Book of Sealing

The Book of Sealing is an item in Paper Mario: Sticker Star.

History
The Book of Sealing is a book that is given to Mario by the supposed proprietor of the Enigmansion. It rests in the basement on a special pedestal.

It used to hold all of the Boos that terrorized the mansion. However, the Boos are set free, and the Toad is scared out of his house. He gives the book to Mario, tasking him with re-capturing all of the Boos.

When exploring the Enigmansion, Mario encounters many Boos. After defeating them in battle, they are automatically sealed inside the book. There is no way to tell how many Boos have been captured or are yet to be captured, but if Mario places the book on its pedestal in the basement before he has captured all the Boos, it shakes violently and Kersti suggests that there are more ghosts to be captured. Otherwise, it glows and Kamek appears.
