“Want me to cook something for you, Clumsy Crush-a-lot?”
—Zess T., Paper Mario: The Thousand-Year Door
Zess T. is a grumpy fifty-five year old Toad chef in Paper Mario: The Thousand-Year Door who resides in Rogueport. Zess T.'s name is a pun of the word "zesty", which, in a way, describes her personality, as well as being a reference to her cooking skills. Like Tayce T., she is an expert at cooking, but she is the polar opposite; she has a sour attitude and is very mean and grumpy, calling Mario names and keeping a mean expression on her face. Her attitude is similar to Dyllis.
Mario first comes across her as she is searching for her missing Contact Lens; after Mario accidentally steps on it and crushes it, Zess T. refuses to allow him into Rogueport's West Side until he buys her a new one. Even after he does, Zess T. still harbors a bit of a grudge, referring to him as names such as "Stompy" or "Sir Stomps-on-Stuff".
Her cooking is limited to one item at a time until Mario finds Maitre Delish's Cookbook hidden in a back room of Creepy Steeple. After completing this task, she is able to cook two items into one.
