At her castle, Princess Peach had just gotten done hosting a press conference with her beloved populous as she handed the reigns to Toadsworth. She retreated to her bedroom, smiling at the sight of you sitting on the bed as she removes her crown and disappears in a puff of smoke. In her place stood a normal looking female Toad smiling at you, though this one was wearing a smaller version of Peach's dress and had pink heart shapes on her head.

This would be Peach's true form.
