Sushie

Sushie is Mario's seventh party member in Paper Mario. In Super Paper Mario, Sushie appears as a Catch Card found on the eightieth floor of the Flopside Pit of 100 Trials, along as on a photo in Mario's house.

History
At Lavalava Island, Mario enters Yoshi Village and finds that five Yoshi children are missing. Their babysitter, a Cheep-Cheep named Sushie, asks Mario to help her find them. When they find the 5 Yoshis, Mario tells Sushie about his quest. Sushie says it's a very romantic story and joins the party.

By pressing C-Down, after Mario reaches a dock, Mario can swim on the surface of water and dive if he presses C-Down again.

Sushie has a daughter named Sashimie. During the game, Sashimie sends her mother a letter, stating that she is going to have a baby, meaning Sushie will soon be a grandmother.

Trivia

 * Like the other Paper Mario partners, Sushie was originally going to appear with updated sprites in the sequel, Paper Mario: The Thousand-Year Door, however she and most of the others were removed for unknown reasons.
 * Sushie is the only partner in Paper Mario that didn't have any prior knowledge of Mario (as she, herself, states that she's never heard of him).
 * Sushie is referred to as "he" and "him" on the Super Rank description.
