Dyllis is a chef in Super Paper Mario. She lives in Flopside in correlative to Saffron, who lives in Flipside.

Dyllis runs the Hot Fraun, a restaurant located on the first floor of Flopside that serves recipes made of two ingredients, while her counterpart Saffron requires only one item for her dishes. The player can come to the restaurant and supply two ingredients to Dyllis, which she will combine into one item. Dyllis could be described as paralleling the characteristics of Zess T., a cook from an earlier Paper Mario game, for her irritable and gruff personality.

Unlike Saffron, it is not mandatory to go to Dyllis, while you must go to Saffron and give her a Fire Burst to have her make Spicy Soup to revive Peach. However, she can make food to make the player's journey through the Flipside and Flopside Pit of 100 Trials easier.

Dyllis's name derives from dill, an herb whose seeds are used as a spice in cooking. Another analogy is Dill Pickle, since her attitude is sour. However, it is also believed that her name is a shortened version of 'delicious'.
