Dolly

A Peach Doll is a toy that looks precisely like Princess Peach, appearing as a key item 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.
