Porter

From the Super Mario Wiki

Porter is a Toad that is found during the events in Paper Mario: The Thousand-Year Door. He is the porter of the Excess Express, hence his name, and checks the Train Tickets of passengers before letting them onboard. Porter loves trains so much, he is said to have billions of model trains in his home.

[edit] Trivia

• Perhaps intentionally, in the Nintendo GameCube game Animal Crossing, there is a porter monkey at the train station, whose name is also Porter. The Porter in Thousand-Year Door may be a reference to the Porter in Animal Crossing.
