Dr. Peach

Dr. Peach is the "doctor" version of Princess Peach and one of the playable characters in Dr. Mario World. Like the other characters, she has a unique special ability: when activated, a pink beam of light appears and clears a random column on the board. Unlike other characters, who wear white labcoats, hers is a soft pink. Notably, Peach had previously been depicted as an assistant to Dr. Mario as "Nurse Toadstool," although this was confined to supplementary materials, aside from a woman resembling her in prototype builds of the original Dr. Mario.

Prior to this, Dr. Peach appeared mainly as a nurse in illustrations in the original games under the name Nurse Toadstool, later Nurse Peach. However, she never appeared in the games herself.
