"I don't decide everything about the lineup, but we did discuss that 'we have an idea to include Fox in the script for [The Super Mario Galaxy Movie], so we definitely want a new Star Fox game.' [...] Sometimes things get decided after we've discussed them. We started working on the [The Super Mario Bros. Movie] and Princess Peach: Showtime! around the same time, and we talked about things like, 'If we have this game, shouldn't Peach be more energetic in the movie too?' It was decided early on that Yoshi would appear in The Super Mario Galaxy Movie, so we decided to make a Yoshi game, and that's how development of Yoshi and the Mysterious Book began."
