From the Super Mario Wiki
Toodles is a wealthy Toad who lives in the ritzy neighborhood of Poshley Heights in the game Paper Mario: The Thousand-Year Door. Toodles' name might be a pun of "toodles", another way to say goodbye stereotypically associated with posh or wealthy people, especially women.
She likes to flaunt her wealth by wearing expensive fur dresses and luxurious jewelry. It is unknown how Toodles amassed her vast fortune; however, the game indicates that she is a gold digger, using her physical attractiveness to leech off the wealth of men. In fact, when Mario first met Toodles, she was standing in the lobby of the Glitz Pit, looking for the champion so that she could flirt with him when he arrived. She even ignored the (apparently) attractive Mario as she waited. However, once Mario claimed the title for himself, Toodles's flirtatious advances shifted as well.
Later, Mario runs into Toodles on the Excess Express. After her stay in Glitzville, Toodles decided to return to her home in Poshley Heights via the luxury locomotive. During the three-day trip back home, Toodles lost her Gold Ring, which was later found and returned by Mario. Unfortunately, she, along with the other passengers, were absorbed into the Smorg monster that attacked the train. Eventually, Mario and his allies defeated the Smorg and saved the wealthy Toad, allowing her to arrive safely in Poshley Heights.
