Ghost T.

Ghost T. is a deceased Toad in Paper Mario: The Thousand-Year Door who died on the Excess Express many years before the game's setting and now exists in limbo between this world and the next (in cabin 004, to be precise). The name "Ghost T." is a pun on "ghosty", which is a diminutive of "ghost".

In order to get him to appear, enter room 004, and use Vivian's Viel move and wait a while. Ghost T. will appear inside room 004.

As with many ghosts, he is trying to resolve earthly conflicts before moving on to the next life. He lingers on the train because he left his Diary in the baggage car and does not want anybody except himself to read it (reason unknown). Mario retrieves the diary for him and gives it to Ghost T. Soon, a column of light shines on the specter, and he begins to ascend into the next world. However, he stops partway up, deciding to stay in the earthly realm; his reason for staying is that he likes the wallpaper of his train cabin. He died on the Excess Express because the dish he ate in the dining car had a Poison Shroom in it. Ghost T.'s death did not affect the seemingly famous train, and even reading his diary (which will result in him destroying Mario with a Dizzy Dial-like animation) reveals no information, simply stating that Ghost T. "got on a train" at an unknown time and ending with the phrase "And on that train...", at which Ghost T. would appear and deliver the aforementioned Game Over.

He has a side-quest to offer. The conductor will state something about a "person with no ticket" onboard, holding onto some blanket. He asks to retrieve the blanket. Talk to Ghost T., and he will give you (or show you actually) the Blanket for an exchange. He left some Diary onboard that he wants no one to read. The diary is located in the Baggage area, right behind the Conductor. Its located behind some boxes labled "Food" in a tight spot (reachable VIA Paper mode). Bring him back the Diary, and you'll get the blanket the Conductor wants. WARNING!!!: Whatever you do, DO NOT READ THE DIARY!!! Ghost T. specifically warns you not to read it, or suffer a cursed fate (not the ones the Black Chest Demons offer, more horrid than that). If you open it, you are warned 3 times not to read it. If you ignore all the warnings, the Diary will say some gibberish about he got on a train, and it ends there. Ghost T. will appear from the Diary and yell at Mario for his ignorance, and forces him to suffer. The screen will start spinning (like what King Boo did to Luigi in Luigi's Mansion), the screen's curtains will cover and open, with Mario on the ground, defeated. GAME OVER!!!

Later on in Paper Mario: The Thousand-Year Door, Ghost T. writes an e-mail to Mario. He does so by possessing the Conductor of the Excess Express, as he himself cannot hold physical objects (something he himself notes to Mario upon first meeting the plumber). Also, he somehow managed to leave a note on Rogueport's bulletin board, possibly by possessing the conductor (or someone else) yet again.

Along with Heff T., Ghost T. stays on the Excess Express for the remainder of the game.

Tattle

 * "That's Ghost T. He's a pretty lighthearted for a ghost. But still... A ghost is a ghost!"

Trivia

 * On his message to Mario, he had to possess the conductor since he can't carry physical objects, yet he was able to hold his diary.
 * Ghost T. stated he could not leave his room. However, reading his Diary brings him out of that room. In addition, he possessed other character (unknown if they actually went inside that room).
 * Ghost T. himself can cause a Dizzy Dial animation, like King Boo. However, he does it more than once.
