In both of the Super Mario 64 games, Peach is unplayable.
Peach first appeared as a redhaired woman with a white dress in the original Super Mario Bros.
Peach's first name was actually Princess Toadstool , until it was changed to Princess Peach in Super Mario 64.
Peach almost always wears her pink dress. She only does not in the Mario Sports series and some Mario Kart games.
