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?"
Other mistake: In many of the live-action segments, the Alarmtron logo on the alarm in the Mario Bros' residence has been partially covered to read "Acarmtron" instead. In addition, in several episodes, the phone number for Alarmtron is also partially covered.
