In this game, they, like the Black Yoshis, can eat things that normal Yoshis cannot, like Red Peppers and Black Shy Guys. White Yoshis can also flutter further when they're a Super Happy Yoshi, and fire eggs that explode when their happy meter is full. Also, while the Black Yoshi has the lowest pitched voice, White Yoshi has the highest pitched voice. If White Yoshi is lost, White Shy Guy cannot bring him back unless the game has been completed with White Yoshi in the party at least once.
