In an interview, the producer of Nintendo's 3D Mario series, Mr Koizumi, recalls a funny story when Miyamoto was directing them to develop the game, according to overseas media. At that time, Miyamoto will also discuss with the first-line developers the creation of "Mario" series of works. Mr Koizumi recalls that in the morning after working two or three consecutive nights, Miyamoto was in the office discussing how Mario should move. "It was just the two of us who, when he explained to me how Mario should swim in the game, suddenly leaned over his desk to imitate the frog swimming," he said. Koizumi smiled and regretted not having taken this scene. Originally Mario in the game to show the swimming posture is with Miyamoto learned "but Miyamoto not a hint of embarrassment or shy, he is very serious to do the explanation." This brings me a lot of touches, I think I met a real director of the game. "Today, Koizumi's independent role in the production of 3D Super Mario Galaxy series has been a great success, and he was also very grateful to Miyamoto gave him such a lively lesson."
