Excess Express

A luxury choo-choo train Mario and his comrades ride to get to Riverside Station and Poshley Heights in Paper Mario: The Thousand-Year Door. During that time, unfortunate events happen, hindering Mario and keeping him from getting the sixth Crystal Star. There's two main mysteries: The chef's pot is stolen, and the train will be blown up, if Mario wasn't on board. He also runs into a hoard of strange black creatures on their way.
