Dolly

Peach Dolls is a doll that look precisely like Princess Peach and is found in the game Super Mario RPG. One belongs to Gaz who likes to recreate Mario's various adventures with dolls. The second doll belongs to Booster. He used it to plan his wedding to the real Princess Peach.

They also appear in Paper Mario but go under the name Dolly. The doll belongs to Goombaria. Mario and Goompa find the toy 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.
