros. Super Show episode 'Count Koopula.' It asks you "What's room number that the Mario Bros. were put into in Koopula's Castle?" It's supposed to say "What's THE room number that the Mario Bros. were put into in Koopula's Castle?"
