The Letter "p"
The Letter "p" is a special item in the game Paper Mario: The Thousand-Year Door.
Mario and Vivian needed The Letter "p" to guess Doopliss's name, because while guessing his name, their letter options lacked this letter. This was also a very clever way to prevent people from cheating (by looking up Doopliss's name on sources such as player's guides and the internet). Although a capital "P" is always available when Doopliss prompts Mario and Vivian to guess his name, using it won't work, for the spelling must be case sensitive.
To find the letter, Mario is forced to use Vivian to access a secret portion under the well in Creepy Steeple, using her Veil power. There, Mario can roll up into a tube and access a treasure room, where one of the chests contains the letter. By using Veil again, a parrot in the room reveals Doopliss's name for the player.
Trivia
- Doopliss is called "Ranperu" in Japan. The missing letter in the Japanese version is "n" (though in the katakana alphabet) rather than the English "p".
