Baby Peach

Baby Peach's first appearance was in the Nintendo DS game Mario & Luigi: Partners in Time. Baby Peach is Peach's younger self in the past. She got to the current time Mushroom Kingdom through a time machine that Prof. E Gadd created. She is also going to appear in the upcoming game Yoshi's Island 2 for the Nintendo DS along with Yoshi, Baby Mario, Baby Donkey Kong, Baby Wario, and Baby Bowser.

In Mario & Luigi: Partners in Time, Toadsworth was always looking over her just like he does with the current time Peach.
