During the events of this game, Chef Shimi can be seen in the kitchen on the Excess Express. However, at some point, his pot gets stolen and a crime scene goes underway. Mario manages to track down the culprit as Heff T. and after Mario gives back the pot to Chef Shimi, the chef will reward Mario with a Star Piece.
Chef Shimi has also put up a trouble at the Trouble Center. His trouble involves bringing him three specific items: a Mystic Egg, a Golden Leaf, and a Keel Mango. A Mystic Egg can be received from Petuni after playing a game with her at The Great Tree, a Golden Leaf can be found hidden in the Creepy Steeple, and a Keel Mango can be found on Keelhaul Key. After bringing Chef Shimi these items, he will reward Mario with 40 coins.
- Chef Shimi's name is a reference to "sashimi" which is a Japanese food dish that uses fish.
