In a recent interview on Nintendo's official site, Takashi Tezuka and Shigefumi Hino discuss the creation of Super Mario World and its character development. "Lots of people think that while Mario is pointing his finger forward, he's saying 'Go,' and Yoshi's tongue comes out," Hino reveals. "However, the set up that I drew was that when Mario punches Yoshi in the head, the character's tongue shoots out in surprise." But what about the fact that Mario says "go"? Hino says that originally the sound effect was a "bop" noise, but "it seemed like people would say 'Poor Yoshi'," so it was replaced by Mario's dialogue instead. Finally we know the dark truth, and poor Yoshi indeed, suffering at the hands of Mario the monster all these years. Still, back to the pineapple.
