The Creepy Steeple Boo is a character that appears in the game Paper Mario: The Thousand-Year Door. He resides at the Creepy Steeple for the remainder of the game.


The Creepy Steeple Boo is first seen after Mario has opened a treasure chest that contained many Boos in it. The Creepy Steeple Boo then asks Mario a question on how many Boos were in the chest. If Mario guesses correctly (which is 200), The Creepy Steeple Boo gives Mario an Ultra Shroom. Later in the game, The Creepy Steeple Boo then sends Mario an email thanking him for freeing him and his friends earlier. He then tells Mario that there are treasures that might be still in the Creepy Steeple if he were to visit again (most likely referring to the secret room near the entrance that contains the Cookbook and a Shine Sprite).


  • Oddly enough, The Creepy Steeple Boo is able to send an email normally despite being a ghost. Ghost T. had to take over the conductor of the Excess Express in order to send Mario an email.
