Dolly

A Peach Doll is a doll that looks precisely like Princess Peach. They first appeared in the game Super Mario RPG: Legend of the Seven Stars. One Peach Doll belongs to the Toad Gaz, who likes to recreate Mario's various adventures with dolls. The second doll belongs to the deranged Booster. He used it to plan his wedding to the real Princess Peach.

A Peach Doll also appears in Paper Mario. The doll belongs to Goombaria (who calls the toy "Dolly"). Mario and Goompa find the doll in Jr. Troopa's territory, implying Jr. Troopa stole the doll from Goombaria. After Mario returns the doll to Goombaria, he'll get a Star Piece and a kiss.

Additionally, a Peach Doll is one of Peach's Presents in Mario Party 4, although this one is shaped more like a matryoshka doll.

Another Princess Peach toy, known as the Mini Peach, appears in the game Mario vs. Donkey Kong 2: March of the Minis.
