Princess Peach as a baby with a pink pacifier. Even though she's an infant, she wears her crown with all the charm and elegance you would expect from a princess. In Yoshi's Island DS, she rode out for adventure just like Baby Mario—on Yoshi's back. While riding Yoshi, she can use her parasol to extend their hang time.
