Heff T. plays a somewhat major role during Chapter 6 of this game. Heff T.'s room is two away from Mario's on the Excess Express. Heff T. is also the culprit of the stolen pot of stew case. He apologizes for his actions saying he couldn't wait for the food any longer. Heff T. also gets captured by the Smorg later in the chapter until Mario defeats it.
- His name is a pun of the word "hefty" which describes his overweight appearance.
- Heff T. may be a reference to Gourmet Guy from Paper Mario as they both are overweight characters, they love to eat, and that they are always seen holding utensils (Heff T. holds a spoon and a fork while Gourmet Guy holds a knife and a fork).
